The Global Volcanism Program is not aware of any Holocene eruptions from Isla el Tigre. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Isla 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 morphologically youthful Isla el Tigre is a small, 5-km-wide island located south of Isla Zacate Grande in the Gulf of Fonseca. The conical 783-m-high basaltic stratovolcano, viewed here from the NE across a narrow 2-km-wide strait from Zacate Grande, is the southernmost volcano of Honduras.

|Isla el Tigre is a small, 5-km-wide island across a narrow strait south of Isla Zacate Grande in the Gulf of Fonseca of Honduras. The conical, 783-m-high stratovolcano, seen here from the NE on Zacate Grande island, is less dissected than Zacate Grande volcano and is of probable Holocene age. A single satellitic cone (far right) overlooks the NW-flank town of Amapala, Honduras' only Pacific port. The peak in the distance beyond the right-hand flank is the volcanic island of Meangura.

|Isla el Tigre in Honduras is seen here across the Gulf of Fonseca from Punta el Chiquirín on the eastern tip of El Salvador. The morphologically youthful volcano rises 783 m above the gulf and is the southernmost in Honduras. A valley on the SW flank (right) extends to the sea and disrupts the symmetry of the volcano.

|Young volcanoes dot the surface and anchor the shores of the Gulf of Fonseca, which forms the coastline of three countries. Conchagua volcano occupies the wedge-shaped peninsula (left-center) in eastern El Salvador, while Cosigüina volcano forms the prominent peninsula across the bay in Nicaragua. Clockwise from the top are the islands of Zacate Grande and El Tigre in Honduras and Meanguera and Conchaguita in El Salvador. The mouth of the Gulf of Fonseca is about 30 km wide.

A listing of samples from the Smithsonian collections will be available soon.
|Large Eruptions of Isla el Tigre||Information about large Quaternary eruptions (VEI >= 4) is cataloged in the Large Magnitude Explosive Volcanic Eruptions (LaMEVE) database of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).|
|WOVOdat||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.|
|EarthChem||EarthChem develops and maintains databases, software, and services that support the preservation, discovery, access and analysis of geochemical data, and facilitate their integration with the broad array of other available earth science parameters. EarthChem is operated by a joint team of disciplinary scientists, data scientists, data managers and information technology developers who are part of the NSF-funded data facility Integrated Earth Data Applications (IEDA). IEDA is a collaborative effort of EarthChem and the Marine Geoscience Data System (MGDS).|
|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.|
