Measure
change of the slope
Tiltmeter
Non explosive, low viscosity less 50% silica
basaltic magma
I exit from the side, coming from the main
side vent
I'm broad, I have gently sloping sides and I have near circle base, I'm not formed from explosive eruption
Shield Volcano
ways in which I can harm
acid rain, destruction to plants, starvation
Creepmeter
andesitic magma
I act like a furnace, hot and boiling, I create churning
Magma chamber
I'm formed by layers of hardened chunks of lava. I'm formed from violent explosive eruption alternating with layer of sediments
I'm a composite volcano
Pieces of solidified lava, rock and ashes thrown from the air during violent eruption
analyze light to reveal information about the substance
Spectrometer
explosive, high viscosity more 60% of silica
Rhyolitic magma
I have empty magma chamber, i cannot erupt
extinct volcano
I have steep sides formed quickly when cinder cores are ejected on the air
I'm cinder cone volcano
I'm a volcano hole and I form when the summit of the volcano collapses in empty magma chamber
I'm a caldera
measure vibrations
seismometer
thrown upward out volcano
lava bomb
I'm quiet since some time but... could erupt again, eh, eh eh!
dormant volcano
Our names are Vesuvio, Mt St. Helena, Fuji, Etna, Krakatoa we are in good company, how is called our "gang" :)
composite stratovolcano
I can move, you can see chain of past of myself. Where I can be seen? What you can predict?
Yellowstone calderas. Predict future eruption
measure heat but not for checking fever LOL
Thermal Imager
rolling ash cloud, extreme heat, 100 mile spread, high pressure, poisonous gas
Pyroclastic flow
I'm usually at convergent / divergent boundary, I created the first atmosphere, I help carbon cycle, creates fertile land
I'm a V O L C A N O :)
Our names are Mauna Loa and Killua
Shield volcano
I can be away from a plate boundary but I need to be at a thin spot of the lithosphere
I'm an hot spot volcano
