Earth Science: Using Natural Hazards to Forecast Events

Mass wasting is triggered by factors that destabilize slopes, including the removal of vegetation (which holds soil), forest fires (which destroy vegetation), and earthquakes (which shake the ground).

Gravity is the fundamental force that pulls material downslope, acting as the primary driver for all mass wasting events.

Mass wasting is the geomorphological process by which soil, sand, and rock move downslope typically as a mass, largely under the force of gravity.

In tornado-prone regions, having a basement or a designated storm shelter is critical for safety, as it provides protection from high-velocity winds and flying debris.

Satellites are used for real-time monitoring of current weather patterns, cloud cover, and precipitation. They do not calculate historical rainfall totals from previous years for forecasting purposes.

Weather satellites provide critical data on cloud movement, temperature, and moisture, which are essential for forecasting various weather phenomena.

Seismic activity on the ocean floor is related to earthquakes and tsunamis, not riverine flooding. Rainfall, storm characteristics, and topography are all primary factors in flood prediction.

Earthquakes are primarily caused by the sudden release of energy in the Earth's crust, which occurs when tectonic plates shift or slide past one another.

Hurricanes and typhoons derive their energy from warm ocean waters. Higher water temperatures provide more heat energy, which fuels the storm's intensity.

While hurricane forecasting has improved significantly, it is not possible to predict them with 95% accuracy due to the chaotic nature of atmospheric systems.

Tsunamis are most commonly triggered by underwater earthquakes, which displace large volumes of water and create waves.

GPS technology is used to monitor ground deformation, such as the swelling or shifting of land around a volcano, which often precedes an eruption.

Seismology is the study of earthquakes and seismic waves. Seismometers are the instruments used to detect and measure these vibrations.
