My Dad’s Backyard Seismograph Setup
Recent went back to my family home and felt y'all might appreciate a home made set up. I grew up watching for earthquakes with my dad.

Since May 9/16:15 Pacific Daylight Savings Time, the earthquake.usgs.gov website has recorded 17 earthquakes in a span of 5 hours. including 4.4 and 4.5 shocks, 1 to 1.4 km NW of Brawley, 32.990°N 115.552°W. It's a fairly active zone along the San Jacinto fault.
(Sorry, haven't yet figured out how to stop my map from taking up a huge amount of space.)
I live in Southern California and we’ve had a significant increase in medium earthquakes.
I’ve learned recently about the Juan de Fuca and Explorer plates are slowly sliding beneath the North American plate. (The tectonic plates located near Washington/ Vancouver Canada coast)
Last year studies indicated Juan de Fuca plate in particular is crumbling apart and there is a 2km ridge or a hole in the tectonic plates between the coast of Vancouver and Seattle.
I’m growing increasingly concerned and I just would like to know what people’s plans are if it happens and how to prepare possibly.
Many earthquakes in Brawley, CA. Has been a very active area.

M2.7&2.9: Two earthquakes hit the area in the last 9 days. Zero the last year and zero within last 10 years within 58 miles of Detroit. Anyone got any opinions on this? Just a random anomally?
