Hello James -
I can query the db to pull some of this information out for you, but we don't store all of it. I'll send a separate email with tables. (This email reply system doesn't permit attachments.)
Additionally, there are important caveats.
--many events are suspected
--time periods where there is less than 90 days between eruptive activity at a volcano get lumped into one eruption. For example, the dozens of small explosions and several domes at Cleveland from mid-2011 through Jan 2013 are ONE eruption. There is one eruption at Trident from mid-1950s until mid-1970s.
--I store only the max VEI
--I used to store region, but they were just for handy display on maps. Now that we can do dynamic maps, I don't track regions anymore. I've learned everyone would prefer to draw his/her own boundaries, based on whatever criteria are most important to him/her.
--volumes: For the volcanoes that have this, it's in a giant text field about the eruption, not in a field I can easily pull out. There aren't many. (couple dozen, max. I can give you the text fields - typos and all - and you can find them. Usually at the very end of the field.)
--I have no idea what you might mean by "intensity". We use VEI (as assigned by the Smithsonian Institution Global Volcanism Program)

I am a graduate student at Eastern Washington University. I want to download the data for volcanic eruption events from the Alaska region but can not find a way to do so. The data is going to be used for a class data mining project. We need eruption data from 1800 to present. The data fields we are looking for are below. Please let me know how to obtain this data.
Volcano Name
Latitude
Longitude
Region Sub-region
Volcano Type
Eruption start date
Bulk deposit volume
Bulk DRE volume
Magma Type
Magnitude
VEI
Column height Max
Intensity Max
