Italy / Sicily , Etna :

After a pause in the explosive activity at Etna’s summit craters, this morning the volcano has resumed emitting gas and ash in a discontinuous manner. For the moment, this activity is rather modest compared to that of last week, and it is occurring from the Voragine crater and possibly also from the Bocca Nuova. There are no variations in the monitored parameters: for example, the volcanic tremor amplitude remains at low levels.

The smoke plume of the Sicilian volcano returns. After a few days of explosive activity stagnant in the region of the summit of Mount Etna, the volcano resumed yesterday to emit ashes and gas in a very discontinuous manner. As explained by the experts of the volcano department of the National Institute of Geophysics and Volcanology, this is for the moment a relatively modest activity compared to that of the previous week, from Voragine – which is the most central of the craters of the summit, and also of the Bocca Nuova. « After 10 days of ash emission – explains Marco Neri, Vulvologist of Ingv – of Voragine, now it is the Bocca Nuova, almost a sort of natural valve for the active volcano, which is constantly monitored ». The little clouds of ash disperse quickly in the air, captivating the audience (Isabella Di Bartolo, photo by Giò Giusa)

Philippines , Taal :

TAAL VOLCANO BULLETIN 24 June 2019 08:00 A.M.

Taal Volcano’s seismic monitoring network recorded sixteen (16) volcanic earthquakes during the 24-hour observation period. Field measurements on 20 June 2019 at the eastern sector of the Main Crater Lake yielded an increase in water temperature from 33.4°C to 34.0°C, a decrease in water level from 0.14 meter to 0.08 meter and an increase in acidity from a pH of 2.91 to 2.83. Ground deformation measurements through precise leveling surveys from 18 – 27 March 2019 indicated slight inflation of the edifice consistent with recent results from continuous GPS data.

Alert Level 1 remains in effect over Taal Volcano. This means that hazardous eruption is not imminent. The public, however, is reminded that the Main Crater should be strictly off-limits because sudden steam explosions may occur and high concentrations of toxic gases may accumulate. The northern portion of the Main Crater rim, in the vicinity of Daang Kastila Trail, may also become hazardous when steam emission along existing fissures suddenly increases. Furthermore, the public is also reminded that the entire Volcano Island is a Permanent Danger Zone (PDZ), and permanent settlement in the island is strongly not recommended.
