Let’s say a big earthquake occurs somewhere in the world and you want to know a bit about it. This can be accomplished quickly by using broadband data from the IRIS DMC (Data Management Center) and some coding in Matlab. In this excercise students will learn to download .sac files from the DMC and load those files into Matlab for examination. The activity focuses on enabling students to locate the event based on P arrivals and then caculate the magnitude of the event.
This exercise was developed by Susan Bilek at New Mexico Tech (sbilek@nmt.edu) and used as part of the IRIS Interhsip Oritnation Week.
Students will be able to:
EqLocate is an interactive app that allows users to locate earthquakes using real seismic data from recent and historic events.
Easily plot stations and distance circles on an interactive world map to demonstrate how earthquakes can be located using the time difference in the arrivals of P and S waves at a set of seismic stations.
jAmaSeis is a free, java-based program that allows users to obtain and display seismic data in real-time from either a local instrument or from remote stations.
