Mount Merapi's eruption in 1994?

Please could you tell me just the the actions of the volcano very mathmatically....So, I'd like to know how high plumes went, how far lava flowed....I am not particularly concerned about which rivers and villages were effected, at this point; Just the figures and technicalities will do. Please include things such as pyroclastic flows, lava flows, materials ejected etc etc...Thank you
