Ringkasan geologi
Acoustic T-waves from a seismic swarm, possibly associated with magmatic activity, were recorded in 1991 from a location 130 km S of the Eltanin Fracture Zone (Bulletin of the Global Volcanism Network, 1991). The source was near a seamount shallower than 1,000 m in depth near the Pacific-Antarctic Ridge.
Ringkasan Wikipedia
Ringkasan InggrisHollister Ridge is a group of seamounts in the Pacific Ocean. They lie west from the Pacific-Antarctic Ridge and form three ridges that form a line; one of the ridges rises to a depth of 100 metres (330 ft) and in the past formed an island. The seamounts are composed out of basaltic and other rocks and their ages range from about 2.5 million years ago to latest Pleistocene; an acoustic swarm recorded in the southern Pacific Ocean in 1991-1992 is considered to be the manifestation of a historical eruption of the Hollister Ridge.
