Causes
Ocean waves monitored by the International Charter: Space and Major Disasters are most commonly tsunamis, although strong winds from storms can also create hazardous coastal waves. Tsunamis are seismic sea waves that typically result from underwater earthquakes or volcanic eruptions. However, they can also be triggered by other factors, such as ice calving from glaciers or meteorites.
Consequences
Tsunamis are powerful waves that can reach heights of tens of meters. When these waves extend over land upon reaching coastal areas, they can strike with deadly force, causing destruction and leaving flooding in their path. The impact can devastate coastal communities, leading to loss of life and severe damage to infrastructure.
Occurrence
The majority of tsunamis occur in the Pacific Ocean's "Ring of Fire," an extensive area stretching from the western coast of the Americas to the eastern coast of Russia and China, and also includes Japan, the Philippines, and many islands in the south Pacific. This region is known for being geologically active due to the meeting of tectonic plates.
Satellite data
Satellites are valuable for imaging the aftermath of a tsunami. They use optical and radar data to identify areas of damage and flooding, aiding in the assessment and response efforts.
