Roundup of Global Volcanic Activity:

Stromboli (Eolian Islands, Italy): An increase in activity occurred yesterday. Lava started to effuse from one or two vents at the base of and on the outer flank below the NE hornito. It is currently extending on the upper part of the Sciara and produces strong rockfalls that reach the sea. The seismic signal shows increased tremor and continuous rockfalls on the Sciara, as well as large explosion signals at intervals of approx 15-30 minutes.

Etna (Sicily, Italy): Activity has continued to increase with near continuous strong strombolian explosions from the New SE crater, but it seems that the climax of the paroxysm with sustained lava fountains is yet to come, possibly very soon. The tremor has reached higher levels than during most of the previous paroxysms, but still rises. Strong strombolian-type explosions, probably accompanied by effusion of small lava flows continued all night from the New SE crater and produced strong glow visible through the fog around the summit. Rumblings were heard in nearby villages, but fog and clouds have been preventing detailed observations. The tremor has risen to high levels comparable with those during previous paroxysms, then decreased a bit and seems now to increase again. This pattern looks very similar to the 12 April paroxysm, one which was preceded by a long phase of very strong explosions, that culminated in lava fountaining only after the tremor had reached its peak.

Santa María / Santiaguito (Guatemala): The rate and size of explosions from the lava dome has risen a bit when compared to the previous week. Some of the explosions, about 1-2 per hour, produce plumes almost 1 km high.

Pacaya (Guatemala): Weak strombolian activity from the Mackenney crater, well visible at night, continues and has been showing a gradual increase over the past days. This is also evident from the seismic recording. Some explosions can be heard in up to 3 km distance.

Fuego (Guatemala): The effusive eruptive activity continues to increase slowly. Two branches of the lava flow advanced to 500 m length towards the Ceniza and 400 m length to the Taniluyá canyon. Rockfalls from the flow fronts produce incandescent avalanches that reach the vegetation line. At the summit, strombolian activity has been weaker today, but continues with infrequent small explosion that eject bombs to 100 m height and produce small ash plumes. Activity has been increasing. Continuous stronger tremor today suggests an increase in effusion rate today. In INSIVUMEH’s report from yesterday, the new lava flow was 400 m long and produced small avalanches towards the Ash Canyon. The number of explosions rose to 17, producing gray ash plumes rising 600 m above the crater and drifting 8-10 km to the west and SW. They were accompanied by weak rumblings and locomotive-like degassing sounds. Incandescent material was seen rising 100-200 m at night.

Sangay (Ecuador): Brief ash emissions were reported observed through satellite yesterday around noon. Ash plumes rose to about 25,000 ft (7.6 km) altitude or about 2 km above the volcano. There is no ground monitoring, and only rarely direct observations become available from the very remote and difficult-to-access volcano. It is likely that usually small strombolian-type activity has been going on in the summit crater for some time. This activity usually goes unnoticed, unless explosions occasionally increase and produce more significant ash plumes such as yesterday.

Roundup of Global Volcanic Activity:

Etna (Sicily, Italy): Relatively intense strombolian activity and ash emissions continue at the New SE crater. INGV tremor data seems currently not to be available to see whether this is rising or not, and might be the beginning of another paroxysm. A steam and ash plume is rising about 1 km above the volcano.

Popocatépetl (Central Mexico): Activity is on the increase again at the volcano, which currently is producing a strong steam plume illuminated by the glowing lava in the summit crater. This rise in activity was preceded by a moderate explosion late on 24 April (which could not be observed due to cloud cover) and during yesterday, the rate of small to moderate emissions of gas-steam-ash rose to about two per hour.

Measles Virus Kills 100 Dolphins off Italian Coast

A viral strain that causes measles in humans has killed more than 100 striped dolphins that have washed up along Italy’s western coast from Tuscany to Calabria, as well as the island of Sicily so far this year.

The country’s National Institute of Marine Sciences said that the death rate among the striped dolphins has dropped abruptly this month, possibly indicating the outbreak has run its course.

The epidemic mostly affected young dolphins under the ages of 15 to 20 years.

Volcanos

Roundup of Global Volcanic Activity:

Stromboli (Eolian Islands, Italy): Activity remains elevated, with magma filling the NE crater to the rim and sometimes relatively strong explosions. No significant new overflows have occurred since the last update.

Etna (Sicily, Italy): Ash emissions and strombolian activity has continued since the last paroxysm and increased in frequency yesterday and today. The tremor signal has remained low, not suggesting that the volcano is in for another paroxysm at the moment, something quite different (so far) from the activity preceding the past paroxysms.

Kizimen (Kamchatka): The slow growth of the lava dome continues with no changes reported by KVERT: Moderate seismic activity, incandescence of the volcano summit, hot avalanches on the western and eastern volcanic flanks, and strong gas-steam activity accompany this process.

Tolbachik (Kamchatka): The eruption continues to produce lava flows from the Southern fissure on Tolbachinsky Dol. KVERT reports strong tremor at a very gradually decreasing rate over the past weeks.

Colima (Western Mexico): Activity consisting of rockfalls, small pyroclastic flows and weak explosions continue with little changes during the past days.

Popocatépetl (Central Mexico): A moderate-sized explosion occurred yesterday, producing an ash plume rising 1.2 km and throwing incandescent bombs to 500 m distance on the outer flanks of the volcano. Small explosions occur at an average rate of one per hour and a large steam plume is often rising to about 1 km above the crater. Incandescence continues to be visible at night at the crater. Small volcano-tectonic earthquakes have been relatively frequent during the past days as well.

Fuego (Guatemala): This morning, a new lava flow emerged from the crater and started to flow down the southern flank towards the Trinidad canyon, reaching a length of 300 meters. Explosions continue and produce ash plumes rising to 4-4.2 km altitude (300-500 m above the crater), generating weak to moderate rumbling avalanches. INSIVUMEH warns that this activity could increase towards a more intense eruptive phase in the coming days, with larger explosions, and possibly pyroclastic flows. The other active volcanoes in Guatemala have not changed in their activity: Pacaya has weak strombolian activity, while the lava dome of Santiaguito, relatively calm these days, produces occasional weak explosions and weak avalanches from the active flows descending the flanks of the dome.

Telica (Nicaragua): The earthquake swarm shows no sign of weakening. The frequency of quakes remains high, although most are very small in magnitudes.

San Cristobal (Nicaragua): Weak continuous volcanic tremor has slightly increased during the past days at the volcano.

Nevado del Ruiz (Colombia): Earthquakes and tremor have decreased to low levels again. Probably, the latest magmatic intrusion has come to an end (with no significant eruption).

Reventador (Ecuador): Activity has decreased lately, with only occasional small explosions and weak steaming observed. The MODIS data show no longer a hot spot, suggesting that lava effusion has more or less stopped.

Tungurahua (Ecuador): Activity (both internal and external) has remained low.
