Seismic phases and earthquake location

Topic: Earthquake Measurement PSSA: A / S8.D.1.1.

 Energy travels as seismic waves which are vibrations caused by earthquakes.  All earthquakes start beneath the earth’s surface.

Goal  Locate the epicenter of an earthquake. What is an Epicenter? A point on the surface of the Earth directly above the FOCUS of the earthquake. The.

Epicenters Infer an earthquake’s epicenter from seismographic data.

 Most earthquakes occur at Plate Boundaries  The deepest earthquakes occur at subduction boundaries.

Speed Velocity and Acceleration. What is the difference between speed and velocity? Speed is a measure of distance over time while velocity is a measure.

How do we find the distance to the epicenter from a station?

Global earthquake explorer – a simple example for students

GEE- an IRIS and University of South Carolina product

My earthquake for This example – March 17, 2011 M = :47:59.0 GMT Vanatu Islands Depth 15 km

Seismograms displayed by distance from earthquake

Number of display options Display arrival times can also align seismograms by P arrival, origin time, data begin time

Seismograms aligned By P arrival time – easy for students to determine S-P arrival time and get distance from earthquake to each station

Zoom in on Specific seismograms

Can also select earthquake directly With a series of parameters – Lat/long, magnitude, depth, or date
