Elementarrisiken

Ein Elementarrisiko (englisch Natural hazard) ist die Bedrohung durch ein "natürliches" Ereignis (Naturkatastrophe), welches negative Auswirkungen auf Menschen und Umwelt haben kann.

Viele Elementarrisiken sind kausal miteinander verbunden. So kann(z.B. ein Erdbeben einen Tsunami auslosen und eine Dürre kann Hungersnot und erzwungene Migration zur Folge haben..

Ein konkretes Beispiel für die Unterscheidung zwischen einem  Elementarrisiko und einer Naturkatastrophe bietet das San Francisco Erdbeben von 1906. Das Erdbeben an sich war eine Naturkatastrophe, während die Siedlung am Rande des Andreasgraben ein Elementarrisiko darstellt.

Welt insgesamtlarge areas subject to severe weather (tropical cyclones); natural disasters (earthquakes, landslides, tsunamis, volcanic eruptions); volcanism: the world is home to more than 1,500 potentially active volcanoes, with over 500 of these having erupted in historical times; an estimated 500 million people live near these volcanoes; associated dangers include lava flows, lahars (mudflows), pyroclastic flows, ash clouds, ash fall, ballistic projectiles, gas emissions, landslides, earthquakes, and tsunamis; in the 1990s, the International Association of Volcanology and Chemistry of the Earth's Interior, created a list of 16 volcanoes worthy of special study because of their great potential for destruction: Avachinsky-Koryaksky (Russia), Colima (Mexico), Etna (Italy), Galeras (Colombia), Mauna Loa (United States), Merapi (Indonesia), Nyiragongo (Democratic Republic of the Congo), Rainier (United States), Sakurajima (Japan), Santa Maria (Guatemala), Santorini (Greece), Taal (Philippines), Teide (Spain), Ulawun (Papua New Guinea), and Unzen (Japan)
