Active seismic experiment goes off with a bang. A total of 67 people participated in the deployment of 2600 seismometers across the High Lava Plains (HLP). Sixteen two to three person teams drove across the HLP for two days burying seismometers every 800 meters along lines that spanned from Bend, OR, to Idaho and from John Day, OR, to Winnemucca, NV, with a concentration of instruments between Steens Mountain and Burns, OR. The seismometers were left in place for two days while 15 seismic sources were detonated across the area. All shots went as planned and almost all seismometers performed flawlessly, providing data that will allow a reconstruction of the structure of the the HLP crust.

The seismic sources also supported additional seismometer deployments by groups from Stanford University and the University of Idaho that focused on higher resolution images near Steens Mountain. All but one seismometer was recovered intact and full of data. A party celebrating the success of the experiment was hosted by Randy Keller on September 11, and was highlighted by the debut of the HLP project theme song.
