Roundup of Global Volcanic Activity
Nevado del Ruiz (Colombia): The volcano produced again several small to moderately-sized ash eruptions during yesterday and today, generating plumes that rose up to approx. 1 km above the crater. The most significant emissions occurred occurred yesterday morning at 08:22 and today at 07:48 local time and were accompanied by a strong tremor signals.
Dallol (Danakil desert, Ethiopia): Help us protect Dallol and have it listed as UNESCO World Heritage Site by contributing to an ambitious and very interesting crowd-sourced project: Dallol is located in the northern Danakil desert of Ethiopia, at the bottom of the African rift. It is a salt dome with a unique and bizarre array of colorful geysers, hot springs, acid lakes and mineral pools encrusted with sulphur and various salt crystals. It is not a volcano in the strict sense, but a very active hydrothermal area that results from the interaction between the salt water from the Red Sea, evaporation deposits and heat from an underlying magma chamber, hidden beneath more than 2 km of salt. This geological and biological heritage is now threatened by a large-scale mining industry plans. World-renowned photographer and director Olivier Grunewald is working on a documentary in order to raise awareness among the Ethiopian authorities and beyond, to urge them to apply for its nomination as a UNESCO World Heritage Site.
