Photo Gallery

Magaso, also known as Cuernos de Negros, is a large stratovolcano that anchors the SE tip of Negros Island. The volcano is located just right of center in the cloud-covered portion of SE Negros Island in this Space Shuttle image (with north to the upper right), directly across the channel and in line with the SW tip of Cebu Island at the right side of the image. No historical eruptions are known from Magaso, but the summit crater is fumarolically active, and the Palinpinon geothermal field are located at its base.

The broad Cuernos de Negros volcanic complex is seen here from the small island of Apo, 7 km SE of the city of Zamboanguita at the southern end of Negros Island. The eastern side of the complex consists of two cones and a lava dome with two crater lakes up to 1.5 km in diameter. The small summit crater of Magaso, the highest peak of the complex, rises above the city of Dumaguete and contains fumaroles. The Palinpinon geothermal field is located on the north side of the volcano.

Cuernos de Negros is a large volcano composed of multiple edifices including Mount Talines, Mount Guinsayawan, and Guintabon Dome, seen in this June 2017 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 24 km across). The Magaso summit crater contains active fumaroles and the Palinpinon geothermal field is on a N flank.
