As I scan through the countless earthquakes that have occured recently in and around Yellowstone NP, I find 2 earthquakes that are set apart from the
rest.
Earthquake #1:
1.2 2008/12/30 03:02:08 44.595 -110.318
13.0 K DEPTH 56 km ( 35 mi) SSW of Cooke City-Silver Gate, MT
Earthquake #2 More recent
2.4 2009/01/01 10:12:57 44.325 -110.388
37.0 KM DEPTH 68 km ( 42 mi) ESE of West Yellowstone, MT
These 2 earthquakes are the only 2 recently that have been 10k or more below the earth's surface. With the research I've done, the more spontaneous
random deep quakes that occur, most likely means the plates are solid, and just now beginning to relieve stress and crack due to pressure and trapped
water and steam.
These earthquakes are caused by mineral changes as well, which cause the plate to shrink, and become more dense. Stress builds up, and it pulls the
plate apart. There is also an absence of observable aftershock sequences at these depths. I bet we will see more of these random deep quakes if this
caldera comes to life more and more as the days go by. The more of these we see frequently, could mean the earth is opening up and letting new magma
chambers form below.
