Oregon rethinks tsunami's reach - OregonLive.com: "At least 20 times in the past 10,000 years, a massive rift in the seafloor off the Oregon coast known as the Cascadia subduction zone has torn apart, generating earthquakes anywhere from magnitude 7.0 to 9.0. It's an area that looks a lot like the seafloor near Sumatra, which generated the 9.0 magnitude quake the day after Christmas in 2004. It was that quake that prompted Oregon's state geologists to take a second, closer look at the 1995 inundation maps."
