TERRAscope is a wide dynamic range, very broad-band
seismographic network in Southern California. It is owned and run by the
Caltech Seismo Lab. Each station consists of a Streckeisen seismograph, a
strong ground motion sensor, and a barograph. The data is recorded on-site
using the 24-bit Quanterra datalogging system and collected by the Caltech
Seismo Lab.
This map shows the location of the TERRAscope stations.
Click on any (PAS, GSC, ISA, BAR for now...) triangle for more information
