【Disaster News】Natural Disasters Just Drained $400B – Your Wallet Is Next

Imagine 3

Did you know natural disasters drained over $400 billion from the global economy last year? Your wallet might be next.

2024 was the hottest year since 1850, with catastrophic consequences. We faced 21 separate billion-dollar disasters worldwide, with insurers covering only $154 billion of the total $417 billion in damages.

Hurricanes Helene and Milton were the costliest events, each causing about $20 billion in insured losses alone. Meanwhile, severe thunderstorms and hail contributed a staggering $64 billion to the insurance bill.

As a disaster management expert, I’ve watched climate patterns shift dramatically in recent years. What’s truly alarming is how wildfire and storm seasons are becoming increasingly unpredictable – like the January fires we saw in Los Angeles, completely outside the traditional season.

Our old preparedness playbooks are becoming obsolete. In my experience, communities that adapt now with flexible emergency plans will save both lives and money when – not if – disasters strike.

Day_202 : What is Inland Flooding?

When it rains heavily on a flat area, the rainwater does not drain away and accumulates on the ground. Water flows into low areas from surrounding small elevations. Drainage canals and small rivers are the first to overflow as water levels rise. Floods that occur in this way are called internal floods and are distinguished from external floods that occur when the levees of main rivers break or overflow. In general, internal floods include the overflows of relatively large drainage rivers that have their source in the plain and the overflows of small rivers on plateaus and hillsides into lowlands at the bottom of valleys. Floods caused by internal flooding are particularly problematic in cities and surrounding newly developed urbanized areas. What is called “urban flooding” is the flooding of urban areas, which is intensified by the structure of the city and creates new types of damage, such as the inundation of underground malls.

Day_138 : Natural Disasters in Europe (1)

Natural disasters in Europe mainly consist of hydrological, meteorological, climatological, earthquake and volcano eruption disasters.

Figure   The Europe

Earthquake disasters mainly occur in the Aegean Sea, the south-western coast of Balkan Peninsula, and the southern part of Italy. Volcanoes are active in the central and southern parts of Italy, the southern Aegean Sea, and Iceland area.

Concerning hydrological, meteorological, and climatological disasters, heavy rain and storm disasters are caused by low  pressure in the Icelandic area developed in the winter season. A cold atmospheric current coming from Arctic gains a warmer vapor stream from the Gulf Stream and develops a strong atmospheric depression in the area. This causes the strong winds and high tidal waves along the coastal areas of the North Sea.

Netherlands and England can be highlighted. The Netherlands had storm surges in 1530 and 1570. The death tolls were approximately 400,000 (1530) and 70,000 (1570) for each. The 1953 depression took an 1800-person death toll. This disaster also reached England. England’s disasters were the 1703 Thames river flood and the 2003 Heatwave. The temperature was 8–10 over the average year in August 2003.

With regard to earthquake disasters, Italy, Greece, and Portugal are the main countries to be affected.

The following past article explains the recent earthquake cases in Italy.

Day_85 : Shingen Embarkment: SAMURAI Disaster Risk Management

Those who can rule the water can also rule the country. This proverb became a reality, especially during the Sengoku period (Warring States Period) in Japan.

Shingen embankment was a flood control system built over 400 years ago to protect the northern part of the Kofu Basin, the rich rice paddy areas of Kai Province, then under the rule of Daimyo (District Lord) Shingen Takeda. The main problem is that the Midai River, a left branch of the Kamanashi River, is the major branch of the Fuji River, Once the Midai River flow increases and broke the bank protecting the Kofu Basin at its confluence with the Kamanashi River, the flood damage to the paddy fields was extensive. Such floods were known even in prehistoric times. Towards AD 1500, Shingen Takeda, the Daimyo (District Lord) of Kai country, directed that flood control works be made to protect the rice paddy area of his country (Takeuchi, 2003*).

Shingen Takeda was one of the strongest Samurai Daimyo (District Lord). He controlled his soldiers well and so did the floods.
