Basic Earthquake Information

Basic Earthquake Information

An earthquake is the shaking that results from the movement of rock beneath earth’s surface.

Earthquakes are measured by magnitude

Magnitude means the strength based on seismic waves.

Damage caused by earthquakes

Damage caused by earthquakes Earthquakes can cause

landslides, tsunamis, and can knock down buildings.

WavesWaves

Earthquake waves are called seismic waves.

Two types of seismic waves are surface waves and body waves.

Two types of body waves are primary waves ( P- waves) and secondary waves( S- waves).

Two types of body waves are primary waves ( P- waves) and secondary waves( S- waves).

Body Waves Body Waves

P- waves travel at about 1 to 5 miles per second depending on the material it’s traveling through.

S- waves come after P- waves. P- waves move faster than S- waves.

An elastic rebound is an explanation for how energy is spread during earthquakes.

The Tohoku EarthquakeThe Tohoku Earthquake

The earthquake occurred Friday March 11, 2011 at 2:46 pm at epicenter time.

The quake occurred at 38.322 degrees north, 142.369 degrees east.

The magnitude of this quake was 9.0, near the northeast coast of Honshu, Japan.

Effects on the economy of Japan

Sony’s six factories in the region were affected by the earthquake

No idea when Sony will re-open Assembly plants for Toyota, Honda, Nissan were closed

The Japanese economy threatens to suffer another bout of recession

Nuclear plants have problems

GPS SensorsGPS Sensors

One interesting fact about the earthquake in Japan is that it moved several GPS sensors.

This will require all GPS sensors to be reset

Certain things wouldn’t be there because of elastic rebound
