What will happen to our buildings during the next quake?
NSF's I-Corps Program is helping us figure out how to connect our data with the people who care. Here is what we learned...

Out now: BSL Director, Prof. Richard Allen, talks about the importance of research to public earthquake safety & explains how the Lab pushes research findings into action via @MyShakeApp and @USGS_ShakeAlert in partnership w/ @Cal_OES. View our story now at https://t.co/RKk1HqbnKC

More small quakes in San Ramon. We discussed the the ongoing swarm on KQED's Forum earlier this week. https://t.co/BFIWe4R1Co

Great to see the Android Earthquake Alerts system on the top 10 breakthroughs list for 2025! https://t.co/R5zp1YcH2Z

@UCBerkeley crew works through blustery storms to retrofit a unique seismic station in the @BerkeleySeismo network - earthquake sensors on the Farallon Islands (w/ video) https://t.co/kZz9sfAjqY

Warning time for MyShake users was up to 10 seconds for the Malibu #earthquake today. Download the free @MyShakeApp

[MyShake @MyShakeApp]

A M4.6 earthquake occurred today at 1:47pm Pacific time near Malibu, CA. MyShake successfully distributed an alert to our users. Remember to drop, cover, and hold on when you receive an alert or feel shaking.

[Richard Allen @RAllenBerkeley]

@OfHella @MyShakeApp @BerkeleySeismo @Cal_OES Did you know half the injuries in earthquakes are due to things falling on people or people falling over? Using the alert to Drop, Cover, and Hold on could halve the number of injuries in a quake. So, yelling "DUCK" and having people respond can really help!

[Richard Allen @RAllenBerkeley]

Feel today's M5.5 quake? Did you get a warning? People with the @MyShakeApp got up to 15 sec warning. Want a warning for the next earthquake? Download the free app! @BerkeleySeismo @Cal_OES #earthquake

The MyShake Alert App: California's early warning earthquake alert system app. Hear all about it on the https://t.co/J1HMnifMgg podcast from @JimSanFrancisco

#EarthquakeEarlyWarning is expanding around the globe thanks to @Android smartphones and regional networks. Imagine what else might be possible when the private and public sector partner: scientific discovery and hazard reduction.

Today we used @MyShakeApp to investigate how to interpret seismographs! And apparently a selfie I the teacher’s to celebrate of course 🙃 #geology #earthquakes

[Richard Allen @RAllenBerkeley]

Israel gets new earthquake warning system. They use the same EPIC algorithm developed @BerkeleySeismo for #ShakeAlert. Congrats to all those involved! https://t.co/lapDYCfTDy via @timesofisrael

[Richard Allen @RAllenBerkeley]

Now we are able to issue earthquake alerts, the challenge remains to help people respond and protect themselves. Great review from @DareBaldwin. Don't forget to download @MyShakeApp! https://t.co/AUAyIf8yDD via @ConversationUS

[Survivor  @Damage_Piece]

This alert came 15sec before earthquake #EqNZ #Wellington

[Richard Allen @RAllenBerkeley]

@BerkeleySeismo is now connected to the state microwave network. Thank you @Cal_OES for making this connection so that @USGS_ShakeAlert is even more robust. Be #QuakeReady by downloading @MyShakeApp

[Richard Allen @RAllenBerkeley]

Congrats to those who participated in the #earthquake #ShakeOut yesterday and received the @MyShakeApp test alert. This is why we have early warning alerts: 30 sec to get ready for shaking in #eqnz yesterday

[Richard Allen @RAllenBerkeley]

Just got the @MyShakeApp test #earthquake alert for #ShakeOut. I have the free @MyShakeApp on my phone, and it sends the alert to my watch. MyShake sent the alert to 727,956 phones across CA and OR! Ready for the next quake...
