Japan's massive 2011 earthquake may trigger more, and larger, volcanic eruptions

Japan's massive 2011 earthquake may trigger more, and larger, volcanic eruptions over the next few decades, perhaps even that of Mount Fuji - but predicting them remains close to impossible, a volcano expert said on Friday.

The nation last month suffered its worst volcanic disaster in nearly 90 years when Mount Ontake, its second tallest active volcano at 3,067 meters (10,062 feet), suddenly erupted, raining down ash and stone on hikers crowding the summit.

The eruption killed 56 people, exceeding the deaths in the 1980 eruption of Mount St Helens in the United States. Seven victims remain missing, and recovery efforts have been suspended until the spring.

Japan may well be moving into a period of increased volcanic activity touched off by the 9.0 magnitude earthquake of March 11, 2011, said Toshitsugu Fujii, a volcanologist and professor emeritus at the University of Tokyo.

"The 2011 quake convulsed all of underground Japan quite sharply, and due to that influence Japan's volcanoes may also become much more active," Fujii told reporters.

"It has been much too quiet here over the last century, so we can reasonably expect that there will be a number of large eruptions in the near future."

Four San Francisco fault lines have built up enough seismic strain to unleash destructive earthquakes

San Francisco Bay Area earthquake faults are drawn in red.
With several faults slicing through the San Francisco Bay Area, forecasting the next deadly earthquake becomes a question of when and where, not if.

Now researchers propose that four faults have built up enough seismic strain (stored energy) to unleash destructive earthquakes, according to a study published today (Oct. 13) in the Bulletin of the Seismological Society of America.

The quartet includes the Hayward Fault, the Rodgers Creek Fault, the Green Valley Fault and the Calaveras Fault. While all are smaller pieces of California's San Andreas Fault system, which is more than 800 miles (1,300 kilometers) long, the four faults are a serious threat because they directly underlie cities.

4 Northern California faults primed for major earthquakes

Three fault segments running beneath Northern California and its roughly 15 million people are overdue for a major earthquake, including one section that lies near the dams and canals that supply much of the state's water, according to a geological study published Monday.

The three fault segments and one other in the region are loaded with enough tension to produce quakes of magnitude 6.8 or greater, according to a geological study published Monday.

They include the little-known Green Valley fault, which lies near key dams and aqueducts northeast of San Francisco. Underestimated by geologists until now, the fault running between the cities of Napa and Fairfield is primed for a magnitude-7.1 quake, according to researchers from the U.S. Geological Survey and San Francisco State University.

The water supplies of the San Francisco Bay Area, Southern California and the farm-rich Central Valley depend on the man-made water system that links to the Sacramento and San Joaquin rivers, noted James Lienkaemper, the U.S. Geological Survey geologist who was lead author of the study. The Green Valley fault is last believed to have ruptured sometime in the 1600s.

El Salvador magnitude 7.4 temblor strikes off coast

A powerful earthquake hit late Monday off the Pacific coast of El Salvador, the U.S. Geological Survey reported. The temblor was recorded about 66 miles south-southeast of the city of Usulutan with a preliminary magnitude of 7.4

An earlier report from the NWS Pacific Tsunami Warning Center said "hazardous tsunami waves" were possible along the coasts of Nicaragua, Honduras and El Salvador. That report was later amended to note that there was "no longer a tsunami threat."

The USGS also issued a "yellow alert" for possible shaking-related fatalities and economic losses. Wilfredo Salgado, mayor of the city of San Miguel in El Salvador, said on his Twitter account that a man was killed when an electricity post fell on him. He also posted images of damage in the area:

Is New England's seacoast ready for an earthquake?

Since 1975 moderate size earthquakes have occurred in New Brunswick, New Hampshire, northern New York and Quebec.
"Drop, cover and hold on."

It's a message that likely hasn't reached most New Englanders who rarely worry about the dangers of a major earthquake happening here. But the threat is real.

"Definitely the risk in this area is significantly greater than most people think," said Margaret Boettcher, an assistant professor of geophysics at the University of New Hampshire who has researched the physics of earthquakes and the mechanics of fault slip.

Seacoast emergency officials agree there is a danger and people should take it seriously. While strong earthquakes are rare here, history has shown that they can happen and could pose a significant threat to many of the region's historic buildings that were constructed long before codes were put in place to protect against seismic activity. The old brick buildings in places like Exeter and Portsmouth are at greatest risk, officials say.
