7.4 Earthquake hits Japan!

Japan Earthquake 2011: Magnitude 7.4 Temblor Causes Tsunami Warning

TOKYO — Japan was rattled by a strong aftershock and tsunami warning Thursday night nearly a month after a devastating earthquake and tsunami flattened the northeastern coast.

The Japan meteorological agency issued a tsunami warning for a wave of up to 6 feet (two meters). The warning was issued for a coastal area already torn apart by last month's tsunami, which is believed to have killed some 25,000 people and has sparked an ongoing crisis at a nuclear power plant.

Officials say Thursday's aftershock was a 7.4-magnitude and hit 25 miles (40 kilometers) under the water and off the coast of Miyagi prefecture. The quake that preceded last month's tsunami was a 9.0-magnitude.

Buildings as far away as Tokyo shook for about a minute.

In Ichinoseki, inland from Japan's eastern coast, buildings shook violently, knocking items from shelves and toppling furniture, but there was no heavy damage to the buildings themselves. Immediately after the quake, all power was cut. The city went dark, but cars drove around normally and people assembled in the streets despite the late hour.

U.S. Geological Survey gave the preliminary magnitude as 7.4 and it struck off the eastern coast 60 miles (100 kilometers) from Sendai and 90 miles (140 kilometers) from Fukushima. It was about 215 miles (345 kilometers) from Tokyo.

The depth was 25 miles (40 kilometers). Shallower quakes tend to be more destructive. Hundreds of aftershocks have shaken the northeast region devastated by the March 11 earthquake, but few have been stronger than 7.0. A Pacific Tsunami Warning Center evaluation of the quake said an oceanwide tsunami was not expected.

Why Japan's Massive Earthquake Surprised Scientists
While seismologists expected Japan's next big earthquake to strike near Tokyo, today's major tsunami-creating quake happened out at sea and on a different fault line. Here's why scientists didn't see it coming.

It may be hard to believe, but earthquakes occur daily by the thousands throughout the world. Granted most of these earthquakes are minor trembles, but some can cause an enormous amount of damage.

The earth is enveloped within an upper layer known as the crust. This crust consists of gigantic rock slabs, known as tectonic plates, which occasionally slide past each other or collide. Many of these contacts are unnoticeable to the surface, but when tensions build up, the stress may be released quickly in the form of seismic waves. These vibrations caused by the seismic waves push their way to the surface through hundreds of miles of rock.

According to Tim Flood, professor of geology at St. Norbert College, the situation was not one where the plates were sliding past one another, but rather one of the plates (under Japan) collided with another plate and fell below it at a somewhat diagonal angle. This inequality in the sea floor eventually caused the tsunami.

Interestingly enough, Flood says that earthquakes are absolutely nothing new to our planet. These have been occurring for millions of years and they have developed the sort of physical world we live in today.

Breaking News: Fukushima may be hit again as new 7.4 magnitude earthquake hits Japan


April 7, 2011

Officials at the Japan Meteorological agency have reported a 7.4-magnitude earthquake off the coast of Miyagi prefecture Thursday, also issuing a tsunami warning for a wave of up to one meter.

Japan's NHK television also reported a tsunami advisory for Iwate Prefecture, and said the tsunami could hit the already damaged Fukushima nuclear power complex.
 
A 7.4 magnitude earthquake shook northeast and eastern Japan late on Thursday, and a tsunami warning has been issued for the northeastern coast of Japan, an area badly hit by the March 11 earthquake.
Japan's NHK public television repeatedly said those in areas where the tsunami warnings were issued should evacuate to higher ground.

japan wamekaa ukanda ambo unakuwa frequent hit by earth quake thats why wanapata shida sana hawa wenzetu mwenyezi mungu awasaidie sana.
 
Hii inaonesha kuwa Mungu akiamua hakuna lisilowezekana, binadamu huwa tukiendelea tunasahau kuwa kuna aliyeumba hii dunia na ana maana yake. Kujenga vitu hatarishi kama nyuklia plants kwenye seismic zone ni hatari sana. Nature is uncontrollable.

Oh God have mercy on Japanese.
 
Inasikitisha na kutisha. Nadhani ingekuwa Bongo tayari tungeshajumuisha mambo ya ushirikina!!!
Wengine hasa manambii wa uongo wangesema eti huo ndio mshahara wa zambi kama alivyowahi kusema Mch Lwakatare hapo nyumani kuwa tsunami iliyovikumba visiwa vya huko bara Asia ni matokeo ya dhambi,naona safari hii kakaa kimya
