Quake-Catcher Network Seismic Monitoring

About Quake-Catcher Network Seismic Monitoring

The Quake Catcher Network (QCN) is a research project that uses Internet-connected computers to do research, education, and outreach in seismology. You can participate by downloading and running a free program on your computer. Currently only certain Mac (OS X) PPC and Intel laptops are supported -- recent ones which have a built-in accelerometer.

QCN is a joint project between Stanford University and University of California at Riverside.

New QCNLive versions (5.34)

November 9, 2009
New versions of QCNLive for Mac and Windows have been developed which allow you to record the sensor output in a 'csv' (comma-separated values) format for import into spreadsheet software such as Excel. Also web links to the USGS site have been updated to reflect the new USGS website layout.

QCN Supports 64-bit Mac and Windows

June 26, 2009
New versions have been put up which support 64-bit Mac OS X and 64-bit Windows (XP and Vista) operating systems. If you are running the BOINC Mac Universal client or the BOINC Windows x64 client it should automatically detect this and download the correct version. The 64-bit versions do not support the MotionNode Accel USB accelerometer at this time.

There are also 64-bit versons of QCNLive for Mac available here (actually a universal binary for PowerPC, Intel 32-bit, and Intel 64-bit). There is a 64-bit Windows QCNLive available here

Please post any problems in the Message Boards!

QCN Participant Detects M4.5 earthquake in Southwest Germany

May 5, 2009
A Quake-Catcher Network participant detected a magnitude 4.5 earthquake in SW Germany, near the borders of France and Switzerland using his JoyWarrior USB sensor and QCN/BOINC. This is a fairly rare event to capture on QCN and we thank him and others running QCN! The participant's computer was only 10km from the epicentre.

QCN Participants Detect M4.0 earthquake in Yorba Linda, California

April 24, 2009
Two Quake-Catcher Network participants felt and recorded yesterday's magnitude 4.0 earthquake in Yorba Linda, California (southern Cal, southeast of Los Angeles). You can view some of the data at this link. They are only about 4 km / 2.4 miles from the epicenter, so it was a good test of QCN and the JoyWarrior USB sensors! Happily everyone is OK with just a few plates shaken up etc.

Minimum BOINC Version 6.2 for QCN (6.6+ preferred)

April 22, 2009
QCN is going to require a BOINC client upgrade (within the next two weeks) to at least version 6.2. This will enable QCN to run more reliably tanks to new BOINC features such as higher-priority CPU scheduling for low-CPU tasks such as QCN. Download the latest version here. We recommend BOINC version 6.6 or higher, as available on the download link, to ensure that your QCN software and sensor will work at a higher priority level, and cut down on the 'resets' especially when running other BOINC projects alongside QCN.
