A nightmarish scenario for the Pacific Northwest has received a significant update.
Researchers have long warned about the potential for a powerful earthquake in Oregon and Washington state that could result in widespread devastation, including critical infrastructure damage and a tsunami threat.
A recent report published by the Proceedings of the National Academy of Sciences highlights the risk of sudden coastal subsidence, which could lead to rapid flooding post-earthquake.
The report emphasizes the possibility of coastal ground dropping rapidly after a massive earthquake, resulting in a significant flood risk. Researchers have warned that in some areas, the ground could sink up to 6 feet, similar to what occurred during the 1964 earthquake in Alaska.
The study envisions a grim scenario for the Pacific Northwest, with the next great Cascadia subduction zone earthquake potentially causing sudden coastal subsidence of up to 2 meters, leading to increased flood risk for local communities.
The report also underscores how climate change will further exacerbate the risk of earthquake-induced flooding in the region over time.
While the probability of such a catastrophic earthquake in the next 50 years is relatively low at 15%, experts urge residents to prepare for the worst. The importance of emergency preparedness, including having essential supplies like a flashlight and a charged phone, is emphasized.
Furthermore, experts stress the significance of building strong community ties as a crucial aspect of disaster preparedness, as neighbors can provide essential support in times of crisis.
