Geological Summary

A chain of dominantly basaltic cinder cones erupted along two NE-SW-trending fissures at the head of Puyuhuapi fjord comprise the Volcanes de Puyuhuapi. The larger group of four cones lies on the western side of Puyuhuapi fjord and fed lava flows that traveled SE to the sea. The second lineament formed a chain of four smaller cones between the head of the fjord and Lake Risopatrón to the north. The two fractures are related to the regional Liquiñe-Ofqui fault zone. The Puyuhuapi cinder cones are extremely well preserved, suggesting a very young age.

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

A chain of cinder cones was erupted along NE-SW-trending fissures at the head of Puyuhuapi fjord (top-center) in this NASA International Space Station image (with north to the upper left). The Volcanes de Puyuhuapi consists of a larger group of four cones on the western side of Puyuhuapi fjord and a chain of smaller cones north of the head of the fjord. The two fractures and the fjord are related to the regional Liquiñe-Ofqui fault zone. The town of Puyuhuapi lies on the western side of the fjord, about halfway down its visible length in this image.

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.
