Description:
<jats:p>On June 3rd, 2004 a spectacular bolide was reported over British Columbia, Washington, Oregon and Idaho. In addition to eyewitness accounts and video recordings, the event was recorded on a number of seismometers in the Pacific Northwest Seismograph network and at infrasound arrays in Washington State and California. Using the NRL-G2S atmospheric model for the time of the event, source locations have been determined with seismic and acoustic signals separately. Estimates of the yield and acoustic efficiency of the explosion have also been determined. By simulating the propagation of infrasound through the atmosphere, the arrival of discrete acoustic phases at the infrasound arrays has been modeled.</jats:p>
