A 3.9-magnitude earthquake in the area of Valle Vista was felt as far southwest as Temecula, according to Patch readers.
Patch in Temecula, centered in the northwest part of the city, felt nothing, in the living room of a home on Margarita Road.
But our readers said they did.
"Felt like a boom in French Valley....made my dog bark once," Aaron Hernandez wrote on Temecula Patch's Facebook page.
According to the U.S. Geological Society, the quake's epicenter was six miles southwest of Valle Vista.
It was reported at 12:47 a.m., even as there were ongoing reports of a 7.7- magnitude earthquake in British Columbia, followed by tsunami warnings for Hawaii and Northern California.
Jen Tulpule, of Temecula, also wrote on Facebook that she felt it.
"Yes in Temecula, it shook the walls of the house," she wrote.
There were no initial reports of damage or injuries and the skies remained clear, at 53 degrees, according to the Weather Channel.
