Answer: Pacific Ocean
Notes: Scientists have warned that the Axial Seamount underwater volcano near the Oregon coast, USA, may erupt soon due to increased earthquakes. It lies about 300 miles off Oregon’s coast in the Pacific Ocean. Axial Seamount is a shield volcano with a large caldera at its summit. It rises to a depth of 1,400 metres below sea level. It is part of the Ocean Observatories Initiative (OOI) and houses the New Millennium Observatory (NeMO), the world’s first underwater volcanic observatory. NeMO transmits real-time volcanic data via undersea cables to Pacific City, Oregon, aiding scientific research.
