Strong ash emissions from the volcano were reported by a pilot shortly after midnight (UTC). The reported height of the plume was to up to 70,000 ft (21 km) altitude, which would indicate an unexpected, and sudden major explosion took place (if the observed plume was volcanic ash and not something else). Anchorage VAAC raised the Aviation Color Code to RED.read all

Volcano Calendar 2018: We're proud to present our 2018 volcano calendar: 13 different and attractive images of volcanoes, volcanic landscapes and phenomena taken during volcano tours over the past few years.
Dallol hot springs: One of the most bizarre landscapes on earth: Dallol is a vast and very active hydrothermal field creating a colorful array of hot springs, small geysers, salt towers, colorful lakes and ponds in the middle of the deepest part of the Danakil desert and the Karum salt lake.
Climbing Stromboli volcano: Stromboli provides one of the most remarkable opportunities to watch volcanic eruptions from close: a natural ridge located 150 m above the active vents. A classic and all-time favorite tour by anyone interested in seeing active volcanoes!
