Nevado del Ruiz, a deadly stratovolcano in central Colombia, roared back into life Tues, April 16. The Volcanic Ash Advisory Center (VAAC) Washington warned of an ash plume reaching 19,000 ft (5800 m), or flight level 190.
The volcano has an eruptive history peppered with confirmed VEI 2 and 3 eruptions.
Though none come close to the death and destruction caused by the VEI 3 beginning in 1985:
That eruption melted a portion of a glacier sitting atop the mountain which resulted in a rampaging lahar (mud flow) rolling into nearby towns and villages, ultimately killing 25,000 — most residing in the town of Armero.
The event marked one of the worst volcanic disasters in history.
Even sadder is the fact that this tragedy could have been easily avoided if the clear warnings issued by volcanologists had been taken seriously.

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 increase in Galactic Cosmic Rays penetrating silica-rich magma.
