Geological Hazards
This frame illustrates six geological hazards as follows:
- Earthquake: An earthquake is the sudden movement of rock masses within the Earth's crust caused by the abrupt release of energy. This energy propagates as seismic waves from the focus toward the Earth's surface, resulting in ground shaking.
- Sinkhole: A sinkhole is a depression or deep cavity on the Earth's surface, typically formed due to geological processes such as rock collapse, karst processes in carbonate rocks, or erosion.
- Landslide: A landslide refers to the rapid or slow movement of soil or rock masses downslope, triggered by rainfall, earthquakes, or human activities.
- Tsunami: Tsunamis are very long-wavelength sea waves generated by submarine earthquakes, volcanic eruptions on the seafloor, or underwater landslides.
- Tornado: A tornado is a violently rotating column of air over a localized area with extremely high wind speeds and significant rotational density.
- Volcano: A volcano is an opening on the Earth's surface through which very hot molten materials, gases, and partially or fully melted rocks are expelled or ejected from the interior of the Earth.
