OT: What’s up with all the earthquakes?

[Aecetia]

Anyone know what the city of L.A. is built on? Apparently, earthquakes travel rapidly through rock and slowly (doing more damage) through sand. So depending on size of the quake it eventually gets, it could really be devastating. Also, depending on what the quake takes out in the way of infrastructure: freeways, rails and even water, we could be in for a world of hurt because we would not be getting any deliveries unless we start shipping them by boat or flying them in (assuming the runways are not damaged.

My honest two cents on this, having lived through the Northridge and Sylmar quakes, from my experience, you are likely to experience strong aftershocks for two or more years (above 5 points), and in the case of the two above quakes, it did not lead to another major quake.

I’ve lived in California all my life (with the exception of a couple of years overseas), and don’t ever remember a series of earthquakes like this. Anyone else?

I lived through the San Fernando/Sylmar earthquake.. so I have seen much worse.

It looks like we are ‘ok’ since the fault(s) near us are moving fairly easily. I would worry about the Los Angeles basin. There have been some quakes north of Los Angeles and quakes in the Imperial valley down to Baja. The only part that is not really moving is LA. That means pressure is building up over there. Topping it off, the fault-line takes a turn (more like S-bend) through LA. This means that it doesn’t want to ‘slip’ as easily as where the faultline is straight.[/quote]

The quakes we have been feeling have been on the Elsinore fault (blue line) and not the San Andreas (red line).

The Elsinore runs quite a bit closer to San Diego,in fact passing under Julian. It does look like the aftershocks are traveling Northward. Hopefully it will keep going releasing smaller amounts of energy. Somewhat scary to me is that there is a point where the quakes stop. This could be where a significant amount of energy is being stored up for later.

But it does not hurt to be prepared I guess,

Now Katla, that’s something to worry about.
