Earthquakes and Seismic Events Earthquakes result from the sudden release of accumulated stress along geological faults, generating seismic waves that shake the ground. Volcanic Eruptions Volcanic hazards arise from the expulsion of magma, ash, and gases from a vent or fissure in the Earth's crust.
Categories of Natural Hazards: Geophysical Types
These hazards are characterized by their immense energy and often sudden onset, leaving little time for natural adaptation. The 2004 Indian Ocean tsunami starkly illustrated the immense destructive power of these hydrological events, capable of traveling vast distances across ocean basins.
Tsunamis Tsunamis are series of ocean waves with extremely long wavelengths, usually caused by undersea earthquakes, landslides, or volcanic eruptions. They can be riverine, affecting inland areas, or coastal, driven by oceanic forces.
Geophysical Types of Natural Hazards: Earthquakes, Volcanoes, and Tsunamis
Because they strike without warning, earthquakes remain among the most challenging hazards to predict, despite advances in monitoring tectonic plate movements. While often perceived as slower-onset events compared to earthquakes or tsunamis, they are increasingly severe and pose significant risks to global food security, water resources, and human health.
