Quake activity along the San Andreas fault is picking up

@FBM,

In relation to that undersea volcano near Oregon, you might find this interesting. Where does all that water go? Is it replenishing the aquifers?
http://www.washingtonpost.com/news/morning-mix/wp/2015/05/05/lost-lake-oregons-magical-body-of-water-that-disappears-each-winter/

In the mountains of Oregon — about two hours southeast of Portland — is a mysterious lake. Though a relative pond compared with the Great Lakes of the Midwest, Native Americans called this place “Kwoneksamach,” or “unknown.” After the first European Americans to document their first visit in the 1870s had trouble finding their way, the body of water ended up with a name worthy of Samuel Taylor Coleridge poem or a “Friday the 13th” sequel: “Lost Lake.”

But what’s most mysterious about Lost Lake is that, once a year, it actually gets lost. The lake drains through a hole and disappears.

See the article for the rest of the story.

Wow. I guess there's not much use going fishing there, then.

Ouch. Tsunami warning?

EDIT: I guess not.

Earthquake activity has really been picking up since the big earthquake off the coast of Russia about 10 days ago. I've got a feeling that the San Andreas is going to have a major slip very soon. Might also be some major activity in Alaska too.

Watch the USGS animation from the last 10 days to see what's going on.

Earthquake of Magnitude 6.2 Strikes Off Northern California

By Heather Langan

Nov. 28 (Bloomberg) -- An earthquake of magnitude 6.2 struck off California’s northern coast, the U.S. Geological Survey said in an e-mailed alert.

The temblor struck at 5:43 a.m. local time today, at a depth of 62 miles (100 kilometers), the USGS said. The quake took place 133 miles west of Eureka, California, the monitoring agency said.

AROMAS, Calif. (AP) -- Four small earthquakes struck Central and Southern California early Saturday, but there are no reports of damage or injuries.

The U.S. Geological Survey said a magnitude-4.1 quake hit the Ridgecrest area of Kern County shortly before 1:15 p.m. The same area had a 3.2-magnitude quake at 3 this morning.

Two earthquakes also struck the Salinas Valley along the Central Coast.

A magnitude-3.2 quake hit just before 5 Saturday morning and a second quake of the same magnitude followed two minutes later.

The quakes were centered near the town of Aromas and about 35 miles from San Jose.

A 3.0-magnitude quake struck the same area at about 10:30 Friday night.

The latest tumblor came after an earthquake of magnitude 6.2 struck off California's northern coast about 133 miles west of Eureka Thursday.

Earthquake scientists can't see what is is going on below the surface, and seismic detectors only move when there is a quake, so why should anybody listen to them?

Wrong! where do you get your information? Seismic detectors very minor activity...not just when there's a quake.

, they actually HEAR what is going on, and this is done by uing software that connects several seismic stations together. Thats how we can tell epicenters, hypocenters, magnitudes nd critical angles.
We can also measure the earths core by how signals are attenuated at various stations.

And rgman is correct, seismographs record all sorts of noise including explosions at quarries (or buildings coming down after planes hit em).

One of my old field stations where I was mapping a major aquifer by seismics was set up in a tornado cellar an (not to mention how it picked up tornadoes ina certain radius, but also it could let me know when the 3;$5 M freight train passed through the town. (This was in Tennessee.
Ever wonder why we prefer to use analog data recording for seismic data?

@farmerman,

I have increasingly hearing about new faults being discovered. I took this to mean that most likely the science of finding them has improved. Is this correct?

@hawkeye10,

Also due to massive increases with fracking, there is more activity and more quakes in areas that typically never had quakes. Ask Oklahoma about there hundreds of quakes...they never had. All of this fracking activity is being done in the name of advancement...giving the masses what they want..cheap energy prices.

And the jackass who wrote that article you quoted...what an expert! He can't even use the right word. It's temblor..not tumblor.

@hawkeye10,

we can only see a fault when we hear it move. The increase in worldwide seismic stations allows us to accurately map these things. (AND as rags said, every time we inject fluids into the crust we can mobilize old faults and relieve any stress by getting it moving).

The thing is, almost ALL faults are only in the earths crust. The crust is like the skin of an apple and the rest of the apple is the astheno-mantle-core triple layers.

We sit, like on a lilypad that floats over a lake of fire. (Thought Id make your day a little happier)

@farmerman,

Down here in Paradise....we have sink-holes fun. No quakes. Just every now and then..simply... the ground opens up and swallows a car or a home entirely whole. I saw a video clip of a sink hole that occurred in a lake. that one was amazing...watching trees and bushes disappear.

From what I understand many parts of FL are built up on underwater caves, streams, lagoons, and deposits of crushed seashells and limestone...

"Sinkhole losses have been on the rise the last few years in Florida. According to a report by the state, 211 property insurers responded that claims increased from 2,360 in 2006 to 6,694 in 2010, totaling 24,671 claims. The total dollar amount of those claims was approximately $1.4 billion.

RiskMeter’s Top 10 Sinkhole-Prone Counties in Florida are:
1.Pasco
2.Hernando
3.Hillsborough
4.Marion
5.Pinellas
6.Citrus
7.Polk
8.Orange
9.Seminole
10.Lake

Daniel Munson, founder, RiskMeter.com, said many insurers are under the impression there are just a few counties affected by sinkholes, but in reality there are at least 10."

@Ragman,

There is a lake in Oregon that formed over a lava tube. Every year, when the inflow of water slows enough, the lake virtually disappears down the lava tube until the rains can replenish the water faster than it drains.

I posted about it earlier, here:
