Twenty-seven aftershocks had been reported leading up to a 1 p.m. news conference, said Kate Hutton, a seismologist at Caltech in Pasadena. One aftershock was reported as a magnitude 3.6 quake.
The earthquake occurred about seven miles underground along a small fault line, she said.
School administrators in the city checked on students enrolled in summer school programs after brief, voluntary evacuations.
Officials from the Los Angeles County sheriff’s Crescenta Valley Station responded to a call at Rosemont Middle School to help a child suffering from an anxiety attack as a result of the earthquake, sheriff’s Lt. Carrie Stewart said.
Hoover High School administrators and security guards went to every classroom to check on students after the quake hit, Associate Principal Jennifer Earl said.
Staff members made sure every student was in a classroom so no one was left behind in case an evacuation was needed, Earl said.
“We wanted every kid accounted for,” she said.
Officials at the Glendale City Center Building at 101 N. Brand Blvd. sent some workers home for the day, as employees said the upper levels of the multilevel office tower swayed.
“It was obviously a shock, and I was just hoping that it wasn’t the big one when I was up there,” said Andrey Altounian, who works in the building’s penthouse. “Everybody from my office is afraid to go back up because it was really swaying.”
Other employees jumped under their desks, following the advice of others.
“The guy told us to get down,” said Apollo Yap, who was meeting with an insurance agent at the time of the earthquake. “I haven’t had that experience since Northridge.”
