In the wake of the Fukushima nuclear disaster, it's imperative for California to have more definitive knowledge about the seismic hazards near the Diablo Canyon Power Plant. An additional fault in the area was only recently discovered, and more seismological information is needed about existing faults. Technology has improved tremendously since the nuclear plant began operating in 1985, and license renewal for its two reactors - a process that takes years - shouldn't go forward without this information.

Pacific Gas & Electric Co. was scrambling Monday to salvage plans to conduct seismic surveys using sonic blasts off the coast near the Diablo Canyon nuclear power plant after a state regulatory agency staff report concluded it would disturb more than 7,000 marine mammals. The California Coastal Commission staff, in a report released Friday, recommended that the commission deny PG&E's application for a coastal development permit needed to begin the project. The staff cited "significant and unavoidable impacts to marine resources," including threatened and endangered whales, porpoises and sea otters.

A long-awaited study released Wednesday says the controversial oil extraction method known as hydraulic fracturing, or fracking, would not harm the environment if used at the Inglewood Oil Field in the Baldwin Hills area. The yearlong study included several issues raised by residents living around the field, such as the potential risks for groundwater contamination, air pollution and increased seismic activity. For months, water wells on the 1,200-acre field were monitored. Data from ground and air monitors were collected and analyzed, but no effects were recorded before or after the technique was used, the study says.

An "earthquake storm" continued to rattle Imperial County late Sunday, with the region experiencing hundreds of mostly low-intensity temblors that could be felt in neighboring counties. The seismic activity is not unusual for the area around Brawley, a city of about 25,000 where the quakes were centered and located between the San Andreas and Imperial faults, experts said. The spurt of smaller quakes does not necessarily herald that the Big One is on its way, they said. After a series of milder quakes in the morning, a magnitude 3.8 temblor hit at 10:02 a.m. about three miles northwest of Brawley, and was followed by a nearly continuous series of quakes in the same general area, according to the U.S. Geological Survey.

Southern California Edison announced Friday that it will collaborate with the Scripps Institution of Oceanography on seismic studies looking at offshore faults near the San Onofre nuclear plant, beginning later this year. Edison requested approval last year from the California Public Utilities Commission to recover $64 million from ratepayers for seismic studies that will help to determine the future of the plant. Caroline McAndrews, Edison's director of nuclear strategic projects, said the collaboration with Scripps will account for about half of that.

A team of engineering and seismic experts announced Wednesday that a controversial proposal to build the Westside subway extension under Beverly Hills High School is safer than a fault-ridden route beneath Santa Monica Boulevard. The panel, assembled by the Los Angeles County Metropolitan Transportation Authority to analyze two possible alignments through Century City, also concluded that tunneling can be done under the campus and nearby homes without endangering or disrupting the community.

The 7.2 earthquake that rattled the U.S.-Mexico border in 2010 — the largest temblor to hit Southern California in nearly two decades — has exposed a hidden weakness in school seismic safety that officials are now trying to correct. The Easter Sunday temblor was centered south of Mexicali but was felt strongly in several Imperial County communities. Schools withstood the shaking structurally, but the damage was still extensive. Walkway coverings cracked and collapsed; light fixtures crashed to the floor; electrical wires were exposed; water and gas lines ruptured; and classroom ceilings and roofs were damaged.

Authorities were still looking for answers on Friday, one day after a 10-ton tree toppled onto a car waiting at a stoplight, crushing the driver. Haeyoon Miller, 29, was killed when the trunk of the 50-foot eucalyptus tree slammed into the roof of her Hyundai Accent as she waited at 17th Street and Irvine Avenue on Thursday afternoon. The Orange County coroner's officer listed the cause of death as accidental blunt-force trauma. Public safety officials and seismic and horticultural experts were investigating the accident but had only theories to work with, from moist soil to trimmed roots to this week's magnitude 3.5 earthquake in Newport Beach.

A magnitude 4.2 earthquake fluttered through much of Southern California on Thursday afternoon, the largest quake to be felt in the Los Angeles area in more than a year. But the shaking was so soft many people just carried on with their day. "Just a rolly," said an operator at Olive View-UCLA Medical Center in Sylmar, two miles southeast of the epicenter in the San Gabriel Mountains. "It didn't even move my chair. " "There was no screaming out that I was aware of," said Joe Keys, a hospital assistant administrator, who described the quake as lasting only a few seconds.

A college football fan recently rescued after two years on a deserted island — please play along here — was asked to make this year's conference picks. He liked Nebraska in the Big 12, Boise State to win the Western Athletic and Brigham Young and Utah to battle it out in the Mountain West. Told those schools were no longer in those leagues, he quipped, "Whoa, next you'll tell me Texas joined the Pac-10. " No, but almost. College football avoided (for now) the "Big Bang" cosmic conference shift, yet the Big Ten alone underwent so much realignment it could have split into the "Sciatica" and "Lower Lumbar" divisions.
