Statewide California Earthquake Center

This excellent new animation from @UNDRR shows earthquake safety actions and also includes guidance for people who use mobility devices; learn what to do in other settings at EarthquakeCountry.org/step5 and ShakeOut.org/dropcoverholdon

"Earthquakes are one of nature's deadliest hazards. In seconds, they can turn homes into ruins, undo decades of progress & claim thousands of lives." - Guterres Most earthquake deaths result from collapsing buildings ➡️ ow.ly/W1ZM50YR6Jj #EarthquakeDay #BuildingResilience

As the global home for Great @ShakeOut Earthquake Drill coordination, @SCEC encourages support and awareness of this important new annual day to Remember, Protect, and Build Disaster Resilience.

📢 Smart public policies can prevent earthquake disasters. Most earthquake deaths result from damage to buildings & infrastructure – we can protect people from this. 🕯️ Remember. Protect. Build disaster resilience. ➡️ ow.ly/Ie8o50YQwTC #BuildingResilience #EarthquakeDay

California had damage from this tsunami, especially along the north coast. Everyone can take actions to be prepared (& practice what to do if along the shore) by participating in California's Tsunami Preparedness Week (March 21-29)- visit tsunamizone.org/california to learn more.

Today marks the 32nd anniversary of the 1994 Northridge earthquake. The M6.7 quake beneath the San Fernando Valley became the costliest U.S. natural disaster until Hurricane Katrina (2005). Learn more: EarthquakeCountry.org/northridge/fac…

SCEC bridges the gap between cutting-edge science and preparedness for a more resilient California, through education, research, and more realistic earthquake simulations. Learn more at: SCEC.org/prepare.

SCEC engages stakeholders across geoscience and related fields through workshops, drills, and collaborations to advance earthquake science, education, and preparedness. Find out more at: SCEC.org/community.

The SCEC community comes together to amass data that can facilitate the research of the San Andreas Fault System. View our Community Earth Models and learn more at SCEC.org/earthquake-sys….

From physics-based simulations to community earth models, SCEC’s research computing program uses advanced cyberinfrastructure to better understand earthquakes and their impacts. Explore current priorities at SCEC.org/research-compu….

Do you know where your local #earthquake hazards are? The first step to #preparedness is knowing what to prepare for! Visit SCEC.org/prepare to learn about the geohazards near you.

The 2025 Great @ShakeOut press conference at the @LACity Emergency Operations Center featured remarks from Los Angeles Mayor @KarenBass and leaders of @ECA, @LAFD, @ReadyLA, @Cal_OES, @SCEC, @RedCrossLA, and @ENLA_VOAD.

SCEC scientists at @USC, @Caltech, and @UofIllinois warn that “supershear” #earthquakes (which can cause more intense shaking) may be more common than previously understood. Learn more at latimes.com/california/sto… and watch an overview from @USCdornsife at youtu.be/9SLAzT4vHn4.
