 Strombolian explosions, Stromboli Stromboli and its activity is some of the most charismatic and beautiful you will ever see, especially at night (my next post)! What visit to Stromboli would be without multiple attempts at trying to capture that perfect explosion (which many many tourists do during the day and night). During the day, explosions were ash-rich and the day-light prevents from seeing the majority of that amazing incandescence. The photo on the right shows a typical explosion from one of the summit vents, note how the ash and larger blocks are falling down the flanks and onto the Sciara del Fuoco. The Sciara del Fuoco is a large collapse feature on the island and presents one of the major hazards for tourists and locals alike. Inset (right) is another explosion from the same crater where you can see the hints of incandescence and the hot nature of the rock. Below is a real time video of an explosion from the same crater. In it you can see the initial thrust of the explosion and convective rise of ash into the atmosphere which eventually disperses as inertia is lost and mixing with cooler air occurs. The activity is fairly frequent, every 5-15 mins or so dependent on activity levels, so it is quite easy to get snap-happy if you have a lot of time on the summit! Comments are closed.
