Based on a pilot observation and analyses of satellite images, the Buenos Aires VAAC reported that activity at the Palena Volcanic Group began around 1530 on 22 December. Satellite images showed an ash plume drifting SE which dissipated quickly, and diffuse ash, gas, and steam near the source. [Correction: the plume observed in satellite imagery originated from a forest fire and not from an eruption.]

Geological Summary

The Palena volcano group consists of five cinder cones oriented along a NNE trend NE of Melimoyu volcano. The youthful volcanoes, named after the middle cone, are Holocene in age (Moreno 1985, pers. comm.). An ash plume observed by pilots and on satellite imagery in December 2013 was from a forest fire.

The Global Volcanism Program is not aware of any Holocene eruptions from Palena Volcanic Group. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Palena Volcanic Group page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

MODVOLC - HIGP MODIS Thermal Alert System Using infrared satellite Moderate Resolution Imaging Spectroradiometer (MODIS) data, scientists at the Hawai'i Institute of Geophysics and Planetology, University of Hawai'i, developed an automated system called MODVOLC to map thermal hot-spots in near real time. For each MODIS image, the algorithm automatically scans each 1 km pixel within it to check for high-temperature hot-spots. When one is found the date, time, location, and intensity are recorded. MODIS looks at every square km of the Earth every 48 hours, once during the day and once during the night, and the presence of two MODIS sensors in space allows at least four hot-spot observations every two days. Each day updated global maps are compiled to display the locations of all hot spots detected in the previous 24 hours. There is a drop-down list with volcano names which allow users to 'zoom-in' and examine the distribution of hot-spots at a variety of spatial scales.
MIROVA Middle InfraRed Observation of Volcanic Activity (MIROVA) is a near real time volcanic hot-spot detection system based on the analysis of MODIS (Moderate Resolution Imaging Spectroradiometer) data. In particular, MIROVA uses the Middle InfraRed Radiation (MIR), measured over target volcanoes, in order to detect, locate and measure the heat radiation sourced from volcanic activity.
