In the meantime a powerful earthquake a few hours ago.
Hitting the Southern California coast and off the western coast of Mexico here six point three magnitude about 2:30 AM local time.
About 530 here on the East Coast that a 160 miles off the coast of San Diego here and local news reports say the folks in Long Beach and Newport Beach.
In Southern California they felt the shaking.
Doctor Johnny was -- size mileage is director of the western observatory department of earth and environmental sciences at Boston College -- good morning to you doctor.
-- -- some interesting things to our producers that the interest in thing about this earthquake is the location where it occurred.
How so that's were.
That's right -- all of the earthquake activity we've seen off -- Southern California.
Has -- on the continent itself.
This earthquake occurred in the rock where the Condit is dropped away and now we have purely Oceanic rock.
Very unusual for earthquakes in Southern California -- -- show folks the San Andreas Fault I think that's what a lot of people think about in California.
I just advance -- one if we could hear we'll show how it how it runs along the entire West Coast of California what you're saying sir.
It is that whether or not the onshore activity is related to the offshore activity can you make a connection -- Or not.
Well will be studying that we don't really know.
What we know is obviously the Pacific Ocean plate is moving relative to the North American plate.
The San Andreas in the other faults are the boundary.
Now all of the defamation is on the falter on either side of the fault.
The question for us is is their son did play defamation is taking place now in the Oceanic rock to the west of California.
Could that pose a threat of earthquakes or even Sanaa and does that help us -- better predict the next big one.
It could help us predict and the next big one if we see unusual depth formations offshore.
That also are associated with earthquakes.
Onshore.
So far I don't know of any unusual onshore earthquake activity or interest in thank you doctor doctor -- -- there at Boston colors there -- Newton Massachusetts.
No tsunami on this one.
Because this magnitude was not big enough to create one but the depth is interest in two.
Only about six miles which is relatively shallow sir thank -- calling you again doctor.
