UC Berkeley acts after concrete falls at Edwards Stadium

After chunks of concrete fell from under the bleachers of Edwards Stadium causing safety concerns, UC Berkeley has closed part of the building and initiated plans to install a temporary fix for the aging facility, according to a university official. Cal employees with offices under the bleachers have been ordered to vacate by today, Thursday.

Starting Monday July 25, construction will begin on nets designed to catch any further falling concrete — the chunks being the result of years of water damage, real-estate division spokeswoman Christine Shaff told Berkeleyside.

“The netting installation should start next week, and in preparation for the installation we’re moving equipment and staff out of the tunnel,” she said.

Rated “poor” by the university’s Seismic Action Plan for Facilities (SAFER) — meaning expected to sustain “significant” damage that will have deadly consequences in case of a severe earthquake — the stadium is on the university’s list of structures to receive seismic retrofitting. But the university does not currently have the funding necessary to complete the fix.

Falling blocks of concrete and the water damage that has caused them are a distinct, unrelated problem from the potentially life-threatening susceptibility to earthquakes, Shaff said. … Continue reading »

Big Screen Berkeley: ‘Where to Invade Next’

We all know what to expect from a Michael Moore film: snark. Though politically pointed and frequently hilarious, Moore’s bad attitude has been offending viewers ever since his groundbreaking boob tube series ‘TV Nation’ aired for a single season in 1994 (who can ever forget the Serbo-Croatian peace process pizza party?).

Now comes Moore’s latest feature, Where to Invade Next (opening at Landmark’s California Theatre on Friday, Feb. 12). Has the enfant terrible of documentary filmmaking toned things down since his last polemic, 2009’s Wall Street takedown Capitalism: A Love Story — or is his passive-aggressive sarcasm still in full flower?

The first five minutes of Where to Invade Next suggest that little to nothing has changed in Moore-land. Beginning with patriotic imagery, martial drumbeats, and a fictional visit to the Joint Chiefs of Staff, the film seems intent on repeating themes previously examined in Fahrenheit 9/11. … Continue reading »

An earthquake in neighboring Oakland jolted Berkeley awake just before 6:50 a.m. Monday.

The US Geological Survey (USGS) initially registered the quake as a magnitude 4.2, but soon downgraded it to a magnitude 4.0. Its epicenter was two-thirds of a mile north of Piedmont (3.2 miles southeast of Berkeley). It struck at 6:49 a.m.

BART held trains while it undertook a system-wide check. It estimated it would be a 10-minute delay at 7:14 a.m. At 7:26 a.m. BART tweeted: “No damage found to tracks or yards following small quake. All trains held for inspection and moving again.”

At 7:13 a.m. the CHP tweeted that no damage had been reported on any Bay Area freeways. … Continue reading »

Water conservation gets serious with restrictions, fines

Hosing down your driveway, watering your yard more than twice a week, or washing your car with a hose without a shutoff nozzle are forbidden in Berkeley, as the East Bay Municipal Utility District (EBMUD) faces its worst water supply in nearly 40 years.

These are a few of the new mandatory conservation restrictions announced last week by the utility district, which is seeking a 20% water reduction for all of its 1.3 million customers, compared to 2013.

The yard watering must be before 9 a.m. or after 6 p.m. and not within 48 hours of a measurable rainfall, and sidewalks can’t be washed either. … Continue reading »

The unsolved mystery of the Berkeley boom

For more than a month, residents around Berkeley have wondered online about a recurring nighttime boom that has woken babies, freaked out pets and set off car alarms.

The sound, which has become known on Twitter as the #BerkeleyBoom, has been heard around the city, though it has been concentrated primarily in the southern part of town.

On numerous instances, police have gone out to investigate, but were unable to locate the source and found no indication of a crime. City spokesman Matthai Chakko said Monday there have been no calls to Berkeley’s 311 service center about the sound. So its source remains a mystery.

On Sunday, a Twitter user named LP described the “Loudest #Berkeleyboom yet. Scared me half to death. @berkeleyside – seriously – is this still ‘fireworks’?!”

Heather Hardison added: “I could hear all my neighbors up talking about it in startled voices. What the heck is it?”

Wrote cirus206: “I might not know what #berkeleyboom is but damn would I like to find out.” … Continue reading »

Sunday’s quake: UC Berkeley scientists gave 10-second warning; a wake-up call for emergency preparedness

Unbeknownst to some, the magnitude 6 Napa County earthquake that woke many people up in Berkeley at 3:20 a.m. on Sunday morning was “predicted” by scientists in our very city with a 10-second warning about the trembler.

The alert was issued by the UC Berkeley Seismological Laboratory’s ShakeAlert earthquake early-warning project. The demonstration warning system provided 10 seconds warning (as shown in the video above) at laboratories in Berkeley, San Francisco, Oakland and San Jose. It preceded a quake that was the largest to hit the San Francisco Bay Area since the devastating 6.9-magnitude Loma Prieta earthquake 25 years ago in 1989.

ShakeAlert is not a predictive tool — predicting quakes is still beyond the expertise of even the most eminent seismologists; rather it is being developed to act as an early-warning system to help minimize quake damage. For example, with even a little warning, BART trains could slow down to avoid derailment, utilities companies could shut off gas vales to prevent fires, elevators could be stopped and their doors opened at a floor, and surgeons could stop operating.  … Continue reading »

People took to Twitter almost immediately after the quake, which was felt around the Bay Area and lasted a significant time. It was described by one person as “a long roll.” … Continue reading »

According to the U.S. Geological Survey, a 3.2-magnitude earthquake jolted Berkeley awake at 1:07 a.m. It was followed by two smaller aftershocks in the area within 20 minutes, a third aftershock at 2:06 a.m., and another at 2:15 a.m.

Initial reports placed the epicenter of the first temblor in Tilden Regional Park near Seaview Trail and Vollmer Peak Road, with a quake depth of 4.5 miles.

Numerous Berkeley residents on Twitter said it woke them up. Said Seth Candin: “Whole building jumped and shook.” Added Robert Gordon: “Apartment definitely just shook!”

Some called it scary, and others described it as small, but many noted that they most certainly felt it. … Continue reading »
