Photo Gallery

Explosive activity was frequently observed from Farallon de Pajoras volcano in October and November 1952. Lava flows were emplaced on the E and W sides of the summit in February-March 1953. This 1953 photo from the E shows a small plume rising above the summit crater and lighter-gray lava flows in the center that erupted in 1953. The lobe just left of center eventually reached the coast. Explosive activity continued until 15 April. The steep-sided peak on the SE coastline is a remnant of an older caldera.

Photo by U.S. Navy, 1953.
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.

Photo by Winfrey, 1980 (U.S. Navy).
This 1980 photo from the SE of the small island volcano of Farallón de Pájaros shows unvegetated lava flows that diverted around the vegetated peak to the lower right, which is a remant of a caldera that formed prior to the formation of the present cone.

Photo by Winfrey, 1980 (U.S. Navy).
Ahyi seamount (upper right) is a large submarine volcano that rises to within about 150 m of the sea surface about 18 km SE of the island of Farallon de Pajaros (left-center). At various times since 1979, water discoloration, felt seismicity followed by upwelling of sulfur-bearing water, and a seismically detected submarine eruption have been reported at or near the seamount. Two submarine volcanoes on the flanks of Farallon de Pajaros, Northwest Uracas and Makhahnas, are seen in this NOAA bathymetric image.
