Hello all, 'Chitan' volcanoe in southern chile just violently errupted. About 20km high ash/smoke plume injected up into sky. HOW DOES THIS AFFECT the famous southern observatory (sp?? Tiero de solo ??) europe/the americas maintain in Chiles mountains? Chile (up to this event) was thought to have about 500 active volcanoes, and over 2000 NON-ACTIVE volcanoes. Big shock is that this volcanoe had not errupted in 2000years, and WAS LISTED as one of the inactive volcanoes. How will the great southern observatory cope/ 'weather' this erruption/ and continue with reasearch?? charlie guevara NJ

There are a lot of variables to be considered. Wind patterns, sulfur content, and on and on. The settling out of particulate matter will be the biggest issue, as with any erruption.

Sometime around 1980 one or more volcanoes erupted in the northern hemisphere. In Buffalo, NY we were treated to teal blue sunsets and sunrises for a while. From what I remember about atmospheric circulation pattern the air masses tend to stay in whatever hemisphere they originate (meaning north and south hemispheres). Within a year things were pretty much back to normal.

Yup Ted ( I was Buff State, my spouse from Kenmore!), that was Mt.StHelena erruption about 1981?? Perhaps 'Google Maps' will show this event soon?!! I do hope the observatory fares well. charlie guevara NJ

They are not affected yet, as they are in the north of Chile, and the volcano is in the south, and the ash is blowing eastward. Give the ash time to circle the globe, then we'll see.

Mt. St Helens in 1980.
El Chichon (Mexico) in 1982 made for some interesting atmospheric effects, because it sent ash and gas high into the stratosphere.
I recall observing a total lunar eclipse in '82, which showed much darker umbral coloration on the northern half of the Moon, than the southern half.
