Mt. St. Helens Eruption of 1980

I remember this happening...  Glad I wasn't directly downwind!

Video about Russian Submarine K-141, Kursk

Wiki sez:

"Kursk, full name Атомная подводная лодка «Курск», which, translated, means the nuclear-powered submarine "Kursk" [АПЛ "Курск"] in Russian, was a Project 949A Антей (AnteyAntaeus, also known by its NATO reporting name of Oscar II). It was named after the Russian city Kursk, around which the largest tank battle in history, the Battle of Kursk, took place in 1943." 

She sunk August 12, 2000 with all hands.  Some survived for a time at the bottom of the ocean. I cannot imagine a worse way to die, both for the men and for their families.

Found this video online and thought it was a fitting (if sad) testament to the men.

Geological Cataclysm - The Missoula Floods

Western Washington state has a very interesting, if barren, landscape.  It took a fascinating geological detective story to understand how it got this way.  What is amazing is how awesome and violent the process was that produced this landscape!

The image below shows an area known as the Channeled Scablands.  Spokane, Washington is the city at the upper right.

Geological Cataclysms - The Cascadia Earthquake of 1700

This is another successful and impressive geological detective story.

The largest earthquakes in the world occur at subduction zones.  A subduction zone is where one continental plate is being pushed underneath another.  Only a subduction zone can generate an earthquake greater than magnitude 8.5 (a "great earthquake")
