While White Island’s “throat-clearing” eruption (NZ) was stealing the headlines, Sabancaya Volcano in Peru was continuing its almost-daily string of stratospheric injections.
The activity at Sabancaya has been showing an increasing trend over the past days and weeks, reads volcanodiscovery.com. Explosions have been frequent (up to 5-6 per day) and have regularly produced thick ash plumes rising above 32,800 ft (9 km).
Particulates ejected above this height often penetrate the stratosphere where they linger and directly cool the planet. The Volcanic Ash Advisory Center (VAAC) Buenos Aires has confirmed at least 3 stratospheric ejections over the past 3 days alone, the largest being Dec. 8’s puff to 35,000 feet (12km).
Furthermore, INGEMMET reveals a lava dome is growing in the summit crater.
Sabancaya has been incredibly active since its latest eruptive period began on Nov 06, 2016.
The phase is ongoing but has already been confirmed as a 3 on the VEI, according to volcano.si.edu.
BACKGROUND
Stratovolcano: 5967 m / 19,577 ft
Peru: -15.78°S / -71.85°W
Current status: ERUPTING (4 out of 5)
Sabancaya volcano (meaning “tongue of fire” in the Quechua Indian language) is located in the southern Peruvian Andes and is covered with several glaciers.
Historic records of past eruptions date back to 1750, but its name appears in written accounts from 1595 AD.
Eruption list: 2016 (ongoing), 2015, 2014, 2003, 2000, 1998, 1997, 1990-95, 1988, 1986, 1784, 1750, <1595(?)

UPTICK
Seismic and Volcanic activity has been correlated to changes in our sun.
The recent global uptick in earthquakes and volcanic eruptions is likely attributed to the drop-off in solar activity, coronal holes, a waning magnetosphere, and the influx of Cosmic Rays penetrating silica-rich magma.
