volcanic activity Flashcards
product of effusive eruptions - LP
lava plateaux - when basic magma erupts from multiple fisstures
vast areas can be coverd by free flowing lava, thease events are known as flood basalts, no large scale flood baslats have taken place in the last 50 million years
product of effusive eruptions -SV
sheild volcanos - effusive eruptions I found that diverging plate boundaries because his plate boundaries coincide with mid ocean ridges.
most eruptions occure on sea floor
4 stratgies to try and stop lava flow
bomb it
cool it
build a barrier
add concrete
ways to predict volcanos
study changes in sisemic activity
ground deformantion
gas emission changing
however thease are very short term predictions, the most desired infomation is not avaliable
