The Global Volcanism Program is not aware of any Holocene eruptions from Isla del Tigre. If this volcano has had large eruptions (VEI >= 4) prior to 12,000 years ago, information might be found on the Isla del Tigre page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).
There is no Deformation History data available for Isla del Tigre.
There is no Emissions History data available for Isla del Tigre.
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.
Isla el Tigre stratovolcano forms a small island in the Gulf of Fonseca across a narrow strait from Isla Zacate Grande (upper right), a volcano forming a peninsula on the Honduras mainland. A single satellitic cone lies immediately south of the town of San Pablo on the NNW side of the 5-km-wide island (upper left).
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.
The 5.5-km-wide Isla del Tigre is located in the Gulf of Fonseca in Honduras, shown in this October 2019 Planet Labs satellite image monthly mosaic (N is at the top). There is a crater just below the summit on the southern flank as well as several other flank craters including El Vigía on the NW flank, just NE of the lake near the shore.Maps are not currently available due to technical issues.
There are no samples for Isla del Tigre in the Smithsonian's NMNH Department of Mineral Sciences Rock and Ore collection.
| Copernicus Browser | 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. |

Users can customize a variety of filters and options in the left panel. Note that if there are no stations are known the map will default to show the entire world with a "No data matched request" error notice. |

Users can customize the data search based on station or network names, location, and time window. Requires Adobe Flash Player. |
| 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. |
| Large Eruptions of Isla del 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). |
| 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). |
