A view of the Boulder Mountains from US-12 west of Helena. These mountains lie at the north end of the Boulder Batholith.

Map showing distribution of average annualized earthquake loss by region. The high concentration of loss in California and the West Coast is consistent with that region’s high seismic hazard, significant population, and building exposure. 

Although most economic loss is concentrated along the west coast, the distribution of relative earthquake risk, as measured by the Annualized Earthquake Loss Ratio (AELR), is spread throughout the country and it reinforces the fact that earthquakes are a national problem.

The large HTHH volcanic explosion created fast low-frequency pressure waves that penetrated about 3.1 miles/5 kilometers into the shallow crust (shown in yellow). Wind and small explosions (shown in blue) create shorter pressure waves that only penetrate down about 328 feet/100 meters.

The waveforms of the ground motion recording and the pressure sensor recording from a station with both types of instruments (see second image above) match up, indicating that the pressure waves are causing the ground (crust) to deflect.
