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.
Telica, one of the most active volcanoes in Nicaragua, is a group of overlapping cones and craters on a broad NW line. The most prominent vent is a 700 m wide and 120 m deep double crater at the summit. Its southern summit crater has been the source of Telica's recent eruptions.
The older Santa Clara vent at the SW end of the edifice erupted in 16th century and is now covered with vegetation. Another vent El Liston, immediately SE of Telica, is another volcanic edifice with several nested craters.
Fumaroles and boiling mudpots are found at Hervideros de San Jacinto, SE of Telica. This prominent geothermal area is popular among tourists and the site of nearby geothermal exploration.
Telica volcano (Nicaragua): new explosion, 3km ash plume

Telica's eruption seen by the INETER webcam
After a week of calm, a new phase of explosive activity occurred yesterday at the volcano, beginning with a moderately large explosion at 12:02 local time. An ash plume rose approx. 3 km above the summit:
Several smaller explosions and phases of calm ash venting followed this event. Ash falls were noted in up to 15 km distance to the SW, in areas of the villages Posolega and Quezalguaque.
So far it is unclear whether the explosions are the result of phreatic or hydrothermal activity, i.e. caused by pressurized fluids in the shallow hydrothermal system, or whether they are result of new magma reaching the surface.
For now, INETER has not found evidence of fresh magmatic material in the deposits of the explosions - all ash and blocks are fragmented older rocks from near the surface - and the accompanying seismicity has been very shallow. This would favor the first scenario.
Seismic activity with frequent volcanic-tectonic quakes remains above background. A series of small earthquakes with magnitudes up to about 2 has been occurring recently directly under the volcano.
Colima volcano photos: This beautiful stratovolcano in western Mexico is one of the most active volcanoes on the American continents. It is known for its often spectacular explosions and sometimes glowing avalanches.
