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

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.
Hawaii Quake Detected; QCN Is Now 'Non-Alpha'
April 21, 2009
A few QCN participants caught the recent M5.1 quake in Hawaii. Also as of today I am removing the 'alpha test' status of the Quake-Catcher Network, although the URL will remain the same so you do not have to reconnect/reattach. The credit stats should now be tracked by boincstats.com
QCN Participant Machines Detect Today's San Jose M4.2 Quake
March 30, 2009
At least four QCN participant's machines detected today's San Jose earthquke. Also for the first time the external USB JoyWarrior sensor was used to detect a quake (it's previously just been Mac laptops). So keep running QCN and thanks for participating!
External USB Sensors Available
January 14, 2009
QCN's USB sensors are now available for order. The sensors are $5 for K-12 teachers, and $49 for everyone else. With your help, we can grow the network larger, better, and faster! Thanks for your support!

The 'ScienCentral' channel has posted a short (two minute) video-clip regarding the Quake-Catcher Network featuring an interview with Prof. Jesse Lawrence of Stanford.
New version 4.25, All Platforms, Tests Triggering Algorithm
November 7, 2008
New version 4.25 is up for all platforms - this version perturbs some of the sensitivity algorithm used to detect triggers. It will hopefully lead to less 'false positive' triggers/trickles as well as help us 'fine tune' our algorithm.
New version 4.22, All Platforms
November 4, 2008
New version 4.22 is up for all platforms. This has improved error handling. If you are using the JoyWarrior 24F8 external USB accelerometer, you will want to upgrade the QCN USB driver software for Intel Mac or for PowerPC Macs.
