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.
The majestic El Misti volcano is Peru's most known and one of its most active volcanoes. It is an andesitic symmetrical stratovolcano that dominates the town of Arequipa, only 16 km to the SW, and its proximity to Peru's second largest city as well its history of explosive eruptions make it one of the world's most dangerous volcanoes.
The report of IGP showing the signals of the seismic swarm at EL Misti volcano in Peru
The volcano experienced an earthquake swarm during 14-15 January, IGP reported in its latest bulletin. An increase of approx. 25% in seismic activity overall with respect to last year's average was calculated, but IGP stresses that this activity is still low and does not suggest new activity in a near future. ...more
According to the report, a total of 418 seismic events were recorded during the first half of January, most of them during the swarm that occurred on 14-15 Jan when almost 120 quakes were registered within 17 hours. From these events, 144 were so called long-period quakes (internal fluid movements), 269 volcano-tectonic earthquakes (internal rock fracturing) and 5 short pulses of tremor (internal vibration). El Misti, which is only 17 km from the center of Arequipa city, is one of the countries major and most active volcanoes. Due to its closeness to a large city and its history of explosive eruptions, it is also one of the most dangerous volcanoes in South America, and clearly one that deserves being closely monitored.

El Misti volcano is showing signs of unrest, according to a recent article in the Peruvian press. Geologists from the Geophysical Institute of Peru (IGP) detected a higher number than usual of small earthquakes under the volcano located 17 km outside the city of Arequipa. ...more
The current seismic swarm the strongest in more than 5 years. Engineer Orlando Macedo told El Comercio that 224 earthquakes were registered at El Misti during the past week. The swarm contained 143 volcano tectonic earthquakes, caused by fracturing of rocks inside the volcano due to sudden changes in pressure and temperature. Despite this recent increase in activity, which indicates that the volcano is slowly reawakening and "no longer dormant", no eruption is likely imminent. For an eruption to happen, Macedo said, El Misti would have to experience even more and continued earthquake swarms as well as volcanic tremor, signs of magma movements. [less]
