Strong Earthquake Strikes Near Nishinoshima Volcano

M6.0 quake strikes SSE of Chichi-shima, Japan

Centered at 25.9ºN, 143.4ºE, about 90km SSE of Chichi-shima, the quake occurred at a depth of 10km , according to Japan’s weather agency.

Approximate Distances

• 990km SSE of Katsuura, Japan
• 1,050 SSE of Tokyo

Nishinoshima Volcano (27.247°N, 140.874°E)

The quake struck near Nishinoshima volcano, which resumed eruption on Tuesday. Intermittent eruptions have helped the volcanic island to grow by more than 12-folds in the past two years.

Located about 1,000 kilometers south of Tokyo, Nishinoshima Island currently measures about 2,000 meters across.

In 2013, an undersea eruption formed a new island near Nishinoshima, and continuing lava flows eventually linked the two islands several months ago.

Volcano Erupts in Ogasawara Islands

Warning issued to Pacific shipping after volcano erupts, forming a new Island

Authorities have warned shipping in the Pacific Ocean to maintain vigilance for airborne volcanic material after a volcano erupted near one of the Ogasawara Islands, some 1,000 kilometers south of Tokyo, NHK reported Japan’s Meteorological Agency (JMA) as saying.

Japan Coast Guard has confirmed black smoke spewing out of a new land mass about 500 meters southeast of Nishinoshima island, JMA said

Video footage shows a plume of black and white smoke and steam  rising to a height of more than 600 meters above a new landmass measuring about 200 meters across.

“The agency says multiple clusters of white smoke overhead suggest intermittent explosions,” said the report.

Volcanic activity created a new island which was fused to the uninhabited Nishinoshima between 1973 and 1974, the last time when eruptions occurred near the island.

In 2010, one of the volcanoes in the region erupted, spewing smoke and ash to a height of about about 100 meters above the sea level. The surrounding sea area changed to a greenish-yellow color with nearby areas turning cloudy.

JMA said the volcano, called Fukutokuokanoba, had erupted seven times since 1904, forming ephemeral islands (temporary land masses) on three occasions, all of which later sank below the ocean surface.

The first known ephemeral island called Shin-Iwo-jima (New Sulfur Island) was formed in 1904, and the most recent in 1986.

Tsunami Warning/Advisory

The 7.4Mw quake struck at a depth of 10km and created a tsunami which reached a height of about  3m (10 feet) in at least a dozen locations around Japan’s coastal areas

JMA said on its Website:

Tsunami Observations
As of 05:40 JST (UTC+ 9 hours)
At some parts of the coasts, tsunamis may be higher than those observed at the observation sites.
The tsunamis can become higher from now on.

However, JMA later downgraded the warning to a tsunami advisory for the area.

Aftershocks

About 3 dozen strong aftershocks were reported, as of posting, the most significant of which measured 5.0Mw. Many more aftershocks may follow in the coming days and weeks.

FEWW Forecast

More powerful earthquakes, some related to this event, could strike Japan Region, much closer to the coastal areas.

On June 13, 2010, FIRE-EARTH forecast

Fire Earth Model shows that Japan region could be struck by up to 4 additional strong to large earthquakes possibly this year/early next year, one of which could be a catastrophic event.

M6.2 Quake Strikes Izu Islands, Japan Region

More Shocks Could Strike Japan Region

Strong Earthquake Measuring up to 6.2Mw Strikes Izu Islands, Japan Region

The quake, centered at 29.8N, 141.6E,  struck Torishima Kinkai region at a depth of about 50km on Monday, 03 May 2010 19:28 JST (10:28UTC), Japan’s Meteorological Agency (JMA) reported.

Tsunami Status

JMA did NOT issue any tsunami warnings, advisory or watch, probably due to the fact that the shock occurred deep below the ocean surface.

Approximate Distances (USGS/EHP)

• 300 km (190 miles) NNW of Chichi-shima, Bonin Islands, Japan
• 405 km (250 miles) SSE of Hachijo-jima, Izu Islands, Japan
• 535 km (335 miles) N of Iwo Jima, Volcano Islands, Japan
• 685 km (425 miles) S of TOKYO, Japan

Fire-Earth Forecasts:

1. More shocks, possibly stronger than this quake, could strike Japan Region as a result of a new wave of seismic activity in the region.

2. Intense volcanic activity may occur in Japan Region in 2010.

Submarine Volcano Erupts Near Japan

Fukutokuokanoba submarine volcano erupts

White smoke was observed rising from the sea about five kilometers north-northeast of the Minami-Iwoto island in Ogasawara Islands, a Japanese coast guard patrol vessel reported, Yomiuri Shimbun said.

Smoke believed to be emanating from an underwater volcano was previously detected in the area, about 1,200 kilometers south of central Tokyo, in July 2005.

Tokyo Institute of Technology geoscience Professor, Kenji Nogami, reportedly said: “In the 1986 eruption, a new island appeared after lava accumulated. The island was washed away by waves, but seabed upheaval reduced the water depth to 22 meters in 1999. It’s possible that this [recent] volcanic activity could form a permanent island.”

The volcano reportedly ejected  smoke and ash to a height of about about 100 meters above the sea level. The surrounding sea area was reported as changing to a greenish yellow color with other nearby areas turning cloudy.

Japan’s Meteorological Agency (JMA) said the volcano, called Fukutokuokanoba, has erupted seven times since 1904, forming ephemeral islands (temporary land masses) on three occasions, all of which later sank below the ocean surface.

The first known ephemeral island called Shin-Iwo-jima (New Sulfur Island) was formed in 1904, and the most recent in 1986.
