Volcanic tremor continues at background levels, with no eruptive activity seen, for the 5th full day in a row, with each passing day of no activity increasing the likelihood that the eruption is finished for good, although a reactivation cannot be ruled out. PEVOLCA is keen to stress there is still large dangers from the temperatures of the lava flows and the associated gases. Small remnants of lava flows breaking out from lava tubes have still been observed in the south, associated with flow number 11. Furthermore, it is anticipated that gas levels may lead to entry into the southern parts of the evacuated zones being halted sporadically in the next days.

Volcanic tremor continues at background levels with no change and there remains no eruptive activity on the surface, apart from slight degassing from the main craters and areas where the roofs of lava tubes have collapsed. PEVOLCA again was keen to stress that the legal emergency situation and red traffic light are still maintained, as are the Civil Protection measures that have been in place since the start of the eruption.

For the third day, volcanic tremor continued at background levels and there was no eruptive activity on the surface, apart from slight degassing from the main craters and areas where the roofs of lava tubes have collapsed. However, PEVOLCA was keen to remind people that a high risk still exists, and that civil protection measures, exclusion zones and evacuation zones are being fully maintained. People who access these areas must always be accompanied by personnel with air quality measuring equipment.

Throughout the 15th, volcanic tremor continued to be at background levels and there was no eruptive activity on the surface, apart from slight degassing from the main craters. However, PEVOLCA was keen to remind people that a high risk still exists, and that civil protection measures, exclusion zones and evacuation zones are being fully maintained. To start thinking about the end of the eruption, the current state of the volcano must be maintained for at least 10 days.

Since the cessation of volcanic tremor on the evening on the 13th, it has remained at background levels now for more than 24 hours. No surface activity is seen from the main cone, and the lava flows on the surface are largely inactive. PEVOLCA say this may represent a sign of ‘exhaustion’ of the eruptive process but refuse to rule out a restarting of activity. The number of earthquakes increased yesterday to 91 events, peaking at M3.2. However, some of this increase is due to the fact that there is no tremor, as 56 lower magnitude events (

The volcano has entered a new eruptive phase, which began with the intensification of tremor on the 12th. Since then, the tremor has been extremely variable, with peaks throughout yesterday coinciding with intense phases of explosive strombolian activity and ash emission, producing strong and high eruption columns. Yesterday evening however, tremor signals ceased entirely, and this remained the case until this morning when a brief spike in tremor has been seen. In the evening, tremor again ceased completely, as did activity from any of the vents. The number of earthquakes increased yesterday to 71 events, peaking at M3.4. However, some of this increase is due to the fact that when there is no tremor, more lower magnitude events (

From midday yesterday, a strong intensification in the seismic tremor occurred, and this was seen on the surface as an intensification of activity. Strong explosive strombolian activity with ash emission and lava fountaining from multiple vents in the main cone was seen throughout the day, and although the intensification decreased later into the evening, the activity remained above what has been seen in the past week or so. Tremor values have been extremely variable, and remained at elevated levels throughout the night. However, aside from a slight widening of the front of flow 9, the lava flows continue to follow the same paths from the last few days over previous flows.

The surface activity and emission of lava remains concentrated around the effusive vents to the west of the main cone, which emits lava flows that continue to travel over previous flows, in the central and southern areas of the lava flow field. Generally, activity in the main cone has been limited to weak strombolian activity, degassing and ash emission from the southeast vent, although there are still periods of more intense ash emission and strombolian activity. PEVOLCA has been keen to stress that although the emission of lava is reduced relatively to previous days and weeks, the danger from volcanic gases is just as persistent as ever.

There has been little variability in the eruption in the last 24 hours, with it continuing to show strombolian activity and ash emission from several vents in the centre and southeast of the main cone, and effusive activity from vents to the west of the main cone. The lava flows continue to feed mostly flow 9, but some of flow 11 as well, although in the last 24 hours no new land has been affected by the lava flows.

The eruption enters its 82nd day, still showing mixed strombolian activity and ash emission from several vents in the centre and southeast of the main cone. There also remains active effusive vents located to the west of the main cone emitting fluid lava flows. The only current active lava flows are those feeding flow 9, which represents the southern end of the lava delta and the flow occupying the lava delta (fajana) from the 1949 eruption. The lava flow to the south that was affecting new ground however appears to have become inactive. The cracks seen in the secondary cone have been confirmed to have produced small landslides modifying the morphology of the cones, although this has not affected broader edifice stability.
