How many earthquakes for California in the past two weeks?

[shance]

Someone said four.

[earth mom]

1. I think it was 4 too...

I am feeling REALLY uneasy and vulnerable about it because I live on the West Coast....and I can't help but think it's MIHOP.

ANYTHING is possible with the BFEE in charge... :tinfoilhat:

2. main events or aftershocks?

I mean if you go for aftershocks plenty

Tehy just reported on yet another in riverside, 4.somethng, and this time somebody actually got hurt....

[shance]

3. Quakes and aftershocks are essentially the same thing as far as

cause and effect are concerned, or atleast from a human's existence on the surface level.

they are both movements in the plates and or movements on our surface.

The end result is often very much the same, so in a sense main events and aftershocks are essentially irrelevant.

They both can be significant shifts and create quakes at the earth's surface.

What defines either, I don't know and again, the end result can often be the same.

4. Aftershocks are less strong

even if both are releasing energy

Geologists do distingish in theory between main events, aftershocks and the less common fore shocks... waht worries me is that we may be seeing a series of foreshocks, and I hope we are not

5. We have had 4 since Sunday

Two big ones in Northern California and two good size ones near where I live in Riverside. We had a small one about an hour before the one Thursday afternoon a 3.2. God is pissed at us having a Cyborg as Governor.

6. So how often has this happened in California's history?

8. Many Hundreds

Almost 900 in the past week.

This map is from earlier today:

Apparently this many is unusually high, but not rare. For the past couple of years it's typically been more like 300 a week.

9. I would think this is unusual.

I know small insignificant quakes will happen more frequently but does anyone know how frequently?

[longship]

10. Daily. They happen all the time

We don't often feel quakes that are Richter 1.x or 2.x

Occasionally one will jiggle, but in the past seven years since I moved here I've only felt three big ones--two in the past week!
