Catastrophic events can cause significant destruction and loss of life. Hurricanes are massive, slowly-spinning tropical storms with strong winds that form over water, leading to storm surges that inundate coastlines. Tornadoes are rapid, whirling storms over land, while tsunamis are giant ocean waves triggered by seismic activity. Earthquakes shake the ground due to fault movement, and volcanic eruptions force materials from below the Earth’s surface. Other events include avalanches, floods, and droughts, all of which have severe implications for communities and ecosystems.
