I detail, Vesuvius has 4 typical types of eruptions: 1. Plinian (such as the 79 AD Pompeii eruption): extremely large explosive eruptions producing several to several tens of cubic km of magma in a very short time. 2. Sub-Plinian explosive eruptions (such as the 1631 eruption). They are similar in style, but smaller than true Plinian events. 3. Strombolian and Vulcanian eruptions (several examples during the 1631-1944 period, e.g. 1906 and 1944). Such eruptions produce local heavy tephra falls, small pyroclastic flows, as well as large fire fountains and lava flows. 4. The smallest, but most frequent type of activity observed at Vesuvius is persistent Strombolian to Hawaiian-style activity that prevailed during much of the period between 1631 and 1944. This activity is usually limited to the central crater, and sometimes to flank vents. Lava flows and lava fountains have been frequently observed during such periods of activity.
