Seismology Educators, Robert Butler and I have posted a summary of the recent magnitude 8 event in Peru, including seismograms from three AS-1 instruments.

Here are some images of the earthquake activity in the last 24 hours including a labeled image of the 24 hour seismograph record for the WLIN AS-1 station. The USGS earthquake site (http://earthquake.usgs.gov) has information on these events including the loss of life and damage from the M7.9 Peru earthquake. -Larry Braile -- Lawrence W.
