5.2-magnitude quake shakes Southern California, tumbling rocks onto roads and items off shelves
The quake was centered in San Diego County near the mountain town of Julian, which is known for its apple pie shops, and was felt as far north as Los Angeles
A San Diego County firefighter who answered the phone at the Julian fire station said there were no reports of damage and no calls for service after what was a “good shaking.” The county police and sheriff’s departments also said they had received no immediate reports of damage or injuries.
Picture frame fell off my wall so tragic...
Tbh, it was very nice getting a warning on our phones at the same time of hearing the rumbling in the distance (a telltale sign of a coming earthquake).
TIL in the moments preceding an earthquake, nature will rumble and send out warnings to phones
When an earthquake starts, it generates these seismic waves called primary high frequency waves or P-waves that travel super fast and secondary movement waves or S-waves that come with potential damage.
Earthquake early warning systems work by detecting those initial P-waves and quickly estimate the earthquake's location, magnitude, and intensity, sending alerts before the more destructive S-waves arrive at the surface.
It's those same P-waves, which we can hear as rumbles in the ground before the shakes start.
Yeah, I got a phone warning before the last earthquake I experienced in Washington. It's pretty cool, but I got the notification probably 15 seconds before I felt it. Maybe I could have planned better if I had longer, but it was like a 4.5 so it didn't matter. Japan has a really good advanced warning system, the notification sound is pretty eerie.
