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.
The Volcano Adventure Guide: Excellent information and background for anyone wishing to visit active volcanoes safely and enjoyably. The book presents guidelines to visiting 42 different volcanoes around the world.
Nevados de Chillán volcano in central Chile is one of the country's most active volcanoes. It is part of the Southern Volcanic Zone of the Andean Cordillera, and is composed by 3 overlapping stratovolcanoes located on a NNW-SSE-trending line.
Fist ash emission from Nevados de Chillan on 1 April 2017 (image: Sernageomin via Culture Volcan)
The volcano continues to produce infrequent explosions, probably phreatic in nature, from time to time. After two weeks of quiet, new ash emissions occurred in two pulses from the volcano yesterday morning. ...more
The first one started from around 12:35 local time and lasted about 10 minutes. It was relatively intense and generated an ash plume that dispersed towards the SSE. A smaller emission occurred at 13:55 local time, but was much smaller. A hot spot at the crater has become visible on infrared camera images during the past days. This is probably caused by hot gasses escaping at this vent.

Ash emission at Nevados de Chillán on 7 March 2017
A series of new, moderately sized ash emissions occurred from the volcano yesterday (7 Mar 2017), showing that it remains in a restless state. ...more
The last bulletin of SERNAGEOMIN mentions that there are no significant changes in seismic activity, which remains above background and is dominated by signals reflecting internal fluid movements (gasses, water, magma); 84% of the seismicity recorded between 16 and 28 February were so-called Long-Period events. The other seismic signals included volcano-tectonic quakes (pressurization causing rock fracturing), weak volcanic tremor pulses and so-called "tornillos" (6.8%), thought to reflect resonance phenomena of the volcanic conduits caused by fluid circulation.
