BREAKING: 5.1 earthquake strikes Delaware, felt in Pennsylvania

A 4.4 magnitude earthquake with an epicenter near Dover, Delaware, has rocked Pennsylvania.
The US Geological Survey initially reported a 5.1 earthquake offshore of Dover, Delaware on Thursday afternoon, but adjusted the magnitude to 4.4 shortly after 5:00pm Eastern time.

A 4.4, that must be the equivalent to a whale fart. Nobody would even know it happened.

Yah..only reason I posted it is because I was at work and heard a whole bunch of people talking about it so thought it was something different.

Im waiting for the EMP or HAARP or North Korea posts to show up.. =)

That's a big quake really, particularly for Delaware. Sure it's not a 6+ but that 4.4 is pretty rare for the area.

Odd area for an earthquake isn't it?

a reply to: opethPA

I think it's pretty news worthy considering the infrequent occasions there

Sure is...

that's what i was thinking...

HAAAAAAAAARP!!!!!!

It looks like the hypocenter was below the Leipsic River delta.

From EMSC, we see that although not highly seismic, the area does occasionally get quakes:



Since 1960^

It's notable, that's all I'd call it. Earthquakes can happen anywhere, even in the middle of plates, it's just more rare.

Ever smelled a whale fart?
















Me neither

Is the epicenter at the AF Base?

My word children, not everything is caused by the U.S. Government or its many black projects. Considering the location the cause of the quake is obvious.

River Dragons....

Wake up Sheeple, they are hungry!

Not far from it, but probably not within the range of uncertainty:



I also just noticed that the number of stations since I linked USGS above has from from 14 to 20, but the uncertainty has increased for location and decreased for depth. As more stations are added (presuming they are still analyzing data, and this being an oddly located quake, I imagine they will), both should become a bit less uncertain.

I couldn't help but think of this when I read your thread title lol.

Didn't feel it. No one I know did either. But I do live to the north in PA by the hump of Delaware. It's maybe a couple of miles away.
But nothing...

Tunnelling. Could be an answer to these quakes and booms and tremors... can anyone form a line for all these events.

Perhaps a high speed tunnel could be being built beneath the americas'... just a thought


I mean, couldn't one just kick one these registers to read an event ?

Does it have to be an earthquake or just a nearby event ?

The instruments don't really record earthquakes, they record vibrations (I don't think that's technically correct but I'm not an expert). Experts analyze the signal and determine what caused it and where, in most cases an earthquake and it's too deep in the earth's crust to be anything else.

In this case it was downgraded to a 4.1, at a depth of 8.1 kilometers. That's over 26,000 feet. That's relatively shallow for an earthquake I believe, but it's still too deep to be anything man-made. We have drilled that deep into the earth before, but only narrow bores for research purposes. The temperatures at that depth are so high it makes it pretty much impossible to do any type of industrial work like drill a tunnel.

So no, the facts don't support this being anything but a small earthquake in an uncommon, though still not suspicious area. Earthquakes do occur in that region occasionally.

Vibrations, exactly..... so why not kick the bastard
