Aim: What are Earthquakes and their characteristics? I. Earthquakes – any vibrating, shaking, or rapid motion of Earth’s crust. A. Fault – zone of weakness.

Earthquakes! An earthquake, or seismic event, is a sudden movement of Earth’s crust that releases energy.

Earthquakes. What causes Earthquakes? Earthquakes are sudden movements or vibrations in the earth’s crust. They are caused by faulting and folding activity.

Earthquakes An earthquake is the shaking or trembling of the earth caused by the _Sudden_ movement of the earth’s crust. They usually occur where rocks.

EARTHQUAKES. INTRODUCTION TO EARTHQUAKES Earthquake = a vibration of the Earth produced by the release of energy. Seismology is the study of earthquakes.

Earthquakes and Volcanoes p What is This?

 Earthquake = the shaking and trembling that results from movement of rock beneath Earth’s surface  Focus = area beneath Earth’s surface where rock.

Earthquakes A sudden shaking of earth as rocks break along a fault or plate boundary A sudden shaking of earth as rocks break along a fault or plate boundary.

  The location underground where an Earthquake begins is the focus.  The crust breaks at the focus, and the released energy pushes outward in all directions.

What is an Earthquake? Shaking or trembling of the Earth’s surface Creates seismic waves

Sudden movements in Earth’s crust What causes Earthquakes? Sudden movements in Earth’s crust Stress builds up until rock finally breaks Volcanic activity Landslides Nuclear Tests

Earthquakes do NOT cause the crust to move- The moving crust causes Earthquakes!!

Where do Earthquakes usually occur? Plate boundaries and faults

Parts of an Earthquake: Focus Underground location of event that causes earthquake

Earthquake: Epicenter Parts of an Earthquake: Epicenter location of an earthquake on the surface directly above the focus.

What’s the largest Earthquake in the U.S.? Alaska 115 died-- most deaths due to the tsunami Shaking was felt earthquake of March 27, 1964. It had a magnitude of 9.2. for an estimated 7 minutes raised or lowered the ground approx. 56 feet in some places. length of the ruptured fault was 621 miles. energy released was equal to 12,000 Hiroshima-type blasts.

Largest in World… Chile (1960)- 9.5
