This happens every year about this time and for the life of me I can’t figure out what it is.
A microearthquake occurred at 4:37:54 AM (PST) on Saturday, March 1, 2003. The magnitude 1.7 event occurred 20 km (12 miles) ESE of Yosemite Village, CA. The hypocentral depth is 8 km ( 5 miles).
There’s nothing volcanic in the area it’s taking place and it’s miles from Badger Pass Ski Resort. The topo map at TopoZone shows it to be out in the middle of the wilderness. Only thing I can figure is maybe an avalanche or frost heaving causing exfoliation. Also of note, it is on Red Peak along a MAJOR trail.
