Ever worry about LA Earthquake risk? (Big Bear Lake: vacation, land, location)

Let's see... there have been many large quakes in the winter... that must be earthquake "season." No, wait... there have been many large quakes in the spring... THAT must be earthquake "season." But there have been many large quakes in the summer... that must be earthquake "season." Or is it in the fall, when there have been many large quakes? That must be earthquake "season."
Or maybe, just maybe, those of us who have studied Seismology know that there is no earthquake season!

Incidentally, did it ever occur to you that there is a gap in California because it has less earthquakes than some of the other areas of the ring of fire? For instance, Japan has 10 times the quakes that California has. Alaska also has more than California.

This weather is the calm before the storm. Quake might not be in Cali, but a bigger one is going to hit. I think it's Cali though.

Of course a big one is going to hit. But Seismologists don't know exactly when or where.

I plotted the data out.

Completely random; no correlation.

Cal-Tech has many PhDs who work on this thing every day. They have been asked questions about earthquake correlations since Charles Richter was around (I remember watching his interview on TV after the 1971 quake.)

No correlations.

Good. Someone else with common sense.

To address the posters comment about a seismic gap, that isn't the case. Throughout the majority of the Ring of Fire, there are subduction zone earthquakes. This tectonic setting produces more intense and frequent earthquakes than the tranisitional plate bounderies, which is what happens in Northern Mexico and most of California. The area, as Fleet said, sees less seismic activity in general than neighboring areas, and this is normal. A subduction zone quake on neighboring plates will NOT affect the stress at play between a transitional fault boundery between different plates. Now, if there were some large quakes ocurring in Cali now, I would agree that the risk in the next few days would go up IN Cali, but not just because the world has seen "lots" (although it looks normal to me) of seismic activity...

Earthquakes happen anywhere from 1KM to over 300KM below the Earth's surface, so there is no way they are affected by weather on the surface of the Earth. The temperature at those depths is so intense as well, that whether it is 0 degrees or 100 at the surface would make no difference, I believe it is only the first hundred feet of depth from the surface that sees MINOR temperature fluctuations with the seasons. That is why if you go into a cave, the temperature is near 50 degrees all year round, no matter the location on the planet....

I hope this makes sense. I know you are looking for some sort of link, but trust some of us who have been observing longer and know more about the subject, it is random as far as Science can tell at this time (this just means that we can't predict quakes based on anything scientific). There most likely is some sort of logic behind quakes, stress buildup and dynamics in general, but it is so complex, and if the experts in this field don't have any "secrets" or ways of predicting, I doubt just looking at the planets alignment or weather will be any more accurate than random guessing. For example, it is more likely that the kids throwing pellets with a sling shot at the tiger agitated it more than a micro quake. (SF zoo attack reference).

I used to think that more quakes happened at night, but when looking back, they didn't. It was just the time that I felt them, because I was at rest, in bed, and not doing anything else. Remember, it is always easier to remember events that fit into a belief, and dismiss events that don't.

LOL! That's clever: season / reason. I like it!

It's not believable that you studied anything when you never even heard of earthquake clouds before. Others may buy your bull****, but I don't.

'Big Ones" only happen near the equator. Any one who studied sceismology would know this. A 7 is not a big one. It might be big to the unaware, but it's not a big one.

Earthquake season is fall and winter. And since it's winter, I'll prepare yourselves if you live in Cali.

It's sometimes snows in summer, this doesn't mean its winter. It sometimes rains in winter, (like it has here for the past two days) this doesn't mean its summer. Summer is still summer, winter is still winter and earthquake season is upon us.

I've been over 7800 feet underground. That's over a mile and quarter. The deepest nickel mine in the world. There is a sign that says, welcome to hell" because it's so hot.

Everything is connected. What do you thing controls / creates the weather?

A magnitude 7 may not be a so called "big one," but a mega-thrust subduction 9.2 quake sure as heck is. And as you, kidcanaduh, surely know, in 1964 there was a quake of this magnitude in "equatorial" Alaska.

Guess there's an explination for this "aberration." Probably some bizarre reason about Alaska's susceptibility to hold-over-from-its-recent-equatorial-climate days "big one" earthquakes because of an impending perpetual winter setting down on the far north from global freezing, or something like that. Am I close?

Once upon a time, like 4 billion years ago, all of the landmass on earth was joined together. Over the past 4 billion years it separated and earth's landmass ended up looking like it does. You can imagine how violent the quakes were all over the earth to move about such large masses of land. However, since records were kept, the bulk of the big earthquakes occur near the equator.

Oh, and by the way, Alaska's quake occurred on March 27, six days after the end of earthquake season. It was just slow to arrive, like summer or winter weather is at times.

Oh, yeah, I remember Pangea! Has it really been 4 billion years? They say time flies, but this is ridiculous. I must say, I don't miss the earthquakes from those days, but it was nice to take seasonal vacations to all corners of the land without having to worry about ocean passages and customs agents. Ah, the good old days.
