Montana Regional Seismograph Network
• 34 MBMG telemetered analog stations
• 1 MBMG strong-motion + SPZ channel
• 47 stations from 9 other networks
• Total: 82 stations/167 channels recorded in real time

Short Comings
• No backup coverage during absences in a one-person office
• Badly behind on routine event analysis~500 events in August 2005
~200 events June 26, 2006 to present
• ~ 1 year behind on digital ML analysis
• Need to more efficiently analyze network data• Research on network data is sacrificed for the
sake of routine analysis and maintenance

Other Issues
• Incorporating USArray data into regional network operation
• Integrate USGS strong motion instruments into regional network
