Correct answer - 120 for Thymine.
Why? - 320 Nitrogen bases. 
Cytosine = 40, Cytosine = Guanine.
Therefore Guanine = 40. 
320 - 80(Cytosine and Guanine)
240. 
Adenine and Thymine = ? 
Adenine = x and Thymine = x.
2x = 240.
X = 240/2
X = 120.
Adenine 120, Thymine = 120, Cytosine = 40 and Guanine = 40. 
        
             
        
        
        
Answer:
 pyroclastic flow is a fast moving current of hot gas and volcanic matter that flows along the ground away from a volcano at high velocities.
Hotspot is volcanic regions thought to be fed by underlying mantle that is anomalously hot compared with the surrounding mantle
caldera-a large volcanic crater, especially one formed by a major eruption leading to the collapse of the mouth of the volcano.
tephra-rock fragments and particles ejected by a volcanic eruption
epicenter-the central point of something, typically a difficult or unpleasant situation
fault-an extended break in a body of rock, marked by the relative displacement and discontinuity of strata on either side of a particular surface
surface waves- mechanical wave that propagates along the interface between differing media 
body waves-A body wave is a seismic wave that moves through the interior of the earth, as opposed to surface waves that travel near the earth's surface. P and S waves are body waves.
