Where transitions in eruptive style at the same volcano occur over several eruptions, these changes may be closely linked to the mechanism that triggered the eruption. A common example of eruptive activity driven by processes at depth involves injection of new magma into a subvolcanic reservoir9,10...
For example, if a shallow magmatic system is supplied with magma at an intermediate flow rate, the eruption will be slow and effusive until the chamber over-pressure becomes too large. An explosive eruption then relieves the overpressure and an effusive eruption style resumes. We suggest that ...
After the end of the 2007 effusive flank eruption at Stromboli volcano, explosive activity at the summit craters displayed a gradual shift from NE to SW, as shown by ash emissions and the thermal signature of the crater floor. The sequence of events (Table 1) is evidenced by variations of ...
A response narrative is a description of the response actions taken because of the eruption. Anyone affected by the eruption could have undertaken response actions. For example, a scientist may hold a press conference to inform the public about the eruption, a government official may call an evac...
The transition from explosive to effusive eruptive regime: The example of the 1912 Novarupta eruption, Alaska The shift from explosive to effusive silicic volcanism seen in many historical eruptions reflects a change in the style of degassing of erupted magma. This... NK Adams,BF Houghton,SA F...

This eruption provided a clear example on how the strategy of integrating in near-real-time geophysical information can pinpoint the transition from explosive to effusive activity of the shallow volcanic system at Stromboli.doi:10.1016/j.jvolgeores.2009.02.011...
The volcanic activity that built up the Monte dei Porri stratocone (Salina Island) was reconstructed using new stratigraphic data, which allowed seven eruption units to be distinguished. Alternating Strombolian/Vulcanian to sub-Plinian/Plinian explosive and effusive activity emplaced fall and pyroclastic ...
