Volcán Bárcena

Barcena

Cono piroclastico · Mexico · 332 m

Bárcena volcano forms the elongate island of San Benedicto, seen here from the SW in March 1955. The circular summit crater at the center and the lava delta to the right of the tuff cone formed during an eruption in 1952-53. Pleistocene lava domes are located at the far NE tip of the island. Dark-colored lava from the 1952-53 eruption can be seen in the summit crater.

Sintesi geologica

Volcán Bárcena, formed by eruptions during 1952-53, is the most prominent feature of the 4.5-km-long Isla San Benedicto, the NE-most of the Revillagigedo Islands, 350 km S of the tip of Baja California. Pleistocene trachytic lava domes form the north end of the island, with Bárcena and Montículo Cinerítico at the southern end. Montículo Cinerítico is a smaller tephra cone that preceded and was largely overtopped by Bárcena, and may also have been constructed during the past few hundred years. Growth of the 300-m-high Bárcena tephra cone beginning in August 1952 was accompanied by strong explosive eruptions and pyroclastic flows. The eruption concluded the following year with the emplacement of two small lava domes in the crater and extrusion of a coastal lava delta at the SE base of the cone.

Riassunto in inglese

The Bárcena volcano is an active but not currently erupting cinder cone type volcano that encompasses the southern end of the San Benedicto Island, Mexico. It is grouped with a chain of volcanic islands known as the Revillagigedo Islands. These islands are situated in close proximity to each other, and can be found in the Pacific Ocean. They are also considered to be part of the Trans-Mexican Volcanic Belt. Volcán Bárcena is positioned 220 miles off the south-eastern coast of the Baja California peninsula. The closest city to Barcena is Cabo San Lucas, Mexico.
