(WAFF) - Two dogs enjoying a cat nap got a rude awakening in San Francisco when an earthquake hit.
Gus and Gizmo were snoozing peacefully until moments before the shaking started.
The rattle rattled their nerves, sending them into full alert mode.
The epicenter of the 4.0 magnitude quake is just north of San Francisco.
Seven aftershocks followed. There are no reports of injuries.
