USGS ShakeAlert

What can @USGS ☘️ Green☘️ do for you today? No luck needed to get earthquake early warning alerts from #ShakeAlert! ☘️Check out this pot of gold 🌈 usgs.gov/FAQ/BeShakeAle… @USGS_Quakes @UOHazardsLab @PNSN1 @CaltechSeismo @OregonOEM @Cal_OES @FEMARegion9 @FEMARegion10 @CAGeoSurvey

Ever wonder how we monitor 300+ stations to keep Oregon safe? 🌲 Our Director, Leland O’Driscoll, joins the "This is Oregon" podcast to talk #ShakeAlert, AI fire detection, and building a more resilient state. 🔊Listen: linktr.ee/ohaz_uo #GoDucks #STEM #Oregon

Today give that special 💝 by getting someone to Be ShakeAlert Safe! The 🎁 of safety keeps on giving. Learn more: usgs.gov/FAQ/BeShakeAle… Happy Valentine’s Day! @Cal_OES @UOHazardsLab @CAGeoSurvey @OregonOEM @waShakeOut @PNSN1 @USGS_Quakes @USGS @ListosCA

At #ShakeAlert we’re all about💕. How much data do we need to estimate a quake’s location, magnitude, & how hard it’s going to shake? Put your hand on your heart - the data collected in the time of a couple of heartbeats is enough. 💚💚

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: buff.ly/pmBe63b

@USGS_Quakes @ImperialCntyCA @Cal_OES @FEMARegion9 @CAGeoSurvey @ListoSanDiego @ListosCA #ShakeAlert estimated that MMI 3 (weak) shaking reached CA causing alert delivery to phones. See how the MMI 3 (shown as MMI 2.5) polygon crossed the US/Mexico border? More: earthquake.usgs.gov/earthquakes/ev…

@USGS_Quakes @ImperialCntyCA @Cal_OES Question: If the #ShakeAlert System operates in CA,OR, & WA why could alerts be delivered to phones in CA by an earthquake in Mexico? @Cal_OES @FEMARegion9 @CAGeoSurvey @ListoSanDiego @ListosCA

Good morning Southern California! Did you feel the M4.2 quake about 5 miles northwest of Delta, Mexico at 12:38 am? The #ShakeAlert system was activated. See: earthquake.usgs.gov/earthquakes/ev… @CAGeoSurvey @Cal_OES @ListosCA

Nevada is one step closer to having @USGS_ShakeAlert earthquake early warning

@MyShakeApp Everyone in CA, OR, & WA can Be #ShakeAlert Ready! It’s an important tool in your quake safety toolbox. Power your phone with ShakeAlert today: usgs.gov/FAQ/BeShakeAle… @ListosCA @FEMARegion9 @CCCounty

Since the #ShakeAlert system estimated this quake below magnitude 4.5, alerts were *not* delivered to cell phones or other devices by our partners @MyShakeApp and cell phone operating systems.

Good morning Northern California! Did you feel the magnitude 4.3 earthquake about 2.5 miles southeast of San Ramon at 7:01 am PT. The #ShakeAlert system was activated. See: earthquake.usgs.gov/earthquakes/ev… @Cal_OES @CalConservation

Happy #FieldWorkFriday 🛠️ This week, our field techs serviced seismic site VERN—swapping batteries, adding a solar panel, and completing routine maintenance to keep stations running 24/7 for real-time data and @usgs_Shakealert

We know that feeling the ground shake can be unsettling. Are you #ShakeAlert Ready? Learn how to receive #EEW alerts on your phone: usgs.gov/FAQ/BeShakeAle… @RiversideOEM @Cal_OES Stay safe!

The #ShakeAlert system estimated this quake at/above magnitude 4.5 and alerts were delivered to cell phones. Did you receive an alert? Share a screenshot if you want. Thank you!

Good morning Southern California! Did you feel the magnitude 4.2 quake about 12 miles northeast of Indio at 12:30 am? The #ShakeAlert system was activated. See: earthquake.usgs.gov/earthquakes/ev… @CAGeoSurvey @Cal_OES @USGS_Quakes

@USGS_Quakes How much data does #ShakeAlert need to estimate a quake’s location, magnitude, & how hard it’s going to shake? Put your hand on your heart - the data collected in the time of a couple of heartbeats is enough.

Why did the #ShakeAlert system estimate this quake at M4.5? Our earthquake detection software aims to be fast and accurate with only a tiny amount of information available in the first seconds after a quake begins. Our goal is to maximize safety. @USGS_Quakes

Good morning Southern California. Did you feel the magnitude 3.7 quake about 12 miles north of Indio at 12:20 am? The #ShakeAlert system was activated. See: earthquake.usgs.gov/earthquakes/ev… @Cal_OES @CAGeoSurvey
