I would like to see these records. Yeah, 500 years is a good amount of time for pressure to build, but I don't buy a regular occurrence. If we do get a big one here, it will fuck some shit up.PORTLAND, Ore. - Scientists are urging city planners and emergency services to get ready for the Big One.
They say an earthquake of magnitude 9.0 or greater is overdue for the Northwest, and that the area is not prepared for the aftermath of such a powerful temblor.
Using geological records and historical data, scientists estimate that a huge quake hits the area every 500 years or so. They added that the last big quake on the fault line was over 500 years ago.
