The article discusses Turkey’s earthquake history and how the nation has implemented lessons learned from past events. This analysis highlights the importance of continuous learning in order to better prepare for and respond to such disasters.

Introduction to Turkey’s seismic history

Turkey, a country bordering Europe and Asia, has suffered earthquakes before. It is incredibly vulnerable to these disasters because of its location on the seismically active Anatolian Plate. Turkey has historically seen some of the most damaging earthquakes in the world. Understanding the nation’s seismic history and drawing from its experiences can teach other countries valuable lessons on preparing for and responding to earthquakes.

A better understanding of how to predict, prepare for, and respond to these catastrophes has been made possible by the terrible impacts of earthquakes on Turkey. The country’s response plans have improved, using new engineering innovations and construction techniques to reduce casualties and property damage. In this post, we will examine Turkey’s seismic past, the significance of Adobe architecture there, and the lessons we can draw from Turkey to improve our readiness for and response to earthquakes.

Understanding earthquakes: Causes and types

Energy is released during the shifting and grinding of tectonic plates, which results in earthquakes. Large plates that make up the Earth’s crust are constantly moving and can collide, divide, or slide past one another, which can cause the ground to shake. Tectonic, volcanic, and induced earthquakes are the three main categories of earthquakes. The movement of the Earth’s plates causes the most frequent earthquakes, known as tectonic earthquakes. While induced earthquakes are brought on by human activity, like the mining of natural resources or the construction of huge reservoirs, volcanic earthquakes are brought on by the flow of magma beneath the Earth’s surface.

The Anatolian Plate, which is being compressed between the Eurasian and Arabian Plates, is Turkey’s leading cause of seismic activity. This tectonic activity has created numerous fault lines nationwide, making it vulnerable to earthquakes. For instance, the North Anatolian Fault, a strike-slip fault with a length of more than 1,000 kilometers, has caused multiple disastrous earthquakes in Turkey’s history.

The Significance of Adobe Structures in Turkey

Turkish architecture has long used adobe constructions built of soil mixed with straw or other organic materials. These constructions, frequently seen in rural locations, have served as fortifications, houses, and public facilities. The key benefits of Adobe structures are their affordability, simplicity, and great thermal qualities, which assist in maintaining a comfortable interior temperature all year round.

However, regarding seismic activity, Adobe constructions also suffer from serious drawbacks. These structures are particularly prone to collapsing during earthquakes because of their weight and low tensile strength. Throughout Turkey’s history, many large earthquakes have painfully illustrated this susceptibility, resulting in the death of countless people and extensive destruction.

Due to this, Turkey’s rising focus is on enhancing the seismic performance of Adobe structures. Researchers and engineers have been working on developing innovative techniques and materials to increase the earthquake resistance of these traditional structures and preserve their cultural relevance while ensuring the safety of their occupants’ safety.

Major earthquakes in Turkey’s history and their impact

Throughout its history, Turkey has been the site of many large earthquakes, some of which have had devastating effects. The Erzincan earthquake in 1939, the Izmit earthquake in 1999, and the Van earthquake in 2011 are three of the most famous. These seismic occurrences resulted in extensive property damage and fatalities and changed the nation’s strategy for earthquake preparedness and response.

Approximately 33,000 people perished in the 7.9-magnitude earthquake that struck Erzincan in 1939, and many more were injured or left homeless. This catastrophe made it clear that better seismic monitoring, prediction, and earthquake-resistant building techniques are required.

With nearly 17,000 fatalities and more than 50,000 injuries, the 1999 Izmit earthquake, which registered a 7.6 on the Richter scale, was among the deadliest and most catastrophic in modern Turkish history. The significant destruction brought on by this incident highlights the significance of strengthening earthquake preparedness and response strategies.

The most recent earthquake, the 7.1 magnitude Van earthquake in 2011, significantly damaged the Adobe structures in the area, killing over 600 people and displacing thousands more. This catastrophe also emphasized the necessity for improvements in construction methods and supplies for Adobe to improve its seismic performance.

Day_174: Unraveling the Twister Mysteries: A Captivating Dive into the Science of Tornadoes

 

One of nature’s most potent and destructive forces is the tornado. These storms, with wind gusts exceeding 300 miles per hour, have the potential to harm homes, businesses, and entire communities seriously. However, what gives rise to tornadoes, and how do they develop such enormous strength? This article examines the science underlying tornadoes, including the atmospheric factors influencing their development and the most recent findings, mainly focusing on the US cases.

What Factors Lead to Tornado Formation?

Warm, moist air from the Gulf of Mexico and cool, dry air from Canada are two of the atmospheric factors that combine to create tornadoes. A huge, unstable atmosphere is produced when these two air masses clash, which can result in the development of powerful thunderstorms. These thunderstorms frequently produce tornadoes because the spinning of the storm stretches and condenses a column of air, forming a funnel cloud.

Although thunderstorms are a requirement for the development of tornadoes, not all thunderstorms result in tornadoes. In actuality, tornadoes only sometimes form during thunderstorms. This is because certain conditions, such as significant levels of wind shear—the change in wind speed and direction with height—are necessary for tornadoes to occur. The revolving column of air within a thunderstorm may tilt due to wind shear, producing a horizontal spinning motion that can result in the development of a tornado.

The Anatomy of a Tornado

Despite coming in various shapes and sizes, tornadoes all possess a similar structure. The vortex, a rotating column of air extending from the cloud base down to the ground, forms the primary body of a tornado. This vortex is encircled by a turbulent cloud of dust and debris, often visible in the form of a funnel-shaped cloud.

Tornado strength is quantified using the Enhanced Fujita Scale, which rates tornadoes on a scale of EF0 to EF5 based on the destruction they cause. EF0 is the weakest tornado, with winds ranging from 65 to 85 miles per hour, while EF5 is the strongest, with winds exceeding 200 miles per hour. The strength of a tornado is determined by the speed and intensity of the rotating column of air within the vortex.

The Fujita Staircase

The Fujita Staircase graphically displays the Enhanced Fujita Scale and its corresponding levels of damage for different categories of tornado strength. It consists of six steps labeled F0 to F5, each representing a specific level of tornado intensity. The staircase aids meteorologists and emergency managers in evaluating tornado damage and devising plans for tornado preparedness and response.

The Difference Between a Tornado Watch and a Tornado Warning

When weather conditions are favorable for tornadoes to form, a tornado watch is issued. Although no tornadoes have been reported, there is a high probability of severe thunderstorms and tornadoes in the area. During a tornado watch, it’s important to stay informed about the weather conditions and be prepared to take action if a tornado warning is issued. On the other hand, a tornado warning is issued when a tornado has been sighted or detected by radar. This means that a tornado is imminent, and you need to take immediate action to protect yourself. In case of a tornado warning, seek shelter in a sturdy building, preferably in a basement or an interior room on the lowest level of the building.

Tornado Safety Tips

Living in an area prone to tornadoes requires preparation and knowledge of what to do during a tornado. To stay safe, keep these tornado safety tips in mind:

– Stay updated on the weather conditions by monitoring local news and weather reports.

– Have a plan in place for where to go and what to do in case of a tornado. Identify a secure location in your home or workplace, preferably in a basement or an interior room on the lowest level of the building.

– If you’re driving and a tornado approaches, seek shelter in a strong building or take cover in a ditch or low-lying area. Avoid trying to outrun a tornado in your car.

– If you’re caught outside during a tornado, find shelter in a low-lying area, like a ditch or culvert. Cover your head with your hands and avoid trees and other objects that could fall on you.

The Deadliest Tornadoes in History

Throughout history, tornadoes have left behind a trail of destruction and loss of life. Some of the deadliest tornadoes on record are as follows: The Tri-State Tornado of 1925 claimed 695 lives and caused injuries to over 2,000 people in Missouri, Illinois, and Indiana; The Natchez Tornado of 1840 resulted in the death of 317 people and injuries to over 1,000 individuals in Mississippi and Louisiana. The Joplin Tornado of 2011 caused the loss of 158 lives and injured over 1,000 people in Missouri. These catastrophic storms serve as a warning of the immense power and destructive force of tornadoes, emphasizing the significance of staying prepared and informed.

Tornado Chasing and Research

Many meteorologists and weather enthusiasts have taken up tornado chasing as a thrilling hobby. With the help of specialized equipment such as radar and GPS, chasers monitor the formation and movement of tornadoes. Although this activity comes with risks, it has greatly contributed to our knowledge of tornadoes and their behavior.

The study of tornadoes has been greatly aided by scientific research. Through the use of advanced tools like Doppler radar, satellite imagery, and computer modeling, scientists have gained a better understanding of the atmospheric conditions that give rise to tornadoes, as well as the factors that determine their strength and behavior.

How Climate Change Affects Tornadoes

Researchers are studying the potential impact of climate change on weather patterns worldwide, particularly concerning tornadoes. While there is still much to learn about the relationship between climate change and tornadoes, some experts suggest that rising temperatures and alterations in atmospheric circulation could cause an uptick in tornado activity in certain areas.

Moreover, climate change may also trigger changes in tornado patterns, such as more frequent outbreaks and shifts in the timing and location of tornadoes. These alterations could have significant implications for preparedness and response efforts related to tornadoes.

Final Remarks

The sight of a tornado is both awe-inspiring and terrifying, as it is one of nature’s most powerful phenomena. Although the science behind its formation is intricate and multifarious, our comprehension of these storms is constantly expanding. By examining the mechanics and behavior of tornadoes, we can predict and prepare for their impact, ultimately reducing the damage and destruction they cause. Therefore, should you hear a warning siren, it is important to remain informed, prepared, and most importantly, safe.

Day_172 : Hollywood Movie “The Beach” and The 2004 Indian Ocean Tsunami in Thailand

Past writings are to be disclosed little by little with some changes.

>>>>>>>>>>>>>>>>>>>>>>>>>>>>

The Supreme Court of Thailand ordered 20th Century Fox Inc. and its local subsidiaries to restore the ecosystem of Phi Phi Island, acknowledging that the company degraded the environment around Phi Phi Lei Island for the filming of the Hollywood movie “The Beach” in 2000 on December 7, 2006. The film, starring Leonardo DiCaprio, has made great strides in the development of tourism on the island and displaced many tourists, but the island was one of the worst affected areas by the Indian Ocean Tsunami of late 2004, and many tourists lost their lives.

Flyer: The Movie “Tha Beach”

Tourism development for economic development and environmental issues lay largely in the background of why Koh Phi Phi was one of the hardest-hit areas by the tsunami in Thailand.

It all started with the baht crisis that hit the Thai economy in 1997. In the early 1990s, the Thai government established the Ministry of Science, Technology and Environment and the Environmental Fund, enacted a number of environmental laws and enacted a national environmental boom, which began in the early 1990s. A prime example is a controversy over the alteration of the environment for Hollywood movies, known as “the beach controversy,” which began in 1998.

This was sparked by an attempt by a film crew to alter the landscape of Maya Beach on the island of Phi Phi Ley. For the filming of football game scenes, the sandy beach was widened by bulldozers and non-indigenous coco palm trees were imported and planted on the beach to create an image of a tropical paradise. The Royal Forest Department’s decision to approve the alteration was a measure that went so far as to bend the law in order to attract international investment with the aim of reviving the Thai economy.

This has led to the neglect of nature conservation, and local NGOs and others have begun to investigate and prosecute the environmental degradation around the island.

The tsunami that struck Phi Phi Island on December 26, 2004, occurred in the midst of such tourism development.

Now, two years after the tsunami, the island of Phi Phi Lei and the surrounding areas have regained their natural beauty, having been cleared of the man-made nature created by the tsunami.

Mr. Songboon of TOT Krabi Province, a major telecommunications company in Thailand, said, “I’ve been watching Phi Phi Island for a long time, but the sea was the dirtiest just before the tsunami. He said with great emotion, “The beaches around the area after the tsunami have regained the beauty of 10 years ago. He is currently staying on Phi Phi don Island to set up an internet connection.

Mr. Spar, who runs a dive shop in the hard-hit Thongsai Bay, said, “For a while after the tsunami, we were in a vicious circle, with fewer customers and higher rates for the limited accommodations available to stay, and even fewer customers. However, now the sea itself is getting very clean and the city has recovered a lot, and the customers have returned. Management is getting a little better, too. and a glimpse of hope.

Supreme Court decision that seems too little too late. It will be interesting to see how Phi Phi Island rebuilds and learn from the experience of the tsunami and its recovery process.

Day_171 : Past Interview Records – PTWC (Pacific Tsunami Warning Center) in Hawaii (2)

Interview Records at PTWC　No.2
2008.2.26 (Tue.)　at 1000 am

The records from the interview survey are shown below.

■ Science and technology
Many models of the tsunami have been developed. However, it is difficult to adopt because it is crucial whether it is practical or not.

■ Staff training
Only internal training is available.

■ A system where Civil Defense gives warnings to citizens.
There is a hotline to the provincial government and another one to the federal government.

■ Work shift
One person is always at the center for 24 hours.
8hr-4hr-4hr 4hr 16hrs are in shift
When there is a problem, three staff gather at the center.

■ Backup
The center’s backup is at the Alaska center and if Hawaii doesn’t work. Alaska center can cover.

■ Relationship with media
Concerning the media, media is, in a sense, a partner.
Civil Defense needs 3 hours before the event to evacuate. for that reason, there are too many time constraints. The media is fast. However, there are various restrictions. To decide to proceed with the warning or not, the media has no such authority. Also, in the United States, the media is a business and not state-owned, so it could mislead. You must always pay attention to the points.

■ Resources
Before the tsunami damage of 2004, the conditions were very limited in resources. A lot of money was invested in this field since the events of the year. The function of the center has been improved because of that. The staff has increased. The 2004 event was a severe tsunami disaster by letting the world know the reality.

Day_170 : The methodology of the Research on the communities and workers sustainability in the industrial complex area affected by the 2011 Chao Phraya Flood  

Basically, we proceed with a top-down process for the research. The followings are the outlines of the procedures for the surveys: 1) Rojana Industrial Park and Japanese companies and their responsible persons 2) Communities: Community leaders, employees, and critical facilities and their responsible persons.

1) Rojana Industrial Park and Japanese companies and their responsible persons
The followings are the reasons why Japanese companies and why Rojana Industrial Park in the central region of Thailand are selected for the project. The first, 451 of 804 inundated companies in the central region of Thailand caused by the 2011 flood were Japanese related (Tokyo Marine & Nichido Fire Insurance Co., Ltd., 2011). The second, the Rojana Industrial Park, is one of the seven inundated industrial parks in the central region of Thailand. Rojana Industrial Park is also deeply related to the Japanese company because Rojana Industrial Park was established as a joint venture between Japanese (Nippon Steel & Sumikin Bussan Corporation) and Thai (Vinichbutr’s Group) companies in 1983. The Japanese target companies are mainly selected through the connections with the Japanese Chamber of Commerce Bangkok and Japan External Trade Organization (JETRO). The responsible persons are chosen totally up to the companies. The representative Japanese and Thai managers and persons in charge of BCP or risk management of the companies are chosen to meet our needs. We conduct focus group interviews and questionnaire surveys for the above persons and employees in the companies. Questionnaires are distributed and collected in the box in the canteen of the companies.

2) Communities: Community leaders, employees, and critical facilities and their responsible persons
A top-down approach in data collection is applied by gaining the necessary authorization from the senior-level officials such as Chief of DDPM Ayutthaya and Chief district office, which subsequently facilitated reaching out to Tambon and Mooban leaders through the District office. This approach proved useful in establishing the proper and assured contacts to conduct the surveys in the target area.

Firstly, we ask permission to do surveys from the Ayutthaya governor and the chief of the DDPM Ayutthaya office. Second, we are introduced to meet the target Amphoe Uthai chief and ask him to communicate with the four target Tambon leaders. Third, we asl Tambon leaders to introduce the thirty-five Muban leaders and also the persons in critical facilities in the area. After the process, we conduct the employees’ surveys. The target persons, 400, are randomly selected with the recognition of the Muban leaders based on the Yamane formula. We also proceed with the interview surveys to our prioritized twenty-five critical facilities acknowledged by the Tambon and Muban leaders. The representatives or the persons in charge of risk management in the critical facilities are required to answer the questions.

Day_169: The 2011 Chao Phraya River Flood Literature Reviews

Regarding the published literature, there are several approaches to investigate the 2011 flood.
Mark and Lebel (Mark and Lebel, 2016) describe how Thailand’s incomplete decentralization and administrative fragmentation has created numerous barriers to polycentric disaster governance.

Hagiwara et al. (2014) explained the chain reactions of the economic damage mainly derived from the experience of Japanese enterprises and points out issues that disrupted their businesses. That paper focused on the risk management changes of the firms after the 2011 flood, indicating they have strengthened their flood countermeasures as a whole, but points to the need to consider more about the collaborations with business partners or other entities.

Okazumi and Nakasu (2013) (2015) examined the devastating exacerbation of economic damage through a social background perspective and enterprise inter-relationships.

Nakasu (2017) clarified the reasons why so many Japanese companies moved to the potential risk area in Thailand. The reasons are from the perspective of both the country’s social factors through decentralization policies facilitated by the Thai government and also yen appreciation triggered by the Plaza agreement (1985) and the Lehman Brother’s bankruptcy (2008) to propel Japanese enterprise relocation and advancement.

Haraguch and L. Upmanu (2015) emphasized the decision-making process of enterprises to clarify the trigger of economic damage. That paper proposed measures for related supply chain risk through setting research questions such as private investment decision-making, the diversified sources of procurement, emergent assistance from other partner companies in the same supply chain, and the degree of the recovery of customers.

Tamada et al. (2013) approached the subject mainly from economic, political, hydrological, and technological perspectives with various authors. That book clarified the complexity of the 2011 flood and overviewed how human interventions affect the disaster, such as local people’s lifestyle changes before the disaster, the establishment of the industrial complexes in the area, government agency conflicts, dam operation impacts, unexpected rainfall, and private company reactions.

Singkran (2017) reviewed the 2011 flood from disaster management views and emphasized the need for more non-structural countermeasures and participatory collaboration among stakeholders for effective disaster management.
