Ever worry about LA Earthquake risk? (Los Angeles, Whittier: refrigerator, water heater, cabinet)

I agree. As for "it's getting worse" is not a 100% known fact.

We've had 17 ice ages and melts

Right, and it will keep happening with or without humans.

I know it's getting cold in the South Pole.

It is already cold there. It's getting colder.

Earthquake clouds, not lights. I didn't say you could predict anything from them, I just asked if you seen any down there. Watch the skies, they form in Cali all the time.

Haven't seen any. I did see a meteor shower about two weeks ago.

Because something isn't on the news doesn't mean it didn't happen. Remember, Iraq had WMD, Bush and Powel knew where they were, they had sat photos to prove it.

If you want to get into that, U.S., British, Chinese, Russian and U.N. intelligence also said Iraq had WMD (btw, some banned weapons were found). Even Saddam's own Generals believed there were WMD ready to "use."

Dummy, I mean Rummy said the war would be 6 days, 6 weeks or 6 months. That was nearly 5 years ago. Rummy doesn't do quagmires!

I think he meant major combat. And don't forget that Bush said the war against terrorism will take a long time. Because terrorists are all over the world.

There had not been a 8+ quake priot to '05 in years. You would've posted it had there been. You don't have to believe, I'm not trying to convince you.

I didn't post it because the book I was drawing info from was from 1991.

Why do whales and dolphins beach themselves?

Because they are trying to get away from Al Gore.

Is it from sub sonars or is it because of the sounds earth created beneath the ocean floor?

Who knows?

Right, who knows? We don't; but we do know that major earthquakes can (and do) happen any time of the year.

Why were no so few animals killed after the tsunami?

How did they know to head to higher ground but man didn't?

Who knows.

I've been reading about Seismology for around 30 years, including discussions of animals sensing eq's (earthquakes). And, in general, I agree that they probably can sense them.

But I'll probably be back before March 21st to say I told you so. It happens all the time.

You'll be back before March 21st to tell me that there will be more eq's? I already know that!

1906 San Fran. As you pointed out.

It's been 102 years.

Are you trying to say that San Fran. is overdue for an eq? I've known that for years. To be exact, the most overdue area is the Oakland/Berkeley section, the central section of the Hayward fault. The last moderate-or-larger quake was an estimated 7.0 in 1836.

In the Southern San Andreas fault, the most overdue section there is in the Coachella Valley which hasn't had a great (great=8.0 or bigger) since 1680.

1989, '94 and others since '1906 were teasers

I agree about the '89 quake (see above). The '94 quake was "The Big One" for Northridge; it was on an entirely different fault than the San Andreas. (The Oak Ridge, also known as the Frew Fault.) The 1906 San Francisco quake most likely relieved enough pressure so that the next big quake will not be on the section that broke in '06. However, it's still possible the same section can rupture. Scientists just don't know.

Of course there has been...

2 in '94
2 in '95
1 in '96
1 in '98
1 in '00
1 in '01
1 in '03

I figured you would have known that since you claim to know a lot about earthquakes.

Earthquake Hazards Program: Magnitude 8 and Greater Earthquakes since 1990

One thing I learned during the Northridge Earthquake: The power company shuts off power to all areas close to the earthquake instantly. They bring it back up in sections -- when they are able to put all the fire-fighting equipment next to whatever section they are bringing back up.

After the Northridge Earthquake, I was sitting on a kind of peak on Ventura Blvd. and I was able to watch the fire trucks amass around whatever area was going to have power turned back on. It was pretty interesting. Meanwhile, the National Guard was patrolling Ventura Blvd. (Or the California Guard -- or whoever they are.)

Anyway... California=Disaster. I think we've had a lot of experience and we are kind of prepared for a lot of them.

I don't claim to know a lot about quakes. I studied them in 2003 - 2005. I haven't followed it since. But I have a good track record though for a rookie.

Can you name anyone who was calling for a 8+ between November 12 and Christmas Day 2004?

I can. Me. There were actually two. The 8.3 quake on Dec. 23 saw dolphins beach themselves in Oz prior to the quake. The day before, I think it was.

From your link you can see that four 8+ quakes occurred in 2007. That's amazing. I believe the next moderate to major quake in Cali will occur south of Northridge, maybe Huntington Beach area.

Everywhere around the ring of fire has been hit pretty good in the last few years. Cali hasn't. San Fran in '89. Northridge in '94. The next one, I would think, would be lower to on the map to reduce the built up pressure. Interesting topic, nonetheless.

We're discussing global warming in another thread. Here's my take on it.

The Great Warming was made before Katrina. They discuss what would happen to New Orleans if it were hit by a Hurricane. Shortly thereafter, Katrina hit.

Geologists who study the subject point to the Coachella Valley as the most likely location for the next "big one" on the San Andreas fault in the Southern CA area. Though a smaller quake on the Newport-Inglewood fault is often pointed to as being capable of creating much more damage in L.A. proper since it runs directly under the city's west side and south bay.

I've been studying them since the mid-'70s. But instead of reading about predicting them, I read about the "mechanics" of earthquakes, past earthquakes and analyzing data.

Can you name anyone who was calling for a 8+ between November 12 and Christmas Day 2004?

I can't because I don't follow that (reading about those who predict future quakes).

Yep. No doubt it has happened before at times during the long time (millions of years) that the San Andreas fault has existed.

I believe the next moderate to major quake in Cali will occur south of Northridge, maybe Huntington Beach area.

Could be. The next moderate to major quake could also occur in Santa Barbara, Santa Clarita, San Bernardino, Downtown L.A., etc. No one really knows when and where the next big quake in southern California will be. Because there are hundreds of faults in the area. Some of them rupture only every one thousand years; some much more frequently. Some rupture at irregular intervals.

Everywhere around the ring of fire has been hit pretty good in the last few years. Cali hasn't. San Fran in '89. Northridge in '94. The next one, I would think, would be lower to on the map to reduce the built up pressure. Interesting topic, nonetheless

Don't forget the 1999 7.0 magnitude Hector Mine earthquake, out in the California desert.

I've experiences 3 quakes. The biggest a 4.3. It was nothing, but a 4.3 is small, as you know. I wanna be in a big one. I flew to San Fran after the '89 quake hoping to catch an aftershock. No luck though.

Fleet,

You had some excellent points. I like the way you explained and shared your points of view.

I would also like to add that people tend to belive in earthquake myths like "earthquake weather" or season...because we tend to remember the events that fit into these patters and forget the ones that don't.

Same with say pet prediction...my pets never have predicted anything...but I know other people´s animals have acted up...so there is probably something there, if you are right near the epicenter.

I have read a lot about quakes and their mechanisms as well, and what I conclude is that quakes are very unpredictable and usually whenever a predicition is made scientifically, a quake happens in an unexpected area.

I remember the Japanese gov't expected a quake in Tokyo in 1995, then Kobe was hit.

In Socal, a major quake was expected on the San Andreas, but low and behold, the Hector Mine quake ocurred out in the desert, where the local faults were believed to be inactive. Go figure...

Fleet, which quakes have you been through and how have you felt them? I have been through a handful of large subduction zone quakes in Chile and Central America, and they were slower and move sideways...and then I have felt shallow moderate quakes locally and they were very fast and hard.

Big quakes are scary. Those who experience them don't exactly wish for another. Furthermore, if you come through a big quake without much injury or damage, your mind constantly races back to how luck you feel NOT to have been in some other, often familiar, place -- a bridge on the I-5, near a brick chimney at your friend's house, the doctor's office that's now collapsed, driving on the Nimitz' lower deck, etc.
