Subject: SoCal storms and earthquakes, a question for others.


I've lived in SoCal most of my life. I have been interested in quakes at least the past 25 of those years.

We've had lots of storms with no felt quakes shortly after.

We've had lots of felt quakes with no recent preceding storms.

So my question for everybody is, how would you determine if there is really a connection between storms and quakes?

Sorry, I meant the year 1970 , like the late fall early winter. Not the
decade. I lived in La Crescenta and remember the Sylmar Quake very
clearly. Sylmar was in Feb of 1971. Sorry for the confusion.

I’m not sure but I remember as a kid severe flooding in maybe the late
1970’s in the big Tujunga River area and I think it was prior to the Sylmar
quake? I remember a cemetery near the Lake View Terrace area having
caskets floating down the streets the flooding was so bad. Not sure if that
helps.

"...severe flooding in maybe the late 1970’s in the big

The Sylmar quake was in 1971, not the late 70's.

Not picking on you, but this is why we can't go by our anecdotal
memories. This is human nature. Memories are not static written
in stone things, unfortunately. I myself have experienced this
with my own recollection of events.

But, yeah, there has been some terrible flooding in Southern
California. But to me, I've never noticed a relationship with
significant earthquakes.

So hence my question to everyone thinking there may be such a
connection. I know how I would try to determine if there was a
relationship. I'm curious how others would do it.

Is it fair to say that because a quake happened after a big rain
that quakes will always happen after big rains? And what about
quakes that don't happen after big rains? I suppose if we make
the window between big rains and quakes long enough, we could
say all quakes happen after big rains. Is that useful?
