[UVic Science @UVicScience]

UVic professor @schaefferaj is part of a five-year program studying earthquake hazards in the Canadian pacific. The program has the biggest deployment of Canadian broadband ocean bottom seismometers in Canadian waters.

First two of the Canadian NFSI OBS being deployed off Canada's west coast, to better understand earthquake hazard throughout the region. Great start to the 5-year @GSC_CGC @UBCeoas @UVicSEOS and @dalhousie NFSI collaboration!

@SchoolShake @raspishake This plot shows signals from the 4 booms recorded at 14 stations, from 10 km to 55 km (top to bottom). Another interesting little find for @SchoolShake! (@GSC_CGC @UVicSEOS @HakaiInstitute) See https://t.co/Ng8kDXJ81s for a station map.

@earthquakeguy @GSC_CGC And now look how many stations are recording in the greater #Victoria region @crd_bc! The high density in #Victoria is thanks to @SchoolShake @raspishake, deployed by @GSC_CGC Pacific and @uvic @UVicScience @UVicSEOS

📢Postdoc opportunity in seismology!
Keen to uncover the mantle dynamics beneath Iceland? Keen to work on ocean bottom seismic data?
Sergei Lebedev and myself offer this in Cambridge https://t.co/LGzDuuTTPb
Please share!

@raspishake #citizenscience community, the @SchoolShake program would love to talk with any shakers running a Raspberry Shake on Vancouver Island, the Lower Mainland, Sea to Sky, Squamish, Whistler, Puget Sound, San Juan and Gulf Islands. Please reach out to us!

[Andrew Schaeffer @schaefferaj]

@LisaNykolaishen @earthquakeguy @alisonlbird Did you ask them to keep digging?!

[Andrew Schaeffer @schaefferaj]

@PaulaJohanson @SchoolShake @UVicSEOS @GSC_CGC @HakaiInstitute @raspishake Thanks for submitting your felt report @PaulaJohanson , that is valuable information for us! This swarm is really quite interesting. Such swarms are common generally, though new for this location. I would tell your friend these are likely unrelated to the big one :)

[Andrew Schaeffer @schaefferaj]

Fascinating swarm of small earthquakes north of Sooke, BC today. More than 30 events most <M1 and quite shallow. These detections were made possible by the @SchoolShake network run by @UVicSEOS, @GSC_CGC and @HakaiInstitute, using @raspishake instruments. (1/3)

[Andrew Schaeffer @schaefferaj]

@VictoriaNews this is a continuation of the shallow inland earthquakes reported yesterday. The rest of these weren't felt like the early M2 were, but likely part of the same sequence.

[Andrew Schaeffer @schaefferaj]

This small sequence of events serves as another reminder of the need to be prepared. Well timed for #EmergencyPreparednessWeek #EPWeek2023! Checkout our @SchoolShake webpage https://t.co/4kTqf1nTE9 to learn more about the program, and view our earthquake map and stations. (3/3)

[Andrew Schaeffer @schaefferaj]

The largest event in the sequence was an M2.1 which occurred at 9:34 pm May 7th, and was reported as felt. The bulk of the events occurred during a 4.5 hr window between 9:30 pm May 7th and 2:00 am May 8th. (2/3)

Looking good @dpettsy !

[Daniele Regis @Daniele_R1]

Presenting #GEMGeonorth and #TGI6 results #AGU22. Great discussions and feedback! @GSC_CGC @dpettsy

[Andrew Schaeffer @schaefferaj]

@bchydro Thanks! Power came back on already!

[Andrew Schaeffer @schaefferaj]

@bchydro is there a new outrage near quadra and the pat bay? All the power just went off in the house.

[SchoolShake @SchoolShake]

4 more schools are starting off the school year with a @raspishake. Welcome EMCS in Sooke (RE0FF), St John's in Shawnigan (RD862), @SD63NSaanich (R01DF) and @yourSMUS (RF395). Looking forward to working with all of you and your students!

[Roger MacLeod @Roger_MacLeod]

It was a pleasure to work with the incredible Jalal Norooz Oliaee & Chase Sun from the Metrology Research Centre @NRC_CNRC. We used their in-house developed sensors to measure & map natural sources of #methane. Jalal makes final preparations before a day of surveying. @GSC_CGC.

[Andrew Schaeffer @schaefferaj]

After several years not making it up north, it is a pleasure to get back up to the Arctic again with the @GSC_CGC, especially with all this sunshine!

[Gregor Craigie @GregorCraigie]

This is @faulty_data showing me one of the Raspberry Shake instruments (miniaturized seismometers) being installed in Vancouver Island schools to further #earthquake research and education. If you’d like one in your school, check out: https://t.co/KcD2Wq5Dce
