Potential for Mega-Tsunami Threat to Nearly Double by 2100

Buzzline

Research featured in the Proceedings of the National Academy of Sciences indicates that the Cascadia Subduction Zone located off the Pacific Northwest may experience a significant rupture with a 15% likelihood within the next 50 years, a figure that escalates to 29% by the century's end. Lead researcher emphasizes that rising sea levels coupled with land subsidence from earthquakes could hinder recovery efforts today and potentially make numerous coastal areas uninhabitable by 2100. The study references a recorded mega-tsunami that impacted Lanai island in Hawaii approximately 105,000 years ago, and highlights that the last major rupture in Cascadia occurred in 1700, producing a quake estimated between 8.7 and 9.2 in magnitude, generating tsunami waves that reached Japan.
