The volcanic field at Laguna del Maule on the Chile-Argentina border contains 36 post-glacial domes and coulees, with total erupted volume of 40-50 cubic kilometers. There were at least another 29 explosive eruptions during this time. Recent and large uplift raises many questions: what causes the uplift? is there reason to expect a new eruption? why does the magma erupt around the lake? what is the origin of the compositional diversity? These and more questions were discussed in January 2018 at the AGU Chapman conference on merging geophysics, petrochronologic and modeling perspectives of large silicic magma systems.
