Geological Summary

The summit of the andesitic-to-basaltic Volcán Suchitán stratovolcano, NE of the city of Jutiapa, is elongated N-S. Several large canyons cut the slopes of the dominantly andesitic edifice. A large cone, Cerro Mataltepe, is located on the upper N flank; two smaller cones are located on the lower N flank. Two Holocene basaltic lava flows are also present on the N and NW flanks (Williams et al., 1964), and many flank vents are basaltic. The volcano was constructed immediately E of the 5-km-wide basaltic-to-dacitic Retana caldera, formed in part in association with the eruption of a dacitic pumice deposit. Steep walls 60-250 m high rise above the flat caldera floor. One of the latest basaltic lava flows went through a low notch in the eastern caldera rim. Several lava cones and a maar are located along a N-S line N of Retana caldera. A reported eruption in 1469 CE is considered to have actually been from Atitlán volcano in the Guatemalan highlands.

Photo Gallery

Suchitán volcano, seen here from the west on the rim of Retana caldera, is the highest of a group of closely spaced small volcanoes including scoria cones in SE Guatemala. The large peak to the left of the summit is Cerro Mataltepe; other scoria cones occur lower on the north flank. One of the more recent lava flows from Suchitán traveled through a low notch in the eastern caldera rim. The caldera once contained a lake, but now is used for agricultural land.

The floor of the 5-km-wide Retana caldera between Suchitán and Tahual volcanoes is now used for farmland. The caldera walls range up to 250 m in height, with a low notch on the northern rim (left).

Retana caldera, between Suchitán and Tahual volcanoes, was 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 access the rich soils on the lake floor. A canal drains the lake through a notch on its northern rim (far right). The caldera is seen here from its eastern rim, on the flank of Suchitán. Volcán Tahual is the forested volcano just behind the caldera wall and to the right.

This view from the Apaneca Range shows the CH-A well and drill rig of the Ahuachapán geothermal field in the foreground. The peak on the left horizon across the lowlands of El Salvador's interior valley is Volcán Chingo, along the El Salvador/Guatemala border. The flatter peak to the far right is Volcán Suchitán in Guatemala.

The irregular summit ridge of Volcán Suchitán is seen here from the SSW, west of the city of Asunción Mita. The edifice is extensively eroded, and large gullies descent its slopes. Two lava flows of estimated Holocene age were erupted from vents on the N and NW flanks.

The northern wall of Coatepeque caldera rises about 250 m above the surface of Lago de Coatepeque, whose shores are lined with residences and small hotels. The peak beyond the caldera to the left is Volcán Chingo along the El Salvador/Guatemala border. The broader peak to the far right is Volcán Suchitán, one of the largest volcanoes in SE Guatemala.

The Copernicus Browser replaced the Sentinel Hub Playground browser in 2023, to provide access to Earth observation archives from the Copernicus Data Space Ecosystem, the main distribution platform for data from the EU Copernicus missions.

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.

MODVOLC Thermal Alerts

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.

WOVOdat
   Single Volcano View
   Temporal Evolution of Unrest
   Side by Side Volcanoes

WOVOdat is a database of volcanic unrest; instrumentally and visually recorded changes in seismicity, ground deformation, gas emission, and other parameters from their normal baselines. It is sponsored by the World Organization of Volcano Observatories (WOVO) and presently hosted at the Earth Observatory of Singapore.

GVMID Data on Volcano Monitoring Infrastructure The Global Volcano Monitoring Infrastructure Database GVMID, is aimed at documenting and improving capabilities of volcano monitoring from the ground and space. GVMID should provide a snapshot and baseline view of the techniques and instrumentation that are in place at various volcanoes, which can be use by volcano observatories as reference to setup new monitoring system or improving networks at a specific volcano. These data will allow identification of what monitoring gaps exist, which can be then targeted by remote sensing infrastructure and future instrument deployments.

Volcanic Hazard Maps

The IAVCEI Commission on Volcanic Hazards and Risk has a Volcanic Hazard Maps database designed to serve as a resource for hazard mappers (or other interested parties) to explore how common issues in hazard map development have been addressed at different volcanoes, in different countries, for different hazards, and for different intended audiences. In addition to the comprehensive, searchable Volcanic Hazard Maps Database, this website contains information about diversity of volcanic hazard maps, illustrated using examples from the database. This site is for educational purposes related to volcanic hazard maps. Hazard maps found on this website should not be used for emergency purposes. For the most recent, official hazard map for a particular volcano, please seek out the proper institutional authorities on the matter.

DECADE Data

The DECADE portal, still in the developmental stage, serves as an example of the proposed interoperability between The Smithsonian Institution's Global Volcanism Program, the Mapping Gas Emissions (MaGa) Database, and the EarthChem Geochemical Portal. The Deep Earth Carbon Degassing (DECADE) initiative seeks to use new and established technologies to determine accurate global fluxes of volcanic CO₂ to the atmosphere, but installing CO₂ monitoring networks on 20 of the world's 150 most actively degassing volcanoes. The group uses related laboratory-based studies (direct gas sampling and analysis, melt inclusions) to provide new data for direct degassing of deep earth carbon to the atmosphere.
