Japan Rocked by Nearly 10,000 Tremors in Quake Aftermath

Sankei via Getty Images(TOKYO) -- As Japan readies to remember the 9.0-magnitude earthquake and resulting tsunami that struck the country exactly a year ago from Sunday, more details are surfacing as to just how active the Earth has been since then.

The Japan Meteorological Agency (JMA) says about 10,000 tremors have rocked Japan since the disasters hit on March 11, 2011.  That's more than eight times the number recorded the year before.

The majority of the tremors -- 70 percent -- were aftershocks from the large quake, according to the agency, but there's also been a notable amount of shaking inland as well.

What's more, the JMA says the tectonic plates underneath Japan continue to shift the country eastward, so more strong quakes are likely.

Last March's earthquake crippled the Fukushima Daiichi nuclear power plant, triggering a nuclear crisis in the country.  Nearly 20,000 people were killed and hundreds of thousands of others were displaced from their homes.

Desperate Search to Find Turkey Earthquake Survivors

ADEM ALTAN/AFP/Getty Images(ISTANBUL, Turkey) -- Aftershocks as strong as magnitude 6.0 rocked Turkey into the night, following a 7.2-magnitude earthquake that hit eastern Turkey earlier Sunday, leveling dozens of buildings and leaving more than 200 people dead.

As many as 100 aftershocks were recorded after the initial temblor, including at least four of magnitude 5.1 or greater throughout the day.

With the death toll expected to climb dramatically, rescuers frantically searched for survivors in Van and Ercis, two of the hardest hit cities near Iran's western border.

Crews are using whatever heavy equipment is available to dig people out from under the rubble with family and friends of victims resorting to using shovels and their own hands to sort through fallen debris.

The quake, which struck the region at 1:41 p.m. local time, was upgraded from a preliminary magnitude of 6.6 to 7.3 magnitude.  The U.S. Geological Survey later revised the magnitude to 7.2.

The depth of the epicenter was considered shallow -- 12.4 miles, shallower than the earthquake that devastated Haiti in January 2010 -- and more potentially destructive, combined with the poor building codes in the region.

Earthquakes and seismic activity are nothing new to Turkey, as the area is riddled with faults, but the USGS said Sunday's quake is the biggest to hit in the region in more than four decades.

Another Strong Aftershock Rocks Japan; Tsunami Warning Issued

Comstock/Thinkstock(TOKYO) -- A 6.6 magnitude aftershock struck Japan Monday, less than one week after another strong earthquake rocked the country and left at least three people dead.

The latest aftershock comes on the one-month anniversary of the March 11 earthquake and tsunami that killed up to 25,000 people.

A three-foot tsunami warning was issued for northeastern Japan following Monday's tremor.  No injuries or damages have yet been reported.

Tokyo Electric Power Co., the company that runs Japan's crippled Fukushima Daiichi nuclear power plant, evacuated its workers following the aftershock and temporarily stopped efforts to cool the plant's reactors.  The company said power had been cut at the plant but no damage or irregularities were reported.

On Thursday, a 7.1 aftershock also hit the country, leaving close to four million people without power.

Japan on Edge After 7.1 Aftershock; At Least Three Dead

Structural damage from the initial 9.0-magnitude earthquake that struck Japan on March 11, 2011. JIJI PRESS/AFP/Getty Images(TOKYO) -- At least three people were killed after a 7.1 earthquake rocked northeast Japan Thursday, knocking out power to millions as the country seeks to rebuild and recover from last month's devastating quake, according to Japanese officials.

Right away, it was clear this wasn't just another aftershock as buildings swayed violently for minutes.  Close to four million people were immediately plunged into darkness as power plants were knocked offline.

Authorities told people near the coastline to evacuate and head to higher ground as a small wave hit the coast 12:40 a.m. local time Friday.  Thursday's quake, which was 25 miles deep, was the strongest aftershock since the 9.0 quake on March 11.

But the greatest concern was for the Fukushima nuclear reactors, where several workers were forced to evacuate.

After midnight in Japan power company officials sought to reassure the public.

"We don't recognize any new leaks so far," a Tokyo Electric Power Company official said, adding that radiation levels remain steady.

The Fukushima Daiichi plant has been on the verge of a meltdown since last month's quake damaged the complex and its cooling system.

At two other facilities, the Onagawa nuclear plant and the Higashidori nuclear plant, the quake caused power outages that forced both onto emergency generators to keep fuel rods safe.  At Onagawa, water from spent fuel rods actually spilled onto the floor but was contained.

Experts monitoring the crisis worry that more strain is being put on reactors that are already overburdened.
