papers for volcanism Flashcards
1
Q
McGonigle 2017
A
- UV imaging provides higher temporal and spatial resolution volcanic gas emission rate data than any available previously
- volcanic activity is observed by measurements of geophysical signatures and through observations of gases released
2
Q
kantzas and Mcgonigle 2008
A
- it is estimated that 9% people live within 100km of a historically active volcano
3
Q
pering 2013
A
decrease in gas emissions can signify a build up in pressure and that a volcano eruption is likely
4
Q
Eichelberger 1995
A
- silicic eruptions tend to be of substantial volume with thick, slow-moving flows or domes, common pyroclastic flows, high explosive eruption columns and long repose periods between eruptions
- differences in appearance of eruptions is due to the high viscosity and lower mass diffusivity of silicic melts

Q
Grotzinger and Jordan 2014
A
- volcanic geosystem = the rocks, magmas and processes needed to describe the sequence of events from melting to eruption (diagram)
