Geological Summary

Cerro el Tigre is the highest, NE-most, and oldest of the cluster of coalescing basaltic to basaltic-andesite Quaternary volcanoes between the Río Lempa and San Miguel volcano. The summit crater of El Tigre has been destroyed by erosion, and the flanks of the volcano are deeply dissected. Two large NNW-trending valleys, parallel to other regional fissures, cross the volcano, which lies about 7 km SE of Tecapa volcano and a similar distance NE of Usulután volcano. Although El Tigre itself is Pleistocene in age, two young cones on its flanks were mapped as Holocene by Weber and Wiesemann (1978). Cerro Oromontique and Cerro la Manita were erupted on the western and southern flanks of El Tigre, respectively, along a NW-SE-trending fissure extending towards Tecapa volcano.

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

The dissected Pleistocene volcano El Tigre is seen here from the NW on the flanks of Tecapa volcano with the town of Santiago de María at the left center. Two Holocene cones, symmetrical Cerro Oromontique in the center of the photo and Cerro la Manita, the small peak on the right horizon, were erupted along a NW-SE-trending fissure cutting the flanks of El Tigre volcano.

Heavily forested Cerro el Tigre is the NE-most and oldest of the cluster of coalescing Quaternary volcanoes between the Río Lempa and San Miguel volcano. The Pleistocene volcano is seen here from Chinameca volcano to its east, with Usulután volcano in the shadow at the left. The low cone in the sun in front of Usulután is Cerro la Manita, a Holocene cone constructed along a NW-SE-trending fissure cutting the flanks of El Tigre.

The summit of San Miguel volcano provides a vista down an E-W-trending volcanic chain between it and San Vicente volcano, the sharp-topped peak on the right horizon. The broad El Tigre volcano appears in the center of the photo beyond the slopes of Chinameca volcano in the right foreground. At the extreme left is Usulután, and to its left the summit of Taburete volcano is hidden behind a small cloud. Behind El Tigre are the peaks of the Tecapa volcanic complex.

A westward view down the axis of a cluster of volcanoes between San Miguel and San Vicente volcanoes shows the eroded Pleistocene Cerro el Tigre volcano at the left and flat-topped Tecapa volcano to its right. San Vicente volcano can be seen in the far right distance.

An E-W-trending chain of volcanoes extends ca. 30 km across eastern El Salvador. The small light-colored dot at the left is Laguna de Alegria, a crater of the Tecapa volcanic complex. No historical eruptions are known from the eroded Usulután and El Tigre volcanoes. The 2-km-wide Laguna Seca el Pacayal caldera is a prominent feature of Chinameca volcano. San Miguel is one of El Salvador's most active volcanoes; the dark area at the lower right is a lava flow from the 1819 eruption. The city of San Miguel is at the upper right.

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.
