Re: Earthquake in S. California

Is this earthquake just near that main fault line rather than on it?

That one is supposed to erupt every couple of hundred years so if they are right, it's not due for the big one quite yet.

Moment Magnitude.

Seismology has moved on a bit since Richter and Gutenberg's day.

So has any authority publicly announced this particular earthquakes magnitude using that method?

I saw a shot of someones swimming pool earlier and it looked quite choppy, a bit choppier than a fart in the bath would cause for example.

The 7.1 being reported is using the Moment Magnitude scale.

 

Seismologists haven't used the Richter scale for years due to its inaccuracy, particularly in measuring large quakes

Do you have any pictures for comparison ?

This event serves as a wakeup call to residents of densely populated areas, like Los Angeles, that it is only a matter of time before the mighty San Andreas fault blows. A magnitude of 7.0 or higher in Los Angeles would likely cause widespread death and destruction.

@DaveyH  Thank you for the correction. I have just read an interesting article on the difference between the two scales.

We spoke to friends who work in the ICU department of a hospital in the LA area. They were not put on alert but not called in and said things are generally getting back to normal.
