Floods are considered one of the most catastrophic natural disasters. They affect more people than any other natural disaster, posing serious risks for people’s lives, properties and infrastructure. Due to the increasing frequency of severe flood events, as well as evidence of global climate change and rise in sea levels, floods are now considered a serious threat.
On 25 August 2005, Hurricane Katrina hit the densely populated south-eastern part of the US state of Florida with squalls of 130 kilometres per hour at maximum speed, and caused extensive damage. Fatal floods were generated by the precipitations.
Mt. Etna, located in Sicily, Italy (37°44’N, 15°00’E), is Europe's largest volcano.
