The United States Geological Survey says an undersea volcano near Farallon de Pajaros in the Northern Marianas can erupt any time.
The agency’s Hawaiian Volcano Observatory has been keeping a close eye on the undersea volcano that has been showing signs of activity in recent days.
According to a weekly summary issued by the Observatory, recent seismic activity almost certainly herald an eruption.
According to the USGS report, seismometers on the islands recorded high levels of seismicity and the most likely source of the volcanic activity is the Ahyi seamount, which is about 20 kilometres southeast of Farallon de Pajaros.
The seamount rises to within 64 metres of the ocean surface and is associated with several reports of possible eruptions in historical times, the most recent in 2001.

Authorities say a Florida-bound plane returned to Philadelphia after encountering severe turbulence that injured six people.
The Philadelphia Inquirer reports that the turbulence encountered Sunday by the Orlando-bound US Airways flight lasted only a few seconds, but four passengers and two flight attendants reported injuries.
The pilot then turned the plane back to Philadelphia. The airline says five people were taken to hospitals and their conditions weren’t known, but none of the injuries appeared life-threatening.
US Airways spokesman Bill McGlashen says the seatbelt sign was still on at the time of the turbulence, which occurred when the plane was at 17,000 feet.
Airport spokeswoman Stacy Jackson says another plane took off at 8 p.m. Sunday to carry the passengers to Orlando.
