Something spooky is afoot near Lake Isabella! This week, our field team is investigating a mysterious outage at one of our seismic stations. The backup power checked out, but a lost connection may be to blame. The case is still open! #ShakeAlert #CalOES

EQ History: Oct 21, 1868: A M6.8 quake on the Hayward Fault, called the “Great San Francisco Earthquake” until 1906, inspired the first known earthquake early warning idea: sensors wired to an alarm bell in a city tower. Today we call it #ShakeAlert! ⚡#EQHistory By Unknown author - buff.ly/bX2t8EJ

Apparently this alert doesn’t go away unless you explicitly action it. I wonder how long I can go without doing that.

Reminder this is today: At 10:15am, BART staff will trigger our ShakeAlert early warning earthquake system to ensure it is functioning and working correctly. Once triggered, trains will automatically slow down to 27mph. Then all trains will come to a very brief stop.

Practice makes perfect! The students at Fremont High school have been well trained with regular drills to help them remain safe at school, and they can take those lessons home to their family! Great job everyone, and thank you having such an important event! #ShakeOut #CalOES #ShakeAlert #prepare

At precisely 10:16 am PDT, ShakeAlert sent my annual notification to Drop, Cover, and Hold On.
It was an earthquake simulation drill to remind us what to do "If or when".
Practice establishes an automatic response. Invaluable in emergencies ❣️Lynn

Washington joins the Great ShakeOut at 10:15 a.m. Thursday 🌎 Practice: Drop, Cover, Hold On. With a 10–15% chance of a magnitude 9 Cascadia quake in 50 years, preparedness matters. 📱 Sign up for ShakeAlert. https://hyperlocalnews.website/seaen/washington-prepares-for-earthquakes-with-great.html

BART is an early adopter of the ShakeAlert system, which is connected to a network of USGS seismic sensors throughout California. When the BART seismic condition threshold is reached is reached, the system sends a speed restriction command to trains.

How Calabasas residents get evacuation notices: Genesys Protect, county alerts and apps
LA County and city presenters explained evacuation zones mapped on a Genesys Protect platform, county opt‑in alerts and recommended apps (WatchDuty, PulsePoint, ShakeAlert), and advised NOAA SAME programming or county opt‑in to limit extraneous alerts.

#FieldPhotoFriday A little backup goes a long way! Connection issues kept our station near Cajon Pass from reliably supporting #ShakeAlert. Our field crew added satellite alongside cellular telemetry, keeping data flowing for quake detection and early warning. #CalOES

Are there advancements in earthquake prediction or early warning detection beyond what already exists (i. e. ShakeAlert in the US) that you know of?
