成層火山 · El Salvador · 1640m

The eroded Pleistocene El Tigre volcano is seen here from the flank of Tecapa to the NW with the town of Santiago de María near the center. Two Holocene cones are seen here, Cerro Oromontique right of Santiago de María and Cerro la Manita, the small peak on the horizon to the right. · 写真: Photo by Kristal Dorion, 1994 (U.S. Geological Survey). · Wikimedia Commons

地質学的概要

Cerro el Tigre is the highest, NE-most, and oldest of the cluster of coalescing basaltic to basaltic andesite Quaternary volcanoes between the Río Lempa and San Miguel volcano. Its summit crater has been destroyed by erosion, and its flanks are deeply dissected. Two large NNW-trending valleys, parallel to other regional fissures, cross the volcano, which lies about 7 km SE of Tecapa volcano and a similar distance NE of Usulután volcano. Although the volcano itself is Pleistocene in age, two young cones on its flanks were mapped as Holocene by Weber and Wiesemann (1978). Cerro Oromontique and Cerro la Manita were erupted on the W and S flanks, respectively, along a NW-SE-trending fissure extending towards Tecapa.
