Geological Summary

Moyuta is the easternmost of a chain of large stratovolcanoes extending along the volcanic front of Guatemala. Like Tecuamburro volcano, Moyuta is offset about 20 km south of the main volcanic chain and lies south of the Jalpatagua Fault, overlying the southern boundary of the Jalpatagua Graben. The 1662-m-high volcano is capped by a cluster of at least three forested, steep-sided, coalescing andesitic lava domes that from some distant perspectives give the summit a flat-topped appearance. Numerous cinder cones in various stages of erosion are located on the flanks of the complex. The age of the latest eruption of Moyuta volcano is not known, although the summit domes were considered to have been emplaced in relatively recent times (Williams et al., 1964). Small fumaroles are found on the northern and southern flanks of the volcano, and hot springs are located near Azulco at the NE base and along rivers on the SE side of Moyuta.

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

Photo Gallery

Moyuta volcano, seen here on the left-center horizon from the NW, is the easternmost of a chain of large stratovolcanoes extending across Guatemala. Its flat-topped summit is formed by a cluster of lava domes. Lava flows from the volcano interfinger with lacustrine deposits in the Jalpatagua valley, partly covered by the cloud bank below the volcano. The volcano lies south of the NW-SE-trending Jalpatagua Fault and overtops the southern margin of the Jalpatagua Graben, which lies on trend with the medial graben of El Salvador.

This view from the south shows a forested lava dome, one of a cluster of at least three steep-sided, coalescing andesitic-to-dacitic domes forming the summit of Moyuta volcano. The age of the domes is not known, but they are considered to be relatively recent features. The town of Moyuta, the outskirts of which are seen in the center of the photo, was constructed high on the volcano immediately adjacent to the summit dome complex.

Moyuta volcano rises above farmlands on the Pacific coastal plain of Guatemala. The densely forested volcano is extensively dissected and is mostly of Pliocene and Pleistocene age, but has a cluster of relatively youthful andesitic-to-dacitic lava domes at its summit. North-trending faults cut the summit area and form step-like ridges. Fumaroles, acid springs, and bicarbonate-rich hot springs are located on the northern and southern flanks of the volcano.

Moyuta is the easternmost of a chain of large stratovolcanoes extending along the volcanic front of Guatemala. The summit of the 1662-m-high volcano contains a cluster of forested lava domes. It is viewed here from a small lake to its SW at the edge of the Pacific coastal plain. The age of the latest eruption of Moyuta volcano is not known.

The large forested area at the middle right is the 1662-m-high Moyuta volcanic complex, its summit composed of a series of overlapping andesitic lava domes. The small white-colored area above and to the right of the dome complex is the city of Moyuta, which lies at an altitude of nearly 1300 m. Moyuta is the easternmost of the chain of large stratovolcanoes stretching across the Guatemalan Highlands.

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.
