The magnitude of most earthquakes is measured on the Richter scale, invented by Charles F. Richter in 1934.
Magnitude, Earthquake Effects/Estimated Number Each Year
2.5 or less - Usually not felt, but can be recorded by seismograph/900,000
2.5 to 5.4 - Often felt, but only causes minor damage/ 30,000
5.5 to 6.0 - Slight damage to buildings and other structures/500
6.1 to 6.9 - May cause a lot of damage in highly populated areas. 100
7.0 to 7.9 - Serious damage/20
8.0 or greater - Can totally destroy communities near the epicenter/One every 5 to 10 years
A magnitude 2.8 earthquake hit an area 9 miles west-northwest of Yorktown on Wednesday night.
"I was in bed, and the whole house just shook. It felt like a Mack truck had just run into my house," said Debbie Taylor, 61, of Gillett.
She did not know that the sensation was an earthquake until her sister in Houston called after hearing about it on the news, Taylor said.
"I always thought earthquakes were like a rumble, but this was one big bump. I wouldn't want to feel a 5 if that was a 2.8," Taylor said.
"Everybody I talked to today say they didn't feel anything," Peggy Johnson, Nordheim city secretary, said Thursday.
The epicenter of the quake was about 9 miles west-northwest of Yorktown, said Paul Caruso, a geophysicist at the National Earthquake Information Center in Golden, Colo. A resident reported to the center that it could be felt in Gillett, he said. Gillett is about 10 miles from its epicenter, he said.
"We don't have a lot of earthquakes there. So yeah, it is odd," Caruso said.
