| These new vents remained phreatomagmatic until 25 July, when the activity changed for 5 days to Strombolian and effusive. |
|
| We prove that Strombolian signals, both tremor and explosions, in the high frequency band, are similar in time domain. |
|
| Phreatomagmatic to strombolian cones, which are the first eruptive vents of the horizontal series, are intercalated at the contact. |
|
| Lava fountaining has given place to sporadic strombolian activity at the row of the upper vents. |
|
| They are basaltic flows rich in zeolites and phenocrysts, and intercalated with strombolian and phreatomagmatic deposits. |
