Day_140 : Natural Disasters in Europe (2) Vajont Dam Collapse

Figure   The Europe

Concerning hydrological, meteorological, and climatological disasters, heavy rain, and storm disasters are caused by a low  pressure in the Iceland area developed in a winter season. A cold atmospheric current coming from Arctic gain a warmer vapor stream from the Gulf Stream and develop the 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. Netherlands had storm surges in 1530 and 1570. The death toll were approximately 400,000(1530) and 70,000(1570) for each. The 1953 depression made 1800 death toll. This disaster reached to England also. England’s disasters were the 1703 Thames river flood and the 2003 Heatwave. The temperature was 8-10 over than an average year on August 2003 (Day_38).

Danube, Elbe, Rhine, and Seine rivers are on the gentle slope make slow inundations caused by heavy rains. On August 2002, the Central Europe had a heavy rain, this makes Danube and Elbe rivers overflows in Germany, Czech, Austria, and Hungary. The death toll is approximately 100, affected is over 100,000. Historical Buildings in the city such as Prague,Dresden, and so on along the rivers were also inundated.

Alps mountains have had landslides, debris flows, slope failures, and so on. The particular example is the landslide in Dolomites, North Italy in 1963. Overflows from Vajont dam caused by large-scale landslide attacked the village in downstream ares.The death toll is approximately 2600.

A brief explanation


An Interviews based explanation

On August 2003, the West Europe had 8-10 degrees celsius higher than the average. This heat wave killed 15000 in France, 7000 in Germany, 4000 in Spain, 4000 in Italy, and so on, totally 35000.

In summer 2010, Russia had a heat wave and this makes wildfire. The wildfire was spread out and it took over 1.5 months to extinguish.Many villages were destroyed by the fire. The Moscow was covered by harmful smoke. Over 55,000 were killed by the heat wave and the smoke in Russia.
