<P> Sabancaya is an active 5,976 - metre (19,606 ft) stratovolcano in the Andes of southern Peru, about 100 kilometres (62 mi) northwest of Arequipa . It is the most active volcano in Peru, with an ongoing eruption that started in August 2014 . </P> <P> Ubinas is another active volcano 5,672 - metre (18,609 ft) in southern Peru with an ongoing eruption . Until 2006, this stratovolcano had not erupted for about 40 years . On April 23, 2006, Peru declared a state of emergency in towns near the volcano . On April 28, 2014, despite a recent decline in earthquakes, Ubinas Volcano erupted an ash plume on April 28, 2014 . </P> <P> The Volcanological and Seismological Observatory of Costa Rica (OVSICORI) at the National University of Costa Rica, in Spanish Observatorio Vulcanológico y Sismológico de Costa Rica (OVSICORI) have a dedicated team in charge of researching and monitoring the volcanoes, earthquakes, and other tectonic processes in the Central America Volcanic Arc . In 1984, the OVSICORI - A initiated the operation of a seismographic network designed to monitor seismic and volcanic activity throughout the national territory . Currently, the seismographic network has an analog and a digital registration system . The latter enables online analysis of seismic signals, allowing to expedite the analysis of signals and the study using modern computerized methods . Poás Volcano is an active 2,708 - metre (8,885 ft) stratovolcano located in central Costa Rica; it has erupted 39 times since 1828 . On February 25, 2014, a webcam from the OVSICORI captured the moment a dark cloud exploded about 1,000 feet (300 m) in the air from a massive crater of the Poás Volcano . </P> <P> In 1902, the Santa Maria Volcano erupted violently in Guatemala, with the largest explosions occurring over two days, ejecting an estimated 5.5 km (1.3 mi) of magma . The eruption was one of the largest of the 20th century, only slightly less in magnitude to that of Mount Pinatubo in 1991 . The eruption had a volcanic explosivity index of 6 . Today Santiaguito is one of the world's most active volcanoes. (1) (2) </P>
