Pretty damn strong shake here in Lafayette, strong enough to wake me from sleep.

Moderate shaker felt in East Bay 3 min ago.

BRITAIN could freeze in YEARS of super-cold winters and miserable summers if the Baroabunga volcano erupts, experts have warned. Depending on the force of the explosion, minute particles thrust beyond the earth’s atmosphere can trigger DECADES of chaotic weather patterns. Tiny pieces of debris act as billions of shields reflecting the sun’s light away from earth meaning winter temperatures could plunge LOWER THAN EVER before while summer will be devoid of sunshine. The first effect could be a bitterly cold winter to arrive in weeks with thermometers plunging into minus figures and not rising long before next summer. The Icelandic...

a debate is emerging between the San Francisco Public Utilities Commission (PUC) and the Bay Area Water Supply and Conservation Agency over the potential disaster if the 89-year-old Mountain Tunnel, which supplies 2.6 million Bay Area homes and businesses with water, collapses. The PUC acknowledges that the tunnel does have a chance of "catastrophic collapse," which would require repairs costing $100 million or total replacement, costing up to $630 million. But the PUC’s 10-year-old 4.6 billion water system improvement program did not include the Mountain Tunnel in its plans. ... The risk right now is that the tunnel lining could...

Mountain Tunnel, a key part of the Hetch Hetchy water system - which supplies 2.6 million Bay Area residences and businesses - is at risk of a "catastrophic collapse" and will cost more than $100 million to repair or up to $630 million to replace, according to the San Francisco Public Utilities Commission. City officials have known for 25 years that significant work is needed on the 19-mile-long tunnel just outside Yosemite National Park in a steep, hard-to-access wilderness area. They considered making it part of the PUC's decade-old, $4.6 billion water system improvement program, which is now more than...

Two people killed and eight injured in Ecuador earthquake 5.1-magnitude tremor near capital Quito caused landslide at a quarry that left workers dead People watch dust sweep the pan-American highway after the earthquake near Quito. Photograph: Dolores Ochoa/AP Two people have been killed in an earthquake in Ecuador, with eight others wounded and rescue workers still seeking to free those trapped. The 5.1-magnitude tremor near capital Quito triggered a landslide at a quarry that killed two workers there, the national risk control agency said, adding that firemen were searching for three others. "Obviously the landslide was caused by the tremor,...

At least 367 people have been killed and some 1,300 injured by a magnitude 6.1 earthquake struck in south-west China, state news agency Xinhua says. The US Geological Survey said the quake struck about 11km (7 miles) north-west of Wenping in Yunnan province at 16:30 local time (08:30 GMT).

Once overlooked because of its relative inactivity compared to other subduction zones around the world, the Cascadia Subduction Zone (CSZ) — and the potentially devastating megathrust earthquakes and tsunamis it could unleash — are today well known to both geoscientists and the public. Beginning with the efforts of John Adams of the Geological Survey of Canada and Brian Atwater of the U.S. Geological Survey in the late 1980s, a series of oceanic research cruises and datasets has steadily advanced our understanding of Cascadia. It seems like there is “a paradigm change every few years,” says Chris Goldfinger, a geologist at...

GUATEMALA CITY (AP) — A magnitude-6.9 earthquake on the Pacific Coast jolted a wide area of southern Mexico and Central America Monday, killing at least three people while damaging homes, hospitals and churches. The U.S. Geological Survey said the quake hit at 6:23 a.m. (7:23 a.m. EDT; 11:23 GMT) on the Pacific Coast 1 mile (2 kilometers) north-northeast of Puerto Madero, near the Guatemala border. It initially calculated the magnitude at 7.1 but later lowered the figure to 6.9. The quake was felt across a broad swath of southern Mexico and as far away as Mexico City, but officials...

We felt it here in the high desert, north of BBL.

...the study provides the strongest evidence yet that the upsurge quakes in the past decade across Central and mid-America is at least partially to be blamed on humans. More than 300 earthquakes have occurred from 2010 to 2012 compared to an average rate of 21 every year from 1967 to 2000, according to the U.S. Geological Survey. Most have ranged from 2.0 to 3.6 on the Richter scale but there have been exceptions, including a 5.6 event in central Oklahoma in November 2011 that destroyed 14 homes and injured two people.

Really strange place for an earthquake. Magnitude is consistent with an underground nuclear test. More at USGS site.

A tsunami warning in effect for the coastal areas of Alaska after a 7.9 magnitude earthquake was downgraded to an advisory and then canceled altogether Monday afternoon. Tsunami waves in the Alaskan cities of Unalaska and Saint Paul were expected to be less than a foot tall, the the National Weather Service advisory said. Small waves have already reached other locations in Alaska and none were higher than 0.6 feet, it said. 8.0 Alaska earthquake in Alaska poses no threat for Pacific Coast Soon after the warning was issued, people headed for higher ground in Adak, Alaska, because water was...

WASHINGTON (Reuters) - A local tsunami warning was issued after an 8.0 magnitude earthquake struck in the Pacific Ocean west of Alaska's Aleutian Islands on Monday, the U.S. Geological Survey and the National Tsunami Warning Center said. The warning covered coastal areas of Alaska from Nikolski to Attu, the center said, adding the level of tsunami danger was being evaluated for other U.S. and Canadian Pacific coasts....
