OKLAHOMA GEOLOGICAL SURVEY picks QUAKE in INDONESIA

NOTE:Written in red is "8.2" with an arrow pointing at the low frequency waves in the middle in black,which corresponds to the big quake that hit first Indonesia yesterday.

The LOW FREQUENCY seismograms show mainly surface waves from distant earthquakes. The MEDIUM FREQUENCY seismograms show larger Oklahoma and (some) other North American earthquakes. They also show P and PKP phases from moderate to large distant earthquakes. Finally, they show quarry blasts. These limestone surface mining blasts are mostly in NE Oklahoma, but a few may be in other parts of Oklahoma, or Missouri, or Arkansas, or Kansas. A few of the smaller blasts are from Oklahoma or Kansas coal strip mines.
