The USGS confirmed a small earthquake struck San Diego County Thursday night. The quake struck with a magnitude of 3.3 and at a depth of 7 miles at 11:09 p.m. The epicenter of the earthquake was four miles south-southeast of the Palomar Observatory, 17 miles northeast of Escondido and 39 miles north-northeast of San Diego, according to a computer-generated USGS report.

News stations in the area said they received over a dozen calls from concerned viewers who described the earthquake as very loud and said it was accompanied by three eerie booms. There were also reports of violent shaking. No injuries or damage was reported the tremor. No one in our generation remembers so many small tremors across the world triggering so many sonic booms. One has to wonder what is happening in the earth beneath our feet.

Clintonville residents shaken once again by mysterious booms

Clintonville, Wisconsin - Residents are shaken by booms once again in a small Wisconsin city where a small earthquake was recorded last week. Clintonville police say they received 65 calls Tuesday night between 10:35 and 11:40 from residents who experienced the booming. The city has been relatively quiet lately after the booms awakened residents for several days early last week.

The U.S. Geological Survey said a 1.5-magnitude earthquake struck March 20 in Clintonville, a town of about 4,600 people about 40 miles west of Green Bay.

City administrator Lisa Kuss says she has again contacted the Geological Survey about the latest booms.

Magnitude 7.2 Earthquake Hits Central Chile

Santiago feels effects of 7.2 tremor with emergency agency evacuating some coastal areas, although tsunamis not expected

A magnitude 7.2 earthquake hit central Chile on Sunday, shaking buildings in the capital Santiago and the government emergency agency, ONEMI, said it was preventively evacuating some areas of the coast.

The quake struck 64 miles (103 km) west north west of the town of Talca at a depth of 6.2 miles (10 km), the US Geological Survey said.

Magnitude 7.0 quakes or greater are capable of causing widespread, heavy damage.

ONEMI said, however, that the quake was not expected to generate a tsunami off the coast.

The latest earthquake hit near the same central region that struck by a massive 8.8 magnitude earthquake in 2010 and tsnunamis in 2010 that killed about 500 people.

The central area is home to some important copper mines, but the bulk of output in the world's top copper exporting nation is concentrated in the far northern region.

6.1-strong earthquake considered the biggest in Australia in 15 years

The earthquake's epicentre was recorded at shallow depth near Ernabella, 415km north west of Coober Pedy and about 320km south west of Alice Springs, just before 8pm yesterday.

Geoscience Australia reported the quake could have been felt by people up to 500km away and damage experienced within a 40km radius of the epicentre.

Geoscience Australia seismologist David Jepsen said the quake was the biggest in Australia in 15 years.

''There are a number of Aboriginal communities near the epicentre and they would have felt the earthquake strongly,'' he said.

''It is possible there could be some minor damage up there. One of these in a major city would be a different story.

''People as far north as Alice Springs and as far south as Coober Pedy and Oodnadatta could have felt this.''

Micro-quake near Wisconsin city bothered by booms

Federal geologists say a minor earthquake occurred this week near the Wisconsin city where researchers have been investigating a series of unexplained booming sounds. The U.S. Geological Survey said Thursday the 1.5 magnitude earthquake struck Tuesday just after midnight in the eastern Wisconsin city of Clintonville.

Geophysicist Paul Caruso says loud booming noises have been known to accompany earthquakes. He says it's possible the mysterious sounds are linked to the quake.

City officials have been seeking answers related to the late-night booms, which started Sunday night and have as yet defied explanation.

Strange noise in Clintonville: Engineering firm hired to try to find epicenter of loud, booming shakes

Officials have tried to record a series of mysterious booming sounds that have roused residents from their beds in the past few days, but their attempts have come up empty.

City administrator Lisa Kuss, addressing a crowd of about 400 people Wednesday night at a public hearing to talk about the phenomenon, said the city will spend $7,000 to hire Waukesha-based engineering firm Ruekert & Mielke, which will place four seismometers around the city to try to locate the epicenter of the strange sounds.

If the firm finds the epicenter, the next step will be to pinpoint the depth and what is causing it. The cause is likely only a couple hundred feet under the earth's surface, Kuss said.

"It's possible we'll never have a definitive answer," Kuss told the audience at the Clintonville High School auditorium.

The big shakes have elicited big attention and the room was lined with media, including reporters from CNN, NBC and a photographer taking photos for the New York Times.
