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

Really pleased to share our new paper in GRL, documenting evidence of multiple Quaternary surface-rupturing earthquakes on the Tintina fault in the Yukon. doi.org/10.1029/2025... @faultydata.bsky.social @earthquakeguy.bsky.social @thatfaultguy.bsky.social @tephrafan.bsky.social
