Geological Summary

Deeply dissected Volcán Tahual rises about 700 m above plains south of the town of Monjas. The summit of the 1716-m-high forested stratovolcano is cut by a broad erosional crater that extends to the base of the volcano and is narrowly breached to the NE. A Holocene pyroclastic cone near the NE base of Volcán Tahual fed a short basaltic lava flow (Williams et al., 1964). The scenic lake-filled Laguna de Hoyo lies north of the volcano. This steep-walled crater and the NE-flank cinder cone lie along faults bordering a graben that extends across the eastern base of the volcano to neighboring Retana caldera on the SE.

The Global Volcanism Program is not aware of any Holocene eruptions from Tahual. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Tahual 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.

Retana caldera, between Suchitán and Tahual volcanoes, is a prominent steep-walled caldera once filled by Laguna Retana. The lake periodically became dry and was refilled in the 19th and 20th centuries and has now been drained to provide access to rich soils on the lake floor. A canal drains the lake through a notch on its northern rim (extreme right). The caldera is seen here from its eastern rim (on the flank of Suchitán volcano). Volcán Tahual is the forested volcano behind the caldera at the right-center.

Volcán Tahual, seen here from the NE, rises about 700 m above plains south of the town of Monjas. The summit of the 1716-m-high forested stratovolcano is cut by a broad erosional crater that is narrowly breached at the NE base of the volcano (center). The volcano is deeply dissected, but a Holocene pyroclastic cone near the NE base of Volcán Tahual fed a short basaltic lava flow, which forms the lighter-green area in the sunlight at the right-hand foot of the volcano.

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.
