Tsunami – a wave that forms when a large volume of ocean water is suddenly moved up or down.

This movement can be caused by underwater earthquakes, volcanic eruptions, landslides, underwater explosions, or the impact of a meteorite or comet.

As it enters shallow waters tsunami wave speed slows and its height increases, creating huge destructive waves.

Earthquake hazard measures how prone an area is to experiencing earthquakes in the future.

Earthquake Hazard An area’s earthquake-hazard level is determined by past and present seismic activity.

Nationwide Earthquake Frequency

Worldwide Earthquake Frequency

Recent Earthquakes Earthquakes

Worldwide Earthquake Frequency (Based on Observations Since 1900) Descriptor Magnitude Average occurring annually Great 8.0 and higher 1 Major 7.0-7.9 18 Strong 6.0-6.9 120 Moderate 5.0-5.9 800 Light 4.0-4.9 about 6,200 Minor 3.0-3.9 about 49,000 Very minor 2.0-2.9 about 365,000

Richter magnitude scale - Wikipedia, the free encyclopedia

Earthquake Forecasting Gap hypothesis – states that sections of active faults that have had relatively few earthquakes are likely to be the sites of strong earthquakes in the future.

Seismic gaps – an area along a fault where relatively few earthquakes have occurred.

Earthquakes in Nevada

Earthquakes and buildings Buildings are designed to withstand earthquakes by flexibility and ability to absorb shock.

Being prepared Always keep emergency kit. Keep heavy objects low/fastened. Duck and cover

OUT: How does the frequency of an earthquake compare to the magnitude of the earthquake?
