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.
Popocatepetl is one of Mexico's most active volcanoes. After almost 50 years of dormancy, "Popo" came back to life in 1994 and has since then been producing powerful explosions at irregular intervals.
In the past centuries befor European invasions, large eruptions produced giant mud flows that have buried Atzteque settlements, even entire pyramids.
The activity at the volcano remains comparably elevated as the following summary from the Smithsonian / USGS Weekly Volcanic Activity Report 22-28 November 2017 shows: ...more
"Each day during 22-28 November CENAPRED reported 188-725 emissions and as many as five explosions. Two explosions on 23 November produced minor ashfall in the municipalities of Huaquechula (30 km SSW), Tepeojuma (39 km SE), Atlixco (23 km SE), and Izúcar de Matamoros (50 km SSE), in the state of Puebla.

Volcán Popocatépetl, whose name is the Aztec word for smoking mountain, towers to 5426 m 70 km SE of Mexico City to form North America's 2nd-highest volcano. The glacier-clad stratovolcano contains a steep-walled, 250-450 m deep crater. The generally symmetrical volcano is modified by the sharp-peaked Ventorrillo on the NW, a remnant of an earlier volcano. At least three previous major cones were destroyed by gravitational failure during the Pleistocene, producing massive debris-avalanche deposits covering broad areas south of the volcano. The modern volcano was constructed to the south of the late-Pleistocene to Holocene El Fraile cone. Three major plinian eruptions, the most recent of which took place about 800 AD, have occurred from Popocatépetl since the mid Holocene, accompanied by pyroclastic flows and voluminous lahars that swept basins below the volcano. Frequent historical eruptions, first recorded in Aztec codices, have occurred since precolumbian time.
Ubinas activity updates: The most frequently active volcano in Peru entered a new eruptive phase in 2014. Updates and news are regularly posted on this page.
