Exceedingly Rare Indiana Earthquake Felt In Chicago

An exceedingly rare earthquake struck central Indiana Thursday morning, and some Chicagoans felt tremors.

Image
The 3.8-magnitude earthquake was centered about 15 miles east-southeast of Kokomo, Ind. and about 50 miles north-northeast of Indianapolis, and was felt around 6:55 a.m. Chicago time.

The epicenter was five miles southeast of the rural town of Greentown in Howard County, Ind.

John Steinmetz of the Indiana Geological Survey said there have only been two earthquakes of equal or greater magnitude in central Indiana in the past 175 years.

Comment: The Sott editors received an e-mail today from a reader who lives near the epicenter of the earthquake:

Having recently re-read "Secret History" and Laura's series on comets and asteroids I thought you might be interested.

We live approx. 20 miles from what is being described of the epicenter of the small ( initial news reports placed it at 4.2 and then dropped it to 3.8 ) earthquake in central Indiana at about 7:55 this morning, 12/30/10.

The "quake" was immediately preceded ( approx. 3 to 4 seconds ) by the sound of an explosion. My wife and several others, according to reports on local news stations thought something had either exploded,run in to or fallen on their homes. Our trash service was in front of our house at the time and my wife thought maybe the truck had somehow hit our house and as she went to check the shaking started. Having read Laura's work I just thought this might be of interest to the SOTT team. Feel free to contact me if you have any questions.

Thanks for your time,

Small Earthquake Hits Near Central Oregon

A small earthquake has struck in central Oregon.

The U.S. Geological Survey says a 3.6-magnitude temblor struck at 1:17 a.m. Thursday and was centered near the town of Maupin, about 90 southeast of Portland.

The USGS website showed that the quake's intensity was light and very few people reported feeling it.

Quakes of this magnitude rarely cause any problems.

New Zealand Rocked by 4.9 Magnitude Quakes

Masonry and glass rained down near post-Christmas shoppers as a magnitude 4.9 earthquake rocked Christchurch on New Zealand's South Island on Sunday.

No one was injured, but at least 20 buildings in the city's center were damaged by the quake, which scientists said was the latest of hundreds of aftershocks since a 7.1 magnitude earthquake struck Christchurch on Sept. 4. That quake caused extensive damage and a handful of injuries, but no deaths.

Sunday's earthquake also came a few hours after a magnitude 7.3 earthquake struck under the sea near Vanuatu. There were no reports of damage or injuries from that quake, though it generated a small tsunami wave.

New Zealand and Vanuatu are situated on the Pacific "ring of fire" - an arc of earthquake and volcanic zones stretching from Chile in South America through Alaska and down through the South Pacific.

Vanuatu: 7.3 Magnitude Quake Triggers Pacific Tsunami on Disaster Anniversary

A powerful 7.3-magnitude earthquake struck off the western Pacific nation of Vanuatu on Sunday, triggering a small tsunami exactly six years after giant waves killed 220,000 people around the Indian Ocean.

The Hawaii-based Pacific Tsunami Warning Center said the shallow quake generated a tsunami, but it cancelled a regional warning after the wave measured only 15 centimetres (six inches) higher than normal in Vanuatu.

"Sea level readings confirm that a tsunami was generated," the centre said in its bulletin.

"This tsunami may have been destructive along coastlines of the region near the earthquake epicentre," it said, but cancelled the warning when no destructive wave hit.

The quake struck at 12:16 am on Sunday (1316 GMT Saturday), and the initial tsunami warning covered Vanuatu, Fiji and the French Pacific territory of New Caledonia. There were no reports of damage or casualties.

Odd Earthquakes Not Letting Up In Central Arkansas

New Madrid Seismic Zone

Central Arkansas has been hit with a series of earthquakes recently, more than 500 since September 20.

According to the U.S. Geological Survey (USGS), most were hardly noticeable but one stood out prominently when it hit the Richter scale at a 4.0 on October 11.

Geologists can't say whether the quakes will end anytime soon.

Dr. Horton of the University of Memphis feels that the ample amount of earthquakes in this state is quite unusual.

"In the New Madrid Seismic Zone there's approximately 200 per year, so if we had that many in Central Arkansas in less than a month, something is going on," Dr. Horton told CNN's Sarah Hoye.

The problem is that part of central Arkansas isn't even part of the New Madrid Fault Zone, so researchers are trying to figure out what's causing all those earthquakes.
