-- our let's a little bit more insight into the seriousness.
And some precedents for earthquakes in the northeast that we're joined by telephone by the US Geological Survey.
Geo physicist Gavin -- Hi -- welcome thanks for joining us.
I think is joining us this hour kind of -- go and give me a sense of how unprecedented or -- -- this is here in the northeast -- if you could compare the experience we had here verses.
What goes on in the ring of fire obviously just a couple of months outside that devastation tried Japanese earthquake and tsunami.
Sure be my pleasure and we know that be a -- happen in east and eastern Virginia.
Decent Virginia seismic zone it's not just says domestic United States and how the F correctly recorded.
What over the country and indeed indeed globally we know historically either of that has been Preston's for earthquakes.
In -- -- in the cost.
And in 1997 there was an earthquake of about 95 point six have been several -- -- five eleven earthquakes over the past hundred years or so.
And more recent name nothing nothing larger -- about 94 and a half.
With this unexpected.
And also explained the fault.
Situation in the northeast because again using my own reference my personal reference to Southern California we know to fear.
-- -- the San Andreas Fault it's so vulnerable.
What are the fault lines like -- here and you know He gives a little bit more of a scientific explanation of what happened and what type of earthquake this last.
Sure obviously the folks in -- the United States rolled.
On the generally a lot smaller the dissenting Driscoll a plate boundary folks with with far away here and he's from -- from plate boundary folks.
And so cities -- they.
They won't recur of a much longer time scales and they tend to be a lot smaller than those that that would experience and California.
-- the prototype boundaries around around the Pacific that being being far away from from the east we know that the folk of this have -- -- on was a thrust type folks.
And so associated with some some -- -- have strain over long periods of time.
Out there in the -- and he's managing -- Isaacson.
Gavin I'm told that that the rock foundations.
On which heard our soil is build your -- north he's very different from California.
Where they because it's its older more solid rock -- vibrations can extend further is that true.
That that's does precise each earthquakes in eastern United States will be -- over much not a much broader distances and that's why we're having reports have.
This of -- felt.
Down in south -- as South Carolina and Tennessee and office fund all of this Connecticut.
And that the earthquake energy just travels much longer distances in the east and it does say in the west United States yeah unease thank you very much -- for.
