Quake Watch 2010

Another pretty decent sized earthquake here near Milpitas and Fremont CA. Waiting for USGS to update their numbers. My dogs are going nuts!

Here's the report:

3.8 2010/01/08 11:48:50 37.478N 121.794W 8.1 10 km ( 6 mi) ENE of Milpitas, CA


Same place as yesterday and just a wee bit smaller.

Series of 2.x quakes after:

2.4 2010/01/08 12:36:14 38.408N 122.666W 8.8 6 km ( 3 mi) SE of Santa Rosa, CA
2.5 2010/01/08 12:35:18 38.410N 122.664W 8.7 6 km ( 3 mi) SE of Santa Rosa, CA
2.2 2010/01/08 12:15:33 37.386N 118.830W 10.7 21 km (13 mi) W of Round Valley, CA

I don't make predictions but this is definitely interesting. Take a look at the Cali map:

quake.usgs.gov...

The Round Valley one makes it on to the Long Valley caldera map. (Though just barely)

Another big one in the Solomon Islands

Twitter report of an earthquake in Ulaanbaatar Mongolia (Capital city of Mongolia)

Who knows if it'll ever show up on the USGS map, probably not if it's not large enough. But it's kind of wild how easy it is to get reports worldwide this way now.

It seems like this thread is better served if it just tracks some of the bigger swarms or bigger quakes and not every quake there is. Just my .02 cents after inflation, I'm not trying to take away from anyone's hard work.

Watcher are you also HX3?

[edit on 9-1-2010 by whoshotJR]

I am only mentioning a very small fraction. For example, there are 688 earthquakes currently on the California map alone.

I'm trying to keep it to Mag 4.5 + and one/two posts a day w/ a list unless it's part of a cluster I'm watching. I'd really rather not start another thread about the West Coast of the US (smaller quakes I'm following) since it's much easier to follow from the start. If people would rather I stop I don't have to post here.

I'd prefer to just go back in and edit posts to add to existing lists but can't after the calendar day ends. I'll try to wait until morning local time so I don't end up with two posts for the same day, UTC.


...and I can't help it, I'm intrigued by Twitter earthquake reports (and so is the USGS) for example, there was just an earthquake in Japan about 2 minutes ago, strong enough to wake people up and send them to Twitter. Makes me want to jump on here every time and squeee about it.

It's cool I love EQ's just as much

So are you also HX-3?

I knew there would be a decent one on the west coast eventually with everything popping off. I hope its done but I just have a gut feeling its not.

Here's a map.




Click here for updated map.

It was followed by a 2.7 so that should be a good thing for CA people. Normally that means it wasn't a precursor to a bigger one in the near future.

I am not any other user name. Just quakewatcher. I hope that was all the CA action was about, so far reports of injuries but no fatalities. Could have been much worse.

Hmmm...2 Mi's closer to the surface than the 6.5M...

Watching and wondering if those patterns of 2.x quakes are going to turn into patterns of 3.x quakes... or I am just spooked and have been following this for too long.

Might want to keep an eye on the Keeler area now as well...

I've noticed this area is at the intersection of a couple of nice faults...

I'm wondering if that 3.3M off Oregon yesterday transferred some energy down stream...Hmmm...

Hmmm...getting closer to the surface...

Two earthquakes of struck within minutes of each other on both sides of the Pacific Ocean Saturday night according to reports released by the US Geological Survey (USGS). One quake of magnitude 6.5 was centered about 43 miles away from Ferndale, California, while the other was weaker at magnitude 5.0 and was centered just offshore of the island of Java approximately 60 miles from the city of Tasikmalaya, Java, says the US Geological Survey report.

Now there's major activity North and South in CA. It's an interesting week.

By the way, this was three minutes after the last 4.0 aftershock in the North.

[edit on 10-1-2010 by quakewatcher]

Do you guys think this 6.5 is still a precursor to a larger quake? It's getting pretty interesting over there!
