TOKYO —
A 5.7-magnitude earthquake hit eastern Japan on Tuesday morning, seismologists reported. No tsunami alert was issued.

The quake struck at around 4:10 a.m. off the eastern Honshu coastline, 25 kilometers from the city of Toba and 37 kilometers from the city of Ise, according to the U.S. Geological Survey which monitors earthquakes worldwide.

The tremor struck far down at a depth of 332 kilometers, the USGS added. There were no initial reports of damage.

Japan lies on the so-called “Ring of Fire”, a series of seismic fault lines encircling the Pacific Ocean which create frequent seismic and volcanic activity.

A 5.5-magnitude earthquake hit eastern Japan last week, rocking buildings in Tokyo. That tremor struck at a much shallower depth of 59 kilometers.

A 5.3-magnitude earthquake has hit the Japanese prefecture that is home to the nuclear power plant crippled in the March 2011 quake and tsunami.The US Geological Survey said the earthquake struck at 2.25am (17.25 GMT) on Friday at a depth of about 22km under the Fukushima prefecture, about 177km northeast of Tokyo.

The Pacific Tsunami Warning Centre did not issue an alert.

5.9 earthquake strikes Japan off Fukushima coast

An earthquake with a magnitude measured at 5.9 by Japan’s Meteorological Agency has struck the northeast of the country. The epicenter was close to the Fukushima coast and only 200km from Tokyo, causing buildings in the capital to shake.

The quake struck at 2:48 pm (05:48 GMT) in the Pacific Ocean, approximately 50km (31 miles) from land. The United States Geological Survey recorded the earthquake as being of magnitude 6.1, with a depth of 33km (20.5 miles).

No tsunami warning has been issued, despite the offshore quake’s close proximity to Fukushima prefecture, where the magnitude 9.0 quake in March 2011 instigated the Tsunami, which led to the deaths of at least 16,000 people and nuclear meltdown at the Fukushima Daiichi plant.

Tokyo Electric Power Co.’s two nuclear plants in the prefecture reported no immediate irregularities as a result of the quake, according to the local Kyodo news agency.

Miyagi prefecture, further north, suffered the strongest impact from the quake. No information has been released on potential injuries. However, its Onagawa nuclear plant also recorded no irregularities, according to its operator Tohoku Electric Power Co.

“We have received no reports of damage so far,” an official from Fukushima prefecture told AFP.

7.0 Quake Hits Ocean off Japan, Russia; No Damage

ABC NEWS AP PRESS
TOKYO April 19, 2013 (AP)
A 7.0-magnitude earthquake struck in seas off far northern Japan and far eastern Russia on Friday, but no damage was expected.

The Japan Meteorological Agency said sea changes were possible. No tsunami warnings have been issued.

The tremor struck around midday in the Pacific Ocean at a relatively shallow depth of 10 kilometers (6.2 miles). The U.S. Geological Survey measured a stronger 7.2 magnitude.

Japan and Russia both claim some of the sparsely populated islands in the remote region.

The epicenter was 58 kilometers (160 miles) east-northeast of Kuril’sk, Russia, and 528 kilometers (328 miles) northeast of Nemuro, Japan.

The nearest land is the volcanic islands of Urup, Iturup and Sumushir. Hokkaido officials said the islands were not under Japanese control.

The area is about 1,500 kilometers (930 miles) northeast of Tokyo.

6.2-magnitude earthquake strikes off Japanese coast

By the CNN Wire Staff
updated 8:28 PM EDT, Mon October 1, 2012

(CNN) — A 6.2-magnitude earthquake struck off Japan’s eastern coast early Tuesday, the U.S. Geological Survey reported.
With a depth of 9 kilometers (5.6 miles), the tremor was about 96 kilometers (almost 60 miles) east-northeast of Miyako and 550 kilometers (342 miles) north-northeast of Tokyo, according to the U.S. agency.
The quake occurred just over a year and a half since a 9.0-magnitude earthquake triggered a huge tsunami off Japan, resulting in thousands of deaths and the world’s worst nuclear crisis in a quarter century.
The Japan Meteorological Agency, however, did not issue any tsunami warnings or advisories immediately after the Tuesday morning quake, according to its website. No such warnings were issued by the Pacific Tsunami Warning Center either.
A little more than 30 minutes after this first earthquake, another significant, if slightly weaker one, hit the same general area.
This 5.1-magnitude tremor was about the same distance from Tokyo as the first and about 107 kilometers (66 miles) east of Miyako — which was among the areas devastated by the March 2011 earthquake and tsunami — according to the U.S. Geological Survey.
Tuesday’s second quake was much deeper than the first, rooted about 38 kilometers (23.6 miles) below sea level.

Fukushima quake, tsunami disturbed upper atmosphere: NASA

Reuters

WASHINGTON (Reuters) – The massive earthquake and tsunami that hit Fukushima, Japan, last year wreaked havoc in the skies above as well, disturbing electrons in the upper atmosphere, NASA reported.
The waves of energy from the quake and tsunami that were so destructive on the ground reached into the ionosphere, a part of the upper atmosphere that stretches from about 50 to 500 miles above Earth’s surface. READ MORE
