We just had an Earthquake

[Stephanie]

I doubt that Rainband. We have NEXRAD about 8 miles to the north of Atlantic City. The last two summers, there's been an aircraft show right over the beach and those fighter planes fly right over the buildings ( and between them ). There's sonic booms, but it doesn't feel like an earthquake.

[Rainband]

It was felt as far north as orlando and south to sarasota

Sonic booms sometimes register on seismographs, however, the one that occurred here in Charleston, SC last year never registered on over 18 seismic sensors and was NOT reported to be an earthquake/microquake ...

IMHO, the Tampa area had a bonafide tremor ...

Sorry but it was more than a yawn being I am 40 miles from Tampa and my house trembled

I don't think a house would tremble at a 2.7. Even in the 4.9 here two years ago, right by the epicenter was some windows broken and houses shaking, this was much weaker than that.

I wonder if it wasn't something more...

Edit: 5 km is pretty shallow... that may be why the effects felt sound worse than a normal 2.7

I am telling you I heard the shuttle enter the atmosphere more times then I can remember no f-18 could be louder

I agree - a sonic boom is SO very quick - I grew up hearing
them, daily, during the Viet Nam war. I would think that the
ground rumbling would be quite different.

I'm not disputing the earthquake geez... and I'm not disputing your house trembled. It's just I didn't think a 2.7 would be felt outside of a very minor rattling of windows.

Back in 1997 there was a magnitude 3 quake 17 miles away from my town in North Texas

[Rainband]

They said it was a sonic boom now. Case closed I guess

[Brent]

It's back to undetermined magnitude now...

All that arguing over nothing.

I found a 2.7 causing what you described to be a little unbelievable.

Largest I've been in was the 6.8 Nisqually on 2/28/01. It was fairly deep, but it really shook hard and more than enough to get my attention. I think I was roughly 30 miles from the epicenter.

I find it hard to believe that a Sonic Boom would trip seismologic equipment (im surprised fla has such sensors) and indicate a 2.7 quake. I have heard sonic booms and they shake the house and scare you to death. But never the actual earth itself. Also a quake last longer than a sonic boom.

Weird!

I guess it was a sonic boom...

Seminole resident Henry Remi walked outside when he heard what sounded like a series of loud explosions Friday evening.

His neighbor had done the same thing.

"You hear that?" Remi asked.

"Yeah, I heard it," replied the neighbor.

Remi said he wanted to make sure he wasn't losing his mind. He wasn't.

What Remi and thousands of other residents from Citrus to Manatee counties heard and felt was two F-18 jets breaking the sound barrier. The resulting booms resonated from Citrus to Manatee counties.

The two Navy F-18 Hornets arrived from a naval air station in Pensacola and landed about 8 p.m., said Air Force 2nd Lt. Larry Vanderoord, spokesman for MacDill Air Force Base. He called their arrival a "routine landing" and said these planes usually fly faster and lower than typical planes landing at MacDill.

The jets, based out of California, were scheduled to take off again today or Sunday.

"They are very fast, and when they come in, they're very loud," Vanderoord said.

The shaking registered on the U.S. Geological Survey seismograph in Orlando, measuring 2.7 on the Richter Scale, the equivalent of a weak earthquake. Central Florida is not an active earthquake area, said USGS duty officer Madeleine Zirbes.

"They did see it register," Zirbes said from Denver, Colo. "They thought immediately that it could be a sonic boom."

The blast prompted hundreds of calls to area newspapers, TV and radio stations and local authorities. Many residents headed outside to find out why their homes were shaking.

Remi has heard the double boom that comes when space shuttles re-enter the atmosphere. On Friday, he said it sounded more like five or six booms in a row.

"I never heard so many booms come as rapidly as that," he said.

Carrollwood resident Mark Thatcher heard the rumbling over the noise of his television set.

"It just sounded like an airplane really close," he said.
