Parasitic cone in the context of Flank eruption

Barva Volcano is an andesitic stratovolcano complex in central Costa Rica, 22 km north of San José, in Heredia Province. On the eastern side of the mountain is a lake in what was the volcanic crater, called "Laguna de Barva", and on the western side it has three hills on the top which are called "Las Tres Marías". It is located in the small agricultural community of Sacramento.

Barva has several eruptive centres at its summit and many parasitic cones on its flanks. Its three principal summits visible from the Central Valley give it the common local name of Las Tres Marías (The Three Marys).

Montagu Island is the largest of the South Sandwich Islands, located in the Scotia Sea off the coast of Antarctica. Almost entirely ice-covered with only sparse rocky outcrops, Montagu consists of a large caldera with a large parasitic cone, Mount Oceanite. Several secondary volcanic cones have formed in the caldera, including Mount Belinda.

The island is rarely visited owing to the remote location, and there is only sparse vegetation. Penguins and seabirds live along the coasts. Before an eruption in 2001, which continued for several years and formed a lava delta on the northern coast, Mount Belinda was not known to have been active during the Holocene (the past 12,000 years).

Mount Murphy (75°20′S 110°44′W / 75.333°S 110.733°W / -75.333; -110.733 (Mount Murphy)) is a snow-covered mountain with steep, rocky slopes rising to 2,634 metres (8,642 ft) in Marie Byrd Land, Antarctica.It is directly south of Bear Peninsula and is bounded by Smith Glacier, Pope Glacier, and Haynes Glacier.Volcanic activity began in the Miocene with the eruption of basaltic and trachytic lava. Volcanism on the slopes of the volcano resumed much later during the Pleistocene, with a parasitic cone having been K–Ar dated to 0.9 million years old.
