New Zealand Rocked by 4.9 Magnitude Quakes

Safety fences are erected around fallen bricks on Madras Street in central Christchurch, New Zealand, on Sunday, after a series of aftershocks.
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.
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

Map of the 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.

5.4-Magnitude Quake Shakes Puerto Rico

San Juan - A 5.4-magnitude earthquake struck the U.S. Caribbean territory on Christmas Eve, rattling windows and doors across the island but causing no major damage, officials said.

The quake occurred at a depth of 63 miles south-southwest of the capital of San Juan, according to the U.S. Geological Survey.

Blanca Saez, Ports Authority spokeswoman, told the Associated Press that the international airport is operating as usual. She said six ceiling panels fell at the American Airlines terminal, but that no one was injured.

The earthquake was centered just a couple of miles from the central mountain town of Aguas Buenas.

Emergency officials and police told local media that no damage or injuries have been reported.

Heriberto Sauri, emergency management director, told El Nuevo Dia newspaper that crews would inspect buildings at daylight if necessary.

Rhine-Main region shaken by earthquake

rhine city
Residents of the Rhine-Main region west of Frankfurt were shaken by an earthquake early Thursday morning that scientists say registered 3.5 on the Richter scale.

While such a magnitude is rated as "minor" on the Richter scale, the quake seized the attention of experts because it reached a strength that is very rare for the area.

Residents of the Wiesbaden and Mainz were startled by the deep rumbling that one observer likened to "a train or a truck were driving past the house."

Another observer compared the noise of the quake to "a railway train ... approaching," followed by a dull boom.

The quake occurred at 2:36 am and lasted a few seconds.
