"It's still kind of happening like my apartment, shakes from the aftershock. Every 20 minutes or so," Prozzie said.
He said people in his area were going about their day normally afterward.
"Seeing how the locals react to it made me feel a lot more comfortable. A lot of people sort of walked out of their buildings and checked on their neighbors and that kind of made me feel a lot more calm. But definitely as it was happening, I was like oh man," Prozzie said.
At San Francisco International Airport, ABC7 News spoke with passengers who were in the air as the quake struck.

"They're all fine, just have to clean up. The whole household got messy. Yeah, it's really scary," Lee and Tsou said.
They said earthquakes are common so most people are prepared.
"It's in the zone, but most people get used to the smaller ones. The bigger ones of course is scary," Tsou said.
Fremont, California resident Hsioping Pseng said his parents felt the quake 150 miles from the epicenter. He's relieved to hear his loved ones are OK.
"So we have some broken bottles here and there but good thing no one got hurt. What I heard from the messenger app, it looks like most of my friends they are OK," Pseng said.
