Aviation Color Code Red, ash emissions intensifying at Etna volcano, Italy

Ash emissions at Italy's Etna volcano are intensifying on October 1, 2019, INGV reports. The Aviation Color Code has been raised to Red.

Images of the surveillance cameras are showing and intensification of the ash emission since 08:50 UTC on October 1.

The volcanic tremor amplitude does not show significant variations compared to the previous days.

The photos below show the explosive activity at the Northeast Crater and at the Voragine crater on the afternoon of September 30 from airplane and at daybreak on October 1 from Tremestieri Etneo, on the south flank of the volcano.

Geological summary

Mount Etna, towering above Catania, Sicily's second-largest city, has one of the world's longest documented records of historical volcanism, dating back to 1500 BCE. Historical lava flows of basaltic composition cover much of the surface of this massive volcano, whose edifice is the highest and most voluminous in Italy.

The Mongibello stratovolcano, truncated by several small calderas, was constructed during the late Pleistocene and Holocene over an older shield volcano. The most prominent morphological feature of Etna is the Valle del Bove, a 5 x 10 km (5.1 x 6.2 miles) horseshoe-shaped caldera open to the east.

Two styles of eruptive activity typically occur at Etna. Persistent explosive eruptions, sometimes with minor lava emissions, take place from one or more of the three prominent summit craters, the Central Crater, NE Crater, and SE Crater (the latter formed in 1978). Flank vents, typically with higher effusion rates, are less frequently active and originate from fissures that open progressively downward from near the summit (usually accompanied by strombolian eruptions at the upper end).

Cinder cones are commonly constructed over the vents of lower-flank lava flows. Lava flows extend to the foot of the volcano on all sides and have reached the sea over a broad area on the SE flank. (GVP)

I have stated repeatedly since 2013 that many volcanoes including Yellowstone Super-volcano will erupt between 2019-2020. Soon you will find out why Jamal Shrair is the Supreme God of physics

Jamal, you're brilliant, and honest, but don't you think that most, if not all scientist, that is 'real scientist' already know that earths poles are shifting? I think they do because no scientist surely could be that stupid. Questions is, why are they pretending otherwise?

hhehehe in this case i know at least 50 god of physics and i am one of them . Yellowstone at least for the moment . No signs of major erruption... north pole has 300 miles till 40 degree mark .i think then major shift will take place. within next 5 years if we are lucky . let see :) best are on the table
