"7.3 magnitude earthquake rattles Alaskan island, prompting tsunami advisory" by ABC News @abc - NOAA briefly issued a #tsunami warning for M7.3 #earthquake vicinity in Alaska's Aleutian Islands, later reduced to advisory and then cancelled when a tsunami wasn't observed. https://abcnews.go.com/US/72-magnitude-earthquake-rattles-sand-point-alaska-prompting/story?id=123814339 #quake #geology
Rule of thumb for estimating #tsunami risk from an undersea #earthquake magnitude:
M7+ -> localized tsunami possible
M8+ -> regional tsunami likely
M9+ -> ocean-crossing tsunami expected
