Reminders of Oregon’s Geologic Past

We often enjoy posting Yahoo’s Who Knew? videos on this blog (who knew that they are produced by the same company that does The Office and Family Guy?). The latest takes a peak back a year to the Icelandic volcanic eruptions at Eyjafjallajökull that disrupted air traffic across Europe. If you watch the video, you learn that if we look farther back there was a much bigger eruption a lot closer to home…

Last week scientists also announced that the history of the Yellowstone Supervolcano not only can be traced back to Oregon, but that the underground chamber of molten rock fueling it still extends close to the border.

We keep volcano preparedness tips on our website. It is important to note that a massive event such as Mount Mazama (Crater Lake) or a Supervolcano eruption in our area is unlikely to occur, although ‘smaller’ events similar to Mt. St. Helens are a possibility and could cause disruptions similar to Eyjafjallajökull.
