Day_55 : Tsunami Surveys in Hawaii

After the Indian Ocean Tsunami in 2004, we started collecting information on the tide gauge records around the Indian Ocean. In 2008, we also discussed the emergency management aspects for future possible tsunamis in the Indian Ocean at Pacific Tsunami Warning Center (PTWC)*, International Tsunami Information Center**(ITIC), and Univ. of Hawaii Sea Level Center(UHSLC)***.

*Pacific Tsunami Warning Center
We can confirm the present tsunami warning information.
The PTWC is the world’s core center for tsunami warnings.
As you may know, the tsunami is a Japanese word. The name comes from the Hiro village (many Japanese settlers lived there) in Hawaii, severely affected by the tsunami in 1968. The villagers called the wave “Tsunami.”

**International Tsunami Information Center
They have important historical tide gauge records.

***University of Hawaii Sea Level Center

We can confirm the sea level is rising around the globe.

The famous Hitachi company’s symbol image tree in Hawaii was found.

Day_106 : Myanmar-This week’s earthquake and the past trends

Myanmar had a huge earthquake (M6.8) on 24Aug2016.
The outline of the information can be checked by the ADRC website (Figure 1).

“A powerful 6.8 magnitude earthquake struck central Myanmar, killing at least three people and damaging nearly 200 pagodas in the famous ancient capital of Bagan. The quake was also felt across neighboring Thailand, India and Bangladesh, sending panicked residents rushing onto the streets (AFP).”

Let’s check the disaster data.
The Figure 2 Figure 3 are the 1900-2016 top 10 deadliest and costliest disasters  in Myanmar (EM-DAT).

Figure 3 Total damage (Top 10 costliest natural disasters in Myanmar)

We can confirm how the 2008 Cyclone Nargis was influential.
Many natural disasters which have high total deaths numbers occurred before 2000 (7/10).  On the contrary, many high economic damage natural disasters hit after 1990 (8/10).  These facts support the following “disaster is from human suffering to economic damage with development process”.

The notes on the recent major events (ADRC) are as follows:

1) Cyclone Nargis (May 2008)
Cyclone Nargis hit Myanmar in May 2008 which killed 84,537, with the missing 53,836, injured    19,359. 450,000 houses were destroyed, with another 350,000 damaged. Total affected people     were 2.4 million. The total economic loss was US$ 4.1 billion (according to Post-Nargis Joint         Assessment- PONJA).

2) Indian Ocean Tsunami (December 2004)
Indian Ocean Tsunami occurred off the Sumatra Island on 26 December 2006 killed 61,                 injured 42, affected 2,592 and destroyed 601 houses in Myanmar.

*The numbers of deaths are not the same with different sources. This is the one of the most important challenges of disaster research.

We can especially consider the political conditions for understanding the 2008 Cyclone Nargis disaster exacerbations. During the disaster, the county had refused international aids.
