Isla El Tigre is a small, 5-km-wide island located across a narrow 2-km-wide strait south of Isla Zacate Grande in the Gulf of Fonseca. The conical, 783-m-high basaltic stratovolcano is the southernmost volcano of Honduras. El Tigre is less dissected than neighboring Zacate Grande volcano on the mainland to the north and is of probable Holocene age (Carr 1992, pers. comm.). A single satellitic cone, El Vigía, overlooks the village of Amapala on the NW flank.

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.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
