More quakes this week near Lake Mead
We had a magnitude 2.1 quake at Lake Mead this morning around 7:22 am local time (only half an hour ago as I write this. Monday saw two other similar small events.
I spoke to an engineer with the Bureau of Reclamation last week who said there is a semi-regular schedule of larger releases of water along the river to meet user needs. I've speculated that there seems to be a pattern of small quakes early in the week under and around Lake Mead.
