lennium, the trend shown by recent earthquakes; that volcanic activity may be migrating into Lago Xolotlán where there already has been a major eruption that formed Isla Momotombito, must be considered and closely monitored. And if this isn’t enough, Masaya is another potential MDE volcanic system and there are indications that the magma system of the older Apoyo Caldera is still more or less intact even if it at present is dormant.
Finally, I would like to give my thanks to Dr Hans-Ulrich Schmincke for making his and his fellow researchers’ work available online. It is as exemplary as laudable.
