Tsunami Workshop 2014

​​Map of tsunami travel times in the north Pacific associated with the Great Alaska Earthquake of 1964.

On occasion of the 50th anniversary of the 1964 Alaska earthquake and tsunami, Ocean Networks Canada and the Port Alberni community co-hosted a 2-day technical workshop. The workshop provided a brief overview of tsunami models, tsunami risk for the coast of BC and the technology available for event detection and alerts. Structured discussions among a broad range of sectors followed with the goal of identifying technological requirements for real-time tsunami forecasting for British Columbia’s coastal areas.

About the Earthquake & Tsunami

On 27 March 1964 a magnitude 9.2 mega-thrust earthquake struck Alaska's Prince William Sound. This powerful earthquake, 2nd largest in recorded history, generated a tsunami, which devastated coastal areas from Alaska to Califormia. 139 lives were lost and $2 billion in damages sustained in the US. Port Alberni, BC suffered the greatest impact in Canada; there was no loss of life, but the town suffered extensive damage. 55 homes were washed away and another 375 damaged. Total estmated losses to Vancouver Island are around $50 million (2005 dollars).
