Do Earthquakes Happen Under Mountains ?
« Reply #25 on: 20/09/2007 05:45:40 »
a few years back we had a 7.2 and 7.0 and other 4 and 5 point aftershocks .. Those were really amazing. 1rst one knocked me over off balance while vacuuming the floor. I thought I did it hitting my cabinet with the vacuuming.. LOL The only problem with that was that I was not a drinker so I realizes after several seconds we were having a big quake . I had time to get out of the house and watch things on the street sway and move telephone poles cars trucks rolling back and forth and huge waves of the paved street rolling along like ocean waves, actually humping up and straightening out! LOL! Was creepy!
Must have been an amazing sight.  I've often thought I'd like to see something like that-but when it comes right down to it I'd probably be as scared as everyone else.
Karen, what town do you live in?  That way I can look on some of my fault maps and see if I can provide any further info.

However, there are no earthquakes on Mars (nor has there ever been an earthquake on Mars)!

I thought the jury was still out as to whether there had been earthquakes (or should that be marsquakes) in the dim and distant past of Mars.

You are living just north of Mendocino Tripple junction- where three different tectonic plates come together.  Pacific plate, North American plate and the Juan de Fuca plate.  You've got it all!
No wonder you have so many earthquakes.  You've got 2 major transform faults (San Andreas and Mendeoino), you live right on top of a subduction zone and have a spreading center not far offshore.  No telling how many subsidary faults?
I'll try to pull together some maps and get them back to you in the next few days.

I tried to doctor up a Google Earth image?



MF is Mendocino transform fault, SAF is San Andreas fault, SZ is subduction zone (Juan de Fuca plate is diving beneath the NA plate), spreading ridge shown on western edge of Juan de Fuca plate.

Hee hee You did it right.. I have never heard the term "duece of a time" what does it mean the term duece in this case.. I know like hell of a time, but just duece used what does it mean. I always thought it was the 2 in a deck of cards?

Duece coup- would have been my dream car at one time.  I always drove practical cars, like the beat up old international Scout I ran around the hills in- thing was built like a tank, woefully underpowered, but would go anywhere.
