Powerful Quake Strikes E Coast of Honshu Japan

Posted by feww on March 14, 2010

More Powerful Quakes May Be Imminent in Japan Region

Powerful quake measuring up to 7.0Mw strikes the east coast of Honshu, Japan

An earthquake measuring up to 7.0Mwstruck offshore the east coast of Japan’s main island Honshu, about 285 km northeast of Tokyo Japan, located at 37.7N, 141.9E. The quake struck at a depth of about 40km on March 14, 2010 at 08:08UTC.

Another shock measuring up to 6.0 occurred in the same area about 30 km southwest of today’s event some 21 hours earlier.

The quake was reported as a 6.6 magnitude shock by USGS/EHP.

Tsunami Status

According to Japan Meteorological Agency there was no tsunami threat as a result of the shock.

The quake was the 10th powerful (or strong) earthquake (of a possible series of 14) that has struck Japan since August 2009.

Large Swarm of Quakes Strike Near Honshu, Japan

Posted by feww on December 17, 2009

Earthquake Measuring M5.3 Strikes Eastern Honshu, Japan

The earthquake was preceded by a large swarm of smaller quakes which began striking SSW of Tokyo, near the south coast of Honshu, early Thursday Japan time.

JMA has recorded about 5 dozen quakes measuring 2.0 to 5.3 Mw in the Izu-Hanto region. It appears that submarine volcanic eruptions may be occurring.

The northern Izu Island arc is a tectonically active region, where several destructive interplate [and intraplate] earthquakes, severe earthquake swarms and volcanic eruptions have previously occurred.

Earthquake Forecast: Tokyo, Japan

Posted by feww on May 18, 2009

Details of Forecast

Magnitude: 7.8 or larger
Estimated Date:  June 14, 2009 [Uncertainty T+ 60 days]
Epicenter: 35.56°N,  139.98ºE
Location: Tokyo Bay, Tokyo, Japan
Depth: 8km [Uncertainty: +/- 2.4km]
Distances:

  • 8 km south of Tokyo Disneyland
  • 12 km SE of Imperial Palace
  • 14 km WSW of Chiba City
  • 19 km NE of Yokohama

Horizontal Uncertainty: +/- 3.8 km
Probability of Occurrence: 0.8

Note: This forecast does NOT preclude the possibility of other seismic events in the area at any time.

Tokyo Bay Quake Forecast
Map sourced from USGS [National Geographic Magazine – 2002 ] Image may be subject to copyright.

TOKYO and its outlying cities are home to almost one-quarter of Japan’s 127 million people. Tokyo dominates Japan’s politics, arts, finance, trade, and communications, and accounts for a third of its wealth. Eighty years ago, the region suffered one of the world’s most destructive earthquakes, killing 143,000 people, destroying two-thirds of Tokyo, and all of Yokohama. The earthquake left $68 billion in property damage, ten times that wrought by the 1995 M=6.9 Kobe earthquake. Today, the population of greater Tokyo is six times larger than it was in 1923. To accommodate this growth, about 385 square kilometers of land rimming Tokyo Bay, or about a quarter of the bay, has been reclaimed for urban and industrial use. A repeat of the 1923 M=7.9 Kanto earthquake is estimated to cause 30-60,000 deaths 80-100,000 hospitalized injuries, and total economic losses of $2.1-3.3 trillion, comprised equally of property and business-interruption losses. Insured losses were estimated to be $31-36 billion.

But how likely is a repeat of the Kanto earthquake, or are other types and locations of destructive earthquakes more probable today?  [Source USGS]

UPDATE: The Honshu quake detailed below has been downgraded to a 5.7Mw by USGS.

A Large Mag 6.2 Earthquake Hits Near the East Coast of Honshu, Japan

The following details were provided by USGS Earthquake Hazards Program:

Magnitude: Mw 6.2 [Later downgraded to Mw 5.7]

Date-Time:

  • Wednesday, December 03, 2008 at 23:16:58 UTC
  • Thursday, December 04, 2008 at 08:16:58 AM at epicenter

Location: 38.566°N, 142.762°E

Region: Near the East Coast of Honshu, Japan

Distances:

  • 170 km (105 miles) ENE of Sendai, Honshu, Japan
  • 190 km (120 miles) SE of Morioka, Honshu, Japan
  • 220 km (140 miles) ENE of Fukushima, Honshu, Japan
  • 420 km (260 miles) NE of TOKYO, Japan

[Mainshock was followed by a strong aftershock measuring Mw5.2 located at 38.555°N, 142.840°E, Thursday, December 04, 2008 at 12:10:54 PM time at epicenter.]

Map of MMI contours plotted over population per ˜1 square km (see gray scale bar on top of map). The regions of integer MMI values are separated by the thick contour lines and labeled with Roman numerals. The total population exposure to a given MMI value is obtained by summing the population between the thick contour lines. This total is shown in population exposure table. Overall, the population in this region resides in structures that are a mix of vulnerable and earthquake resistant construction. A magnitude 6.6 earthquake 378 km Northeast of this one struck Niigata, Japan on October 23, 2004 (UTC), with estimated population exposures of 481,000 at intensity IX or greater and 386,000 at intensity VIII, resulting in an estimated 67 fatalities. Recent earthquakes in this area have caused, landslides and fires that may have contributed to losses. USGS

Earthquake Location: USGS

Japan sits atop the Eurasian, Pacific, Philippine and North American tectonic plates whose movements cause numerous earthquakes. The country experiences about 20 percent of the world’s major earthquakes of magnitude 6 or greater.

Did you know?

With an estimated total death toll of 88,072 [as of yesterday, Dec 3, 2008,] this year has seen the second worst number of human casualties caused by earthquakes since 1980. The largest earthquake/ tsunami related casualties for the 29-year period occurred in 2004 with an estimated total of 228,802 deaths.  [The stats are based on USGS data.
