For any recent followers: Hi, we're @WaShakeOut - an account run by @WaEMD's geologic hazards and preparedness team to share information about Washington's geologic hazards (especially earthquakes, tsunamis, and volcanoes), and what YOU can do to be safe when they occur!
Time to get preppin' for the Big ShakeOut!
Have you spent time along Washington’s 3,000 miles of shoreline this summer? If so, did it get you wondering what you can do to reduce your tsunami risk? Wonder no longer, because #ShakeOut is on the way! #ShakeOut is the world’s largest annual earthquake and tsunami drill. 🌊
Don't forget - In Washington we have access to the @USGS_ShakeAlert earthquake early warning system, which can provide seconds of warning before earthquake shaking arrives at your location! Learn more about how to enable this free system on your phone at mil.wa.gov/alerts!
Via National Tsunami Warning Center...There is NO tsunami threat for the US & Canadian Pacific coasts in North America (other than the areas under the Tsunami Warning in Alaska) in regards to the 7.2 earthquake. Details are available in the statement at tsunami.gov
We are still examining what exactly this means for Washington state coastlines. We are in contact with the National Tsunami Warning Center. #wawx
From the National Tsunami Warning Center: 🔴 A TSUNAMI WARNING is posted for portions of Alaska following a M7.2 earthquake 50 miles S of Sand Point, Alaska, at 12:38pm AKDT July 16. A Tsunami Alert is for this event is posted at tsunami.gov
SO AMAZING TO WATCH! Just a friendly reminder that... VOLCANOES DON'T SMOKE! 🌋🚭 It's Volcanic Ash, a mixture of exploded bits of rock and lava that's mostly silica (SiO2 - Quartz). Learn more about volcanic ash and how to reduce it's impacts at: volcanoes.usgs.gov/volcanic_ash/
A volcano erupted in Iceland early Wednesday, marking the 12th time in four years for a volcanic system near Reykjavik that has been increasingly active. The eruption blew clouds of gray smoke into the air and emitted glowing hot yellow and orange lava, but did not pose a threat…
On July 14, quakes at Mt. Rainier continue at low levels. Seismicity suggests water/fault interaction with no magmatic activity. Plot shows earthquake depths over time. This will be the last daily status update unless activity changes. Weekly updates will be posted each Friday.
Position opening at the Pacific Northwest Seismic Network. For more information and to apply please visit bit.ly/4lHmP8M
While the current earthquake swarm at Mt. Rainier is not causing concern about an eruption, it's a great reminder that we have 5 active volcanoes in Washington state, and being prepared for them is always a good idea. Learn more: youtube.com/watch?v=PETpwF…
Happy #FieldWorkFriday! Two new seismic stations are now online: CRESC and CHUTE. @uocas students Karlee and Charlie installed the seismometers! The PNSN fosters undergrads' professional development by hiring summer field technicians at both our @uoregon and @uofwa offices.
One quick point, because I'm seeing this wrong elsewhere: NO ONE has been feeling these earthquake. No one. These earthquakes are only detected from sensors. So, if you think you felt an earthquake, look out the window because it was probably a truck driving by.
Seismicity continues beneath Mt. Rainier, WA, at lower rates than yesterday. Plots show map of located swarm quakes (orange) with all quakes since 2020 (blue), and recent quake numbers/magnitudes over time. Update: ow.ly/2hnu50Wnb8H More info at ow.ly/NfyO50Wnb8F
July 11 update on Mt. Rainier seismic swarm. Earthquake rates continue to decline; cause remains consistent with hydrothermal fluids. Status update at ow.ly/ZcUs50Wor6A This plot shows the magnitudes (top) and numbers (bottom) of earthquakes over the course of the swarm.
July 10 Rainier update. Quakes continues at low rates; cause consistent with hydrothermal fluids. Status update: ow.ly/Ja8650WnRwR Present swarm now surpasses 2009 swarm in terms of number of events, rate, and energy release (attached plot compares 2009 to present swarm).
Another Information Statement and update from USGS CVO: This earthquake swarm is still within background, activity for Mt. Rainier and indicates movement of water within the #volcano, but not magma. See below and follow @USGSVolcanoes and @PNSN1 for more details
