Eruption updates & news from Stromboli:
Stromboli volcano (Italy), activity update: strombolian activity returns to summit craters
As Andrea Ercolani reports from Stromboli, the "normal" strombolian activity seems to be returning to the summit craters since early July.
After the effusive eruption which ended on 4th of April this year and a powerful vent-clearing explosion on 15 March, there have been deep-seated explosions ejecting black ash clouds since May. In July, these have beomce more regular and it seems that the magma level inside the vents has been rising and there could soon be visible lava ejections again.
Access to the summit is still restricted and visitors may only climb up to 400m elevation accompanied by an authorized mountain guide, but it is being discussed wether new rules to allow access to the summit will be established. This will be communicated here as soon as it happens.
The lava flow from Stromboli volcano stopped today.
Whether this is the end of the effusive eruption that had started 5 weeks ago and heralds the beginning of a new cycle of summit activity is still unclear.
The lava continues to flow on Stromboli. Three branches of lava flows originate at the 420 m vent on the Sciara del Fuoco, two of which still reach the sea.[meer...]
Today, 21 March, tremor has decreased and thermal camera observations show that at least one of the two branches were no longer alimentated and cooling. ... [meer...]
On 15 March at 21.37 local time, a powerful explosion occurred from the summit craters of Stromboli, similar but much weaker than the event on 5 April 2003. Incandescent bombs were thrown onto the flanks of the volcano and created small bushfires. Ash fell on the inhabitated centers of the island, but nobody was killed or injured during the eruption.
The monitoring network registered a slightly increased flux of lava from the 400 m vent immediately prior to the explosion. As a security measure, access to the volcano has been reduced frm 400 m to 290 m elevation.
The lava flow from the 400 m vent at the eastern sector of the Sciara del Fuoco is still active.[meer...]
