The US Geological Survey reported a magnitude 4.6 quake near Petersville, approximately 86 miles from Mount Spurr, with close to 300,000 residents at risk ...

The rock layers themselves along this fault line are a mixture of different types of rocks. The region the researchers examined is covered by a network of borehole seismometer stations placed ...

The remainder, whatever is left, that's what's sent out as seismic waves." Dry parts of the fault line can get so hot - about 1000 degrees Celsius - that the rock melts.
