volcano
Mexico's Popocatépetl continued its eruptive uptick in style at 15:40 UTC on June 14, with a strong Vulcanian-Type Explosion — one of the volcano's largest eruptions in years.

The Volcanic Ash Advisory Center (VAAC) Washington has warned of a thick ash column rising to at least 32,000 feet (9.8 km) a.s.l. and moving in a NE direction at 30-35 kts .

Particulates ejected to altitudes above 32,800 feet (10km) or FL328 —and into the stratosphere— have a direct cooling effect on the planet.

Twitter was quickly clogged with awesome photos and footage:





Popocatépetl, whose name means Smoking Mountain in Nahuatl, the language of the Aztecs, sprang back to life in 1994 (solar minimum of cycle 22) after half a century of quiescence.

Over the past few months, violent activity at the volcano has increased tenfold, correlating neatly with the sharp drop-off in solar activity (see 'UPTICK' below).

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.
