Tromen Volcanic Plateau
About Tromen Volcanic Plateau
Tromen is an Argentinian stratovolcano that is the primary structure in an elongated volcanic plateau or field that extends about 70 km from Tilhue in the S to Piujenta in the N, including the Boliviano caldera and Palao dome. The Pleistocene Volcán Cerro Negro del Tromen lies immediately north. At the SSW end of this chain is Cerro Tilhue, of Pleistocene-Holocene age. The youngest lava flows originated from flank vents and descended the N and NE sides of the andesitic-to-rhyolitic volcanic complex. Holocene vents are also located in the Cerro Michico area on the lower NE flank. Eruptions were reported in the mid-18th century and in 1822. Von Wolff (1929) attributed purported eruptions of Pomahuida in 1820, 1823, 1827, and 1828 as being from Tromen, but these are not confirmed.
