Kamchatka is an example of where there are a large number (50+) of active volcanoes in close proximity. http://www.volcanodiscovery.com/volcano-tours/volcano_news/kamchatka/?&L=1 Jim Arnt, you are right and I was over-generalizing.

It just seems like a bad idea if you ask me.</blockquote> How come people move to places where hurricanes can and do hit every year, sometimes several times a year? Why do people move to where Tornadoes are prevalent? Nowhere is really safe from, extreme weather. Colorado gets major snow which can and does kill people, deserts have their own sets of problems, and an earthquake can hit anywhere as well. I moved to the Puget Sound area because it's very beautiful, and because my dad retired there ;). There are multiple potential volcanoes in the area, but I live far enough from any of them that they would not present a problem to me. And prevailing winds are westerly, so most ash and smoke would blow in the opposite direction, meaning areas NOT prone to volcanoes would suffer worse effects than I likely would.

I'm very familiar with lenticular clouds, and they tend to be stationary with a finite dry line just past the point where the compression wave ends. The sat photos of Ross Island don't look like this, but look more like the result of steam that has turned to ice crystals and been blown downwind. The official "explanation from MEVO's director is "cirrus blowoff". Cloud show

See topo map below. Typically, a group of volcanoes like this are formed by a single mantle plume migrating over time. That means only one of them is over the mantle plume at any time and only that one will erupt. http://upload.wikimedia.org/wikipedia/commons/a/aa/RossIslandMap.jpg There appear to be 4 volcanic cones on Ross Island.

Sitting in traffic in Algeciras, Spain and looking across the bay at the Rock of Gibraltar with a north wind blowing, I watched compression/expansion clouds forming just to the lee of the peak and streaming south, dissipating out over the Straits. Camera not handy, of course, but I do not recall ever seeing the rather elegant example of compression/expansion cloud formation described before. Any of you meteorologists remember seeing it in a text anywhere? I have observed a similar phenomenon under much different conditions.
