A second way an earthquake can cause an eruption is by unlocking a fault. A locked fault does not give way easily, and will not allow magma to intrude. But unlock it, and the stress reduces ...

The same seismic mapping has also shown that there are two somewhat shallow reservoirs within the caldera. One (‘A’ on the map) is located underneath the bay at some 2.5 km depth, and the other (‘B’) ...

The area from well north of Rome down to and including Naples is one that has seen a great number of very large, ignimbrite depositing and caldera forming eruptions. The 13 x 19 km Lago di Bolsena ...
