San Félix Island, 800 km W of the Chilean coast, consists largely of a low, cliff-bounded lava platform separating two tuff cones. The Islota Gonzáles cone to the SW is separated from the main island by a shallow submerged platform. Cerro Amarillo at the western end forms the high point of the island and is the source of fresh-looking hawaiite lava flows that reached the sea and formed the low lava platform at the SW tip of the island. A ship captain reported a dull red glow at the summit in 1923. Willis and Washington (1924) considered the youthful lava flows to predate discovery of the island in the 16th century, but not be more than a few centuries old. However, Ar-Ar dating by Haase et al. (2000) determined that the adjacent plateau age was 421 +/- 18 ka, and considered the advanced erosion of the island as indicative of several hundred thousands of years of inactivity.
The Global Volcanism Program is not aware of any Holocene eruptions from San Felix. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the San Felix 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.
|Feature Name||Feature Type||Elevation||Latitude||Longitude|
|Amarillo, Cerro||Tuff cone||193 m||26° 16' 0" S||80° 7' 0" W|
|Gonzales, Islota||Tuff cone||132 m||26° 40' 0" N||80° 7' 0" W|
The Global Volcanism Program has no photographs available for San Felix.
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.
