What is a natural disaster beginning with o?

Answer 1

One natural disaster that begins with the letter "O" is an "earthquake." Earthquakes occur when there is a sudden release of energy in the Earth's crust, resulting in seismic waves. They can cause significant damage to buildings, infrastructure, and the environment, and can trigger secondary disasters such as tsunamis and landslides. Although not commonly referred to with the letter "O," the term "overland flooding" may also apply to certain flooding events in specific contexts.
