Tomorrow (10/17) marks 35 years since the devastating Loma Prieta earthquake occurred on the San Andreas fault in northern California. This earthquake resulted in 63 deaths and $6 billion dollars in property damage. #LomaPrieta #earthquake California Department of Conservation

(2) The damage from this earthquake, especially in and around Oakland and other parts of the San Francisco Bay area, led California to pass the Seismic Hazards Mapping Act.

(5) Mapping seismically hazardous zones is just one way that the #CaliforniaGeologicalSurvey works to make California seismically safer. #CGS Learn more on our website:

(4) "Zones of required investigation” help identify where higher building standards may be necessary for safe development. Read more about them in our blog here:

(6) That’s also why we participate in @GreatShakeout, the world’s largest earthquake drill. This exercise helps people to plan and practice their earthquake drills, which can help decrease earthquake risk and improve community resilience.

(3) The #SeismicHazardsMappingAct directs the #CaliforniaGeologicalSurvey to map areas that may be susceptible to liquefaction, earthquake induced landslides, and other types of ground failure that can occur as the result of earthquake shaking.

@CalConservation Did Santa Cruz benefit from the mountain range absorbing some of the impact considering the relatively short distance from the slip strike?

Awesome thread!

@CalConservation What's the Risk? What you need to know about Children and Earthquakes: #PrepTheKids #ShakeOut #Earthquakes

@CalConservation And now we have #eews technology from @USGS_ShakeAlert to help mitigate damage, injury and death. The more folks that use the technology, the better.

@CalConservation $6 billion or 6 billion dollars Not both. Not together. Your third-grade teachers would be appalled.
