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.
During the past days(in particular since 6 May), activity of the volcano seems to have increased. The nightly glow from the crater has become stronger and intermittent weak ash emissions also occurred in the past days. ...more
These occasional ash plumes, brownish in color, appeared to have risen calmly from the crater (without much impulse). Hence, they were probably not driven by near-surface explosions, but rather deep-seated activity inside the conduit; their brownish color furthermore suggests that the ash came mainly from older fragmented rock instead of fresh magma, although this is difficult to judge from webcam imagery alone. INETER has not yet commented on the activity. In its last bulletin from 5 May, activity was described as "usual".
The activity of the volcano remains elevated, with little changes over the past days. Bright incandescence inside the crater and mild to moderate degassing, sometimes with light ash content, are visible at the surface. ...more
Internal micro-seismic activity continues to be at high levels according to INETER's latest report. The risk of sudden explosions from the crater remains considerable and people are advised not to approach the crater. Time-lapse video of the past 8 days' activity from the crater:
INETER and SINAPRED confirmed that a small amount of lava was erupted from a small new fissure into the crater of Telica during the night, as bright glow had suggested. A warning was issued not to approach the crater because of the risk of sudden explosions. ...more
Shortly before dawn, weak ash emissions occurred from the crater, which since then has remained relatively calm, producing only a small intermittent steam/gas plume mixed with some light ash content. [less]
Nicaragua's volcanoes remain in a particularly active state. A series of approx. 12 small explosions occurred at Telica volcano on Saturday morning, the Nicaraguan Institute of Territorial Studies INETER reported. Ash columns from the eruptions rose from 300 to 1000 meters above the crater.

Intraplate volcanism: A third tectonic setting where volcanism occurs is believed to be the result of mantle plumes and not directly related to plate boundaries. So called hot spot volcanoes fall into this category.
