AI Thread Summary
A powerful storm originating from the remnants of Typhoon Nuri is impacting Alaska, primarily affecting the Aleutian Islands with minimal damage. This storm is expected to drive a significant cold air mass into the continental United States, resulting in temperatures that could drop 20 to 40 degrees below average in various regions. The National Weather Service has issued warnings for areas near the Columbia River Gorge, anticipating very windy conditions and potential power outages, particularly in Corbett, Troutdale, and Gresham. Travelers on Interstate 84 and Interstate 205 should exercise caution due to strong winds and hazardous conditions. The situation calls for preparedness as the frigid weather and winds are set to intensify in the coming days.

Alaska storm brings frigid weather to swath of US
http://news.yahoo.com/alaska-storm-pushing-cold-air-toward-lower-us-090835038.html

JUNEAU, Alaska (AP) — A massive storm fueled by the remnants of Typhoon Nuri did not do much damage in Alaska's sparsely populated Aleutian Islands, but forecasters say it's anchoring a system that will push a frigid blast of air into the mainland United States and send temperatures plunging early this week.

Parts of the lower 48 states could see temperatures between 20 and 40 degrees below average, the National Weather Service said Sunday.
This is like the hurricanes that hit the US and head off NE past Maine and Nova Scotia/Newfoundland toward Ireland and the UK.

Typhoon Nuri (2014) not to be confused with Typhoon Nuri of 2008

EXPERIENCE VERY WINDY CONDITIONS TUESDAY AND WEDNESDAY. RESIDENTS
NEAR THE MOUTH OF THE COLUMBIA RIVER GORGE...PARTICULARLY IN
CORBETT...TROUTDALE AND GRESHAM SHOULD BE PREPARED FOR POWER

Thread 'The Secrets of Prof. Verschure's Rosetta Stones'

(Edit: since the thread title was changed, this first sentence is too cryptic: the original title referred to a Tool song....) Besides being a favorite song by a favorite band, the thread title is a straightforward play on words. This summer, as a present to myself for being promoted, I purchased a collection of thin sections that I believe comprise the research materials of Prof. Rob Verschure, who at the time was faculty in the Geological Institute in Amsterdam.

Thread '(Unprecedented?) Cluster of earthquakes in Greek islands'

These last days, there is a seemingly endless cluster of rather powerful earthquakes close to the islands of Santorini, Amorgos, Anafi, and Ios. Remember, this is a highly volcanically active region, Santorini especially being famous for the supervolcanic eruption which is conjectured to have led to the decline of the Minoan civilization: https://en.m.wikipedia.org/wiki/Minoan_eruption To grasp the scale of what is happening, between the 26th of January and the 9th of February, 12000...
