As people across Southern California sheltered from Hurricane Hilary; another natural disaster hit - a magnitude 5.1 earthquake, reports BBC.
Its epicentre was north-west of Los Angeles and #hurriquake was soon trending on social media.
The quake did not cause major damage, and the hurricane has also since been downgraded to a post-tropical cyclone.
Los Angeles Mayor Karen Bass said over 100 fire stations were checking buildings for damage.
Karen Bass said in a tweet that there were no initial reports of structural damage caused by the earthquake or any injuries.
Seismologist Dr Lucy Jones told NBC news it was "interesting" to have the earthquake near Ojai, and was the "first time we've had a five since 1932 in exactly this location, and even within the Ventura basin".
She warned more aftershocks were likely over the next few days.
The earthquake hit at the same time as post-tropical cyclone Hilary, which left many residents unsure where they should seek cover.
