Farallón de Pájaros

Farallon de Pajaros

Estratovolcán · United States · 337 m

The 2-km-wide island of Farallon de Pajaros is the northernmost and most active volcano of the Mariana Islands. It has been referred to as the "Lighthouse of the western Pacific." The symmetrical, sparsely vegetated cone formed within a caldera, remnants of which form the peak seen here in 1980 in the center along the SE coast. Both summit and flank vents have been active during historical time; flank fissures formed lava flows along the coast.

Resumen geológico

The small 2-km-wide island of Farallon de Pajaros (also known as Uracas) is the northernmost and most active volcano of the Mariana Islands. Its relatively frequent eruptions dating back to the mid-19th century have caused the andesitic volcano to be referred to as the "Lighthouse of the western Pacific." The symmetrical, sparsely vegetated summit is the central cone within a small caldera cutting an older edifice, remnants of which are seen on the SE and southern sides near the coast. Flank fissures have fed lava flows that form platforms along the coast. Eruptions have been recorded from both summit and flank vents.
