Whole cluster of quakes near Lake Almanor, odd.

12 quakes in that area last hour ranging from 2.5 to 5.7. 44 total if including lower than 2.5 magnitude Wonder if this is related to Mt. Lassen magma pool? Mt. Lassen is just 30mi to NW.

49 quakes now, note distance from cluster to Mt. Lassen. http://earthquake.usgs.gov/earthquakes/map/

Cars in water after bridge collapse on I-5 north of Seattle
Posted: Thursday, May 23, 2013 8:39 pm | Updated: 8:57 pm, Thu May 23, 2013.
MOUNT VERNON, Wash. – The Washington State Patrol is reporting that cars and some people are in the Skagit River this evening, and authorities are halting traffic after the Interstate 5 bridge between Mount Vernon and Burlington collapsed, reports the Skagit Valley Herald, the Idaho Press-Tribune’s sister paper.
…

Coincidence? Janice Moore reported at 7:31 WordPress-time (Pacific standard, not daylight?) she just heard it on the police scanner.
Now an earthquake at in California just a little bit later. Instantaneously later on geological times.
Could the earth in Seattle have moved enough to take down the bridge, which by the pic was just a section of it? How far does it have to separate at an expansion joint until the sections un-lap and a piece drops out?

Based on the fact that my Facebook page just exploded with posts about the quake… I feel safe to say I am the only person in Sacramento that did not feel the quake

Didn’t feel it in Oakland, and it’s a travesty I that couldn’t measure the tremors.
They’re clearly hiding down in the Hayward Fault.

Solar question:
The primary memory unit remembers previous conversations here, where it was argued about a possible connection between strong solar periods and seismic events. But the actual numbers showed a negative correlation, seismic events were more likely during weak sun periods.
That was before the reconsidering of the sunspot counts and the eliminating of the modern-era Grand Solar Maximum.
Does the weak sun with strong seismic correlation still hold?

Lots on proposed fracking in that area. Did it ever start?
