Two back-to-back earthquakes rattled the San Francisco Bay area awake around 5:30 a.m. Monday morning, the Associated Press reports. There are no reports of serious damage or injury.

While most San Franciscans were startled from sleep when the quake hit, local reporter Kristen Sze was on-air when the KGO TV studio began to shake. Watch as Sze coolly switches from a report on rallies for higher education funding to a report on the quake:

While Sze never lost her composure, she tweeted later: “I sounded calmer than I felt!”

Another KGO reporter, Mike Nicco, gave his own summary of the quake in 139 characters:

#USGS categorizes #Bayarea #earthquake light: Felt outdoors. Sleepers wakened. Liquids disturbed, some spilled. Doors swing. Pictures move.
