A natural disaster is a catastrophe that results from a natural event: earthquake, volcanic eruption, tsunami, ground movements, flood, storm, cyclone, thunderstorms, etc.

 

 

Remarkable disasters

Among the innumerable catastrophes that have occurred all over the world, some are remarkable in that their peculiarities, natural as well as human, make them generic examples, school cases showing that the effects of irrepressible natural events are catastrophic only because they have been ignored, underestimated, badly warned ...

Falls of meteorites

The fall of a large meteorite is the most destructive of all natural events. That of the Tougouska was the worst of the natural historical cataclysms; ecological catastrophe, it was not a human catastrophe, as it occurred in a practically uninhabited area.

Volcanic eruptions

 

The volcanic eruption of Mount Pelee was the most deadly of the twentieth century; in a few minutes, its paroxysmal fiery cloud completely destroyed Saint-Pierre and exterminated its inhabitants, about 30,000 people. The destruction of the city and its surroundings was inevitable but not the death of its inhabitants who were the actual victims of aberrant administrative decisions to ensure the second round of a legislative election on May 11 preventing their departure, an extreme danger was evident.

Earthquakes

At the Intergovernmental Conference on Seismic Risk Assessment and Mitigation at Unesco Headquarters in Paris, during the Special Session in February 1976, Chinese seismologists presented their method of earthquake prediction applied to that of 'Anshan (04/02/1975, M 7,4), material damage - buildings, bridges, roads ... but less than a thousand victims in an area of ​​more than three million inhabitants: prediction earthquakes and the prevention of the inhabitants were therefore possible. Unfortunately, 18 months later, the earthquake in Tanshan (27/07/1976, M 7,6) proved the opposite: it caused material damage, but especially 250,000 victims according to the Chinese and probably more than 650 000 in reality; it would thus be the most deadly earthquake for more than two centuries and possibly forever.

After 1976, many violent and some catastrophic earthquakes, all unforeseen and unexpected, affected several Chinese provinces; that of 12/05/2008 in Sichuan caused nearly 90,000 victims and considerable material damage ... Then there were at least five other destructive earthquakes in China: Yushi 2010, Yunnan 2010 - 2011, Dingxi 2013, Sichuan 2013.

 

tsunamis

 

The Sendai tsunami, caused by an M 9 earthquake that occurred about 130 km off the north-eastern coast of Honshu Island, reached a local height of 30 m on the shoreline and 10 km inland.

Although it was the most violent ever recorded in Japan, the earthquake itself caused little destruction and victims, as the earthquake-resistant constructions were effective and the inhabitants were well prepared. On the other hand, the height of the tsunami exceeded the forecasts and largely overwhelmed the protective coastal works, mainly concrete port walls some of which were over ten meters high. it ravaged nearly 600 km of coastline, partially or totally ruined some 50 coastal cities, killed 8,649 people, 12,877 disappeared, 2,603 ​​injured and destroyed the Fukushima Daiichi nuclear power plant.

The power plant was built on a coastal cliff; the reactor platform was flooded at sea level to limit the cost of pumping cooling water; the height of the protective wall was about 6 m, but the tsunami reached 15 m, drowning the reactors and causing a major nuclear disaster.

Coastal Storms [

 

At the Lay estuary, the old parts of the Aiguillon-sur-Mer and the Faute-sur-Mer are built on dunes and sandy levees that shelter them from most of the floods of the river and strong tides; southward to the point of l'Aiguillon, the fragile shore of the bay is bordered by a dyke road that protects polders; this dyke was frequently chipped during storms associated with strong tides, causing the floods of polders, then strictly agricultural. Extensions and large estates of villas have recently been established in some polders.

Storm Xynthia reached the Atlantic coast on the night of February 28th. In the bay of Aiguillon, winds reaching 130 km / h produced a swell of about ten meters of hollows; the depression of 968 hPa and a tide of open sea coefficient 102 amplified the tidal bore by more than 1.5 m.

In the middle of the night, breaks in the dykes resulted in very abundant floods, very fast and persistent, which caused about fifty victims by drowning, most surprises in full sleep in their houses, recent villas implanted beneath the level of the sea ; the level of the water has locally reached the ceiling garden level, ie more than 2 m.

These villas had been built in very vulnerable sites, underestimating the risks of breaking dykes and resulting floods, while many similar events had already occurred there.
