The National Institute of Geophysics and Volcanology, Etnéan Observatory, reports that at 10.33 UTC hours on 6 July, there is a sudden increase in the average amplitude of the volcanic tremor. INGV staff observed a Strombolian activity in the field at the new crater southeast of Etna, with products falling down the sides of the crater.

After the paroxysm that hit Stromboli this week, all measuring stations affected by pyroclastic flows and fires are again operational, following the intervention of specialists in charge.
A Sentinel 2 image shows that much of the vegetation was burned or covered with ash, especially towards Ginostra; the lava flow, during cooling in the Sciara del Fuoco, is distinct.

In the last 24 hours, 22 low-level exhalations have been reported at Popocatépetl, accompanied by low ash emissions.
In addition, three explosions occurred : two, of low intensity, were recorded at 4:14 and 7:58, producing columns of ash in small quantities and whose height does not exceed 1 km. The dispersion, in general terms, has been directed to the western sector; the activity continued with the emission of a plume of gas and steam.
At 23 h 27, a third, moderate explosion, projected incandescent fragments on the east flank of the volcano over a distance of about 1500 m. The column of ash generated reached a height of 1 km above the crater, moving later to the west.
Similarly, 70 minutes of low-level tremor were recorded.
The volcanic alert remains at amarillo fase 2.

The Copahue stations in Chile recorded a volcano-tectonic earthquake associated with rock fracturing of local magnitude 3.4 and a depth of 3.4 km on July 7 at 03:03 local time, followed by five aftershocks of lower magnitude.
Volcanic technical alert level remains in Amarillo.
In the Philippines, although the Taal warning remains at level 1 - non-imminent hazardous eruption - there is a growing number of volcanic earthquakes: 21 reported on 5 July, 13 on 6 July, 19 on 7 July, and 26 on 8 July.
The temperature measured in the eastern part of the main crater lake did not move, at 34 ° C; only small changes in pH and levels are noticed. The building still shows a slight inflation.
