[Editor’s Note: Monday afternoon, a power outage and subsequent explosion rocked the UC Berkeley campus and sent one student to the hospital. Scroll down to view Berkeleyside’s live blog of updates throughout the night. See a chronological version of events here.]

Update, 11:59 p.m. During UC Berkeley’s evacuation Monday due to a power outage and the explosion that followed, members of Cal’s amateur radio club remained nearby to help spread the word about the developing situation to emergency workers and ham radio operators throughout the area.

Jack Burris (amateur radio call-sign “K6JEB”) works as an IT manager for UC Berkeley’s social sciences Data Lab and is president of the radio club. He said he and another club member, Joel Martin (call-sign “KQ1N”), had attended the 9 p.m. university press conference and broadcast it on their radios to other ham operators, who had fanned out to area fire departments after receiving an informal alert about the emergency.

Burris said he had been inside Barrows Hall when the power went out around 4:40 p.m.

“Almost right away we heard that there were people trapped in the Barrows Hall elevator.… A total of about 20 people were held in there and they’ve all been let out,” he said at about 9:30 p.m.

Burris didn’t hear the large explosion outside California Hall — caused by a fire inside a steam tunnel — but he did hear a “big ‘pop'” as “everything electric immediately stopped” inside Barrows. “And at that instant, I looked out the window over at the emergency generator, which went on right away. I knew something was up with the electrical in the building but there were no alarms, which was strange.”

He said the IT staff decided to evacuate immediately regardless.

“As we were going down the stairs, pretty much everyone else in the building was doing the same thing,” he said. As it was the end of the day, with work winding down already, he said the mood was calm. “It was very orderly. There was no panic. Nobody was running. We do have drills, and most of us thought originally it was just another one of those.”

Added Burris shortly before 10 p.m. as he surveyed the still-dark university grounds: “I’ve never seen anything like this. They’ve never emptied campus like this in the whole time I’ve been here.”

As of 11:15 p.m., partial power to the campus had been restored. According to university officials, efforts to get the rest of the campus power system online will continue overnight. A decision about whether or not classes will be in session is expected by 5 a.m. Tuesday.

Listen to an extended interview with Burris via CalTV here.)

Update, 11:05 p.m. According to the ASUC president, Cal administrators will make the final decision on whether or not to hold classes Tuesday at around 5 a.m.

Update, 9:39 p.m. Cal spokesman Dan Mogulof held a press conference at 9 p.m. to update the media about Monday’s power outage and subsequent explosion, which sent one student to the hospital with minor injuries. Berkeleyside’s Frances Dinkelspiel was on scene for the event.

“According to witnesses, the explosion was about two stories high and as wide as a two-lane street,” he said.

Mogulof said the power outage, at 4:30 p.m., was related to vandalism that had taken place previously within a mile of campus. He told Berkeleyside earlier Monday that the vandalism had been going on for quite some time. The campus experienced some electrical problems over the weekend, which led authorities to realize there was a problem. He said officials thought the problem was fixed, but then the power went out Monday. Cal turned on its emergency generators, which led to an explosion that blew a cover off a manhole near California Hall at 6:30 p.m.]

Mogulof said that all dorms are currently without power. Said Dinkelspiel, almost everywhere on campus is black except for the Campanile and Sproul Hall: “Nobody can remember a time when the campus has been evacuated like this.”

Mogulof said Cal has 14 power stations around campus, where electrical engineers are on-hand with Berkeley Fire Department personnel who will be working to bring the power back online gradually. There is some concern that there could be another explosion, he said.

Mogulof said some people were trapped in an elevator from about 6:30-8:30 p.m., but that they were rescued by Berkeley Police and Fire personnel. He also confirmed that there was a small ammonia leak but said it had been contained quickly.

Mogulof said the university is hoping to hold classes tomorrow, and that there will be another briefing at 10 p.m.

Mogulof said the university has been fielding calls from many “worried parents,” and assured those who had gathered: “There are 50,000 people who work, teach and study here, so we’re not going to do anything to put people in harm’s way.”

Update, 9:15 p.m. Cal has confirmed that there was a small ammonia leak on campus earlier today. According to an unconfirmed notification, the leak was reported at 5:39 p.m. at Latimer Hall, which is south of Gayley Road across from the Hearst Greek Theatre.

Update, 8:59 p.m. UC Berkeley is asking everyone to “stay away from central campus until further notice,” according to an update posted at 8:45 p.m. “Campus officials are monitoring the situation.”

No information has been posted yet about the status of classes Oct. 1.

Update, 8:45 p.m. Berkeleyside editor Frances Dinkelspiel reported from the scene that, despite class cancellations, some students were still trying to get a night’s work in. She said a group of about 14 students had set up an impromptu classroom on Center Street near Shattuck Avenue right on the curb outside the Bank of America building. The biology students were heading to a review session when they were told to leave campus.

“We went to the classroom where the review was supposed to happen, but we were told to evacuate,” said second-year student Diego Dubom. “And then we started moving our way from campus down to where we are now.”

UC Berkeley has confirmed via Twitter at 8:41 p.m. that everyone who had been stuck in elevators has been rescued. For more updates, call 800-705-9998.

Update, 8:28 p.m. UC Berkeley authorities report via Twitter that one student with minor injuries was transported to the hospital following Monday’s explosion. Two or three people with minor injuries declined to be taken to the hospital; authorities were unsure whether or not these individuals were affiliated with Cal.

Via Twitter: “As far as we know, all those stuck in elevators were rescued. Don’t know if classes are on for tomorrow yet.”

Update, 8:21 p.m. As of 8:12 p.m., Cal reports that “Email has been restored and other systems are coming online.” Berkeleyside readers are reporting multiple power outages in different buildings throughout the day — in Morrison Hall, Dwinelle Hall, Wurster Hall and the Energy Biosciences Building — prior to a more widespread outage at 4:30 p.m.

Wrote one Cal employee about the scene at Dwinelle: “We’ve never had a power outage since I started working there; it was surreal, and there were loud motor noises coming from outside.”

Update, 7:52 p.m. Cal spokesman Dan Mogulof said the campus is closed but the fire appears to be out. Berkeley Police and Fire are on the scene.

Mogulof said the the cause of the explosion, which followed a widespread power outage at 4:30 p.m., “appears to be related to an incident of vandalism on our electrical system.” He said vandals had been digging up copper grounding wires on campus, “which caused extensive damage to the electrical system.”

The vandalism was discovered late last week, but “it appears it had been going on for quite a while.”

Mogulof said the visible damage had been repaired on the weekend.

“What happened today is an indication that the vandals caused far more damage than we could originally see or assess,” he said just before 8 p.m. Monday.

Mogulof said the explosion, outside California Hall at about 6:30 p.m., sent one person to the hospital, but the injuries were minor. He said no information was available about the identity of the person who was injured, such as whether it was a student.
