Global Volcanic Activity – New Activity for the week of 20 November – 26 November 2019
Shishaldin | Fox Islands (USA) : AVO reported that increased seismicity and higher surface temperatures at Shishaldin during 19-20 November indicated elevated eruptive activity. Seismicity abruptly dropped at 0340 on 20 November and remained low, heralding another pause in activity. Tremor and surface temperatures remained low through 23 November. Seismicity again increased during 24-25 November and small explosions were detected in local and regional infrasound stations. Strongly elevated surface temperatures were observed in multiple satellite images. A partial collapse of the summit cone sometime around 1430 on 24 November produced a pyroclastic flow that traveled as far as 3 km down the NW flank. A new lava flow on the NW flank was several hundred meters long. Seismicity decreased but remained elevated during 25-26 November. Strongly elevated surface temperatures were identified in multiple satellite images, and incandescence from the summit was occasionally visible in web camera images overnight. The Aviation colour Code remained at Orange and the Volcano Alert Level remained at Watch.
White Island | North Island (New Zealand) : GeoNet reported that gas emissions at White Island were at moderate-to-high levels during 18-25 November and tremor was at moderate levels. Gas-driven fountaining from active vents on the W side of the crater floor ejected mud a few meters in the air. The Volcanic Alert Level remained at 2 and the Aviation colour Code remained at Yellow.

New Interstellar Visitor
An interstellar object from deep in space has been spotted hurtling towards our solar system. Known as 21/Borisov experts say that the object is only the second interstellar object spotted in our solar system. The first close up of the object was captured in August by experts at the Keck observatory in Hawaii. Borisov is now set to make its close approach next month passing roughly 190 million miles away from our orbit, about twice the distance from Earth to the Sun.
The object itself has a long tail made up of ice and debris stretching a whopping 100,000 miles behind it. With the tale included this makes the Borisov vastly huge staggeringly longer than 12 earths.
Despite the extensive study and focus given to the interstellar object scientists still remain clueless as to what Borisov actually is. At the moment many scientists best guess is that it is a comet, with the hope being that studying it will open the door to answers on how comets are formed in deep space.
