California be prepared for the big one, get ready!

I won’t believe it was an earthquake until a Climate Change Scientist reviews it.

That’s a really deep quake and those deep ones are less likely to produce a tsunami. Some quakes don’t uplift if a side to side quake. I’ve been wondering a bit if we might see a de jávù of 2008 since we have the big volcano eruption in Chile similar to Chaiten. A bit larger, actually. Remember Okmok & Redoubt followed Chaiten as did Shiveluch & Kosatochi. There have been some up to 6km plumes coming from Kamchatka the last few weeks. That would be big news anywhere else.
That’s interesting. No one at my house near Anchorage felt it. Good to see no tsunami threat.
It appears that this entire fault-line is “walking”. How long before there is a big one in San Francisco?
Earthquake down below…asteroid up above…not a lotta choices should Ma Nature decide to shake a few fleas off of her back, eh?
This is what happens when you have too much ice melting, and all that water and weight displaced!

Expect more of the same 27th June-July 2nd
Piers has been right so far.

There was a 6.7 in northern Japan yesterday.
June 23, 2011, Hachinohe, Japan, earthquake, 6.7 magnitude

HeyZeus! That’s a rough day in the northern pacific. Gotta be those poly bears trying to attract more geo-paleo-meteo-seismic funding. Sneaky Ursines….don’t tell the penguins….they’re even craftier.
Long, flat…and then…quake.
I keep hoping Mann will explain it all.
Christchurch New Zealand is still getting shocks, up to 5.7, I think there have been 7,000 aftershocks higher than 3 since September so far. Most of the central city is written off, and several suburbs, 5,000 homes, have been condemned as unsafe, due to either structural damage or unstable ground and liquefaction dangers.
A new fault line opened last week, to the east of the previous one.

Over at Grist they have mashed isostasy/eustacy into meaningless constructs by masticating on the idea of sea level rise causing earthquakes, while ignoring tides, both marine and earth, happening twice a day. Woe be to the Grist Bay of Fundy, as the crust explodeth forth.
That one (Hachinohe) woke me up. Ah! time to get up, put on the kettle and make a pot of tea. I’ve become quite sensitised to earthquakes in recent months.
“A high speed stream from CH457 became the dominant solar wind source after noon. There was a sudden change in solar wind parameters at SOHO at 02:18 GMT on June 23, maybe the arrival of the CME observed on June 21″

CH459 is now Earth-facing…

More to come???
It looks like the “ring of fire” around the Pacific is getting a good work out this past 12 months. In Christchurch NZ they have had approx 7000 quakes ( or aftershocks ) –that is not a typo — since the first big one in Sept 2010.
There have been more quakes in Christchurch, NZ, also. Lots of activity along the rim.

Can anyone point me at a good reference that explains the physical mechanism linking solar and seismic activity? I keep reading that there is a link but for the life of me I can’t imagine how it would work. Thanks.
Daily record (115 days and 1060 earthquakes later) there is no conclusive evidence of a direct link between eqs occurrence and geomagnetic activity, despite two interesting patches which amount to ~ 50% of the current record (7 March – 4 April and 15 April -15 May) Degree of certainty is still uncertain .

RobB, don’t think there is a known mechanism, just some correlations. The complextiy of techtonics make it unlikely there is one mechanism that would act consistently.
This link shows an a connection.

I think you are forgetting to drink a six-pack first, though I understand some people are to rooted in reality and require more radical preconditioning before being able to understand the link.
Chile, New Zealand, Japan, Alaska ,,,,,,, Cascadia fault next?
Bad news if it is.

It has been very hot this month. Figger that is what dun it.
Looks like the heat also melted down Climate Progress.
The 1946 Pacific tsunami caused damage all the way to Chile. It was a lot shallower earthquake. If my thinkolator isn’t on the blink I remember a deep quake like that before Sarychev Peak in the Kurils exploded in 2009. I hope we don’t have magma cracking rock again.
The 1946 Aleutian Islands earthquake was an earthquake near the Aleutian Islands on April 1, 1946. It was followed by a Pacific-wide tsunami. The earthquake was a magnitude 7.8, with its epicenter at 52.8°N, 163.5°W, and focal depth of 25 km. It resulted in 165 casualties (159 people on Hawaii and six in Alaska) and over $26 million in damages.
Multiple destructive waves at heights ranging from 45 –130 ft occurred. It obliterated the Scotch Cap Lighthouse on Unimak Island, Alaska. among others, and killed all five lighthouse keepers. The wave reached Kauai 4.5 hours after the quake, and Hilo 4.9 hours later. This prompted the creation of the Seismic Sea Wave Warning System, which later became the Pacific Tsunami Warning Center in 1949. [1]
The tsunami was unusually powerful for the size of the earthquake; it was the last time any earthquake below magnitude 9.0 caused tsunami fatalities far from the earthquake area. Scientists think the tsunami may have been caused by an earthquake triggering an underwater landslide.

Sorry, I can’t make out any shaking of the buildings because the camera is shaking too much.
