August 21, 1949 - a damaging M8.1 #earthquake (one of the largest ever recorded in North America) struck off #HaidaGwaii. Shaking was so strong that it was hard to stand. Felt across most of #BritishColumbia, parts of Alberta, WA, Yukon and Alaska www.earthquakescanada.nrcan.gc.ca/historic-his... ⚒️🧪

Another active fault on Vancouver Island - our new paper documents evidence for at least 3 Holocene earthquakes on the Beaufort Range fault
🌍The Beaufort Range fault is ACTIVE!
This right-lateral oblique Beaufort Range faulting occurs >100 km farther North than previously documented faults in the Cascadia forearc.

Really pleased to share our new paper in GRL, documenting evidence of multiple Quaternary surface-rupturing earthquakes on the Tintina fault in the Yukon.
