Another aftershock in Chile 6.5

Those poor people.

1. Still? Wow.

When does it quit being "aftershocks" and become another earthquake?

[Edweird]

2. That was my first thought as well.

3. I read that it's a month to six weeks

after the quake. There was one last week over 7. I couldn't survive that.

5. You must start to wonder if it will ever end.

Terrible.

6. They're all earthquakes, aren't they?

It's a semantic label that we attach to relate the events, but each one is an earthquake in its own right.

7. Yeah, I know. I just wonder when it quits being an aftershock.

I guess if they are all related to that certain earthquake... I don't know.

8. Looks that way...if they're all on the same fault plane

Apparently they have mathematical models to determine how the intensity of aftershocks diminishes over time...Omori's law (I just did a quick Google).

I guess all the tremors after the big one that occur on the same fault plane will keep being labeled as aftershocks until a new big one (bigger than the first one) comes along. Then, the first big one becomes a "foreshock," etc. etc. Rather confusing, if you ask me.
