125 years of recording #earthquakes in #Victoria, Canada! On September 3, 1898, a Milne seismograph began operation in the basement of the old Customs House building on the Victoria waterfront. It was one of the first seismographs in Canada: science.gc.ca/eic/site/063.n…… @GSC_CGC

Alaska Seismology in Schools, the brainchild of @UAFairbanks undergraduate student Gabriel Low, aims to get students interested not just in seismology but in science in general. @AKearthquake @IRIS_EPO gi.alaska.edu/news/uaf-stude…
Titled "Mount St. Helens: A Mountain Reborn," our geology team created this new poster in partnership with @USGS to honor Volcano Preparedness Month. Follow this link and zoom in to see every crevice, scar, and glacier in all its high-res glory: flickr.com/photos/wastate…
Body waves (P and S waves) from distant earthquakes travel a curving path through the earth. As a result, they arrive at distant seismic stations from below. iris.edu/hq/inclass/ani…
Showing off one of our brand new @NRCan EEW sites near Ottawa. Thanks @HallieCBC for your interest this morning! can01.safelinks.protection.outlook.com/?url=https%3A%…
What's shakin'? A new system that will give public a heads up before the earth starts to moves underfoot. @HallieCBC takes a closer look at a new earthquake early warning system that's being installed in Ottawa this week, with Claire Perry in Cumberland.

Why @ShakeOutBC? #DYK that a M7.8 #earthquake struck off southern #HaidaGwaii in 2012? It produced shaking that was felt across much of British Columbia, 1000’s of aftershocks, and the world’s largest tsunami that year. Register today: shakeoutbc.ca/register/ 21 Oct. 10:21 a.m.
@gasfarge @IPGP_officiel shows how input fluid flux controls low-frequency earthquake (LFE) occurrence and behaviour in subduction zones: agupubs.onlinelibrary.wiley.com/doi/abs/10.102…
¿Cómo está evolucionando la sismicidad en el sistema volcánico de Cumbre Vieja? Averígualo en estas figuras y explicaciones / How is seismicity evolving within the Cumbre Vieja volcanic system? Find out in these figures and explanations #LaPalma #ErupcionLaPalma #LaPalmaEruption
#LaPalma #Eruption High-precision, relocated seismicity under Cumbre Vieja from Jan 2021 to today. Orange pyramid is location of surface eruption vents. @IGNSpain #ErupciónLaPalma

👏 to S. Antoine for her 1st paper now in-press in BSSA! High-res. optical correlation for #Ridgecrest #earthquake reveals diffuse deformation and detailed rupture patterns. Preprint here: ipgp.fr/~klinger/web_Y…
Good morning! #ShakeAlert is actively investigating system response to yesterday's quakes in the eastern Sierra. There are fewer seismic stations in this area and which made it more challenging for ShakeAlert to rapidly estimate the quake's magnitude and shaking. @Cal_OES
Séisme de magnitude 3.9 près de Épiphanie, Québec. Secousses ressenties plus de 200 km (à Ottawa et à la ville de Québec). C’est le séisme le plus fort à frapper la région depuis le 10 octobre, 2012: earthquakescanada.nrcan.gc.ca/recent/eq/inde… L’avez-vous ressenti? Laissez-nous le savoir!
Today's M3.8 earthquake 45 km NNE of Montréal has been felt across southern #Québec and eastern #Ontario, to distances of more than 200 km (Ottawa and Québec City) This is the largest earthquake here since a M4.5 on Oct. 10, 2012. Earthquakes in SE Canada: earthquakescanada.nrcan.gc.ca/pprs-pprp/pubs…
Today’s little shaker north of #Montreal serves as a friendly reminder that #earthquakes occur across #Canada each and every day. If you feel shaking in 🇨🇦 you can check seismograms here earthquakescanada.nrcan.gc.ca/stndon/wf-fo/i… or see full 24-hour plots (thanks @IRIS_EPO) iris.edu/app/station_mo…
