The US Geological Survey reported two quakes, one of 7.1 magnitude and one of 7.0 magnitude.
In Japan, authorities said a one-metre (three-foot) tsunami could be headed toward the Philippines, while the US Pacific Tsunami Warning Centre (PTWC) cautioned nations in the region to be on alert.
"Earthquakes of this size sometimes generate local tsunamis that can be destructive along coasts located within 100 kilometres (60 miles) of the earthquake epicentre," the PTWC said on its website.
"Authorities in the region of the epicentre should be aware of this possibility and take appropriate action," it said.
The Japanese Meteorological Agency said the quake was "able to trigger" a one-metre high tsunami that would be on course to hit Basco in the northern Philippines.
"But since it's been nearly two hours since the quake without any tsunami being observed, the possibility is declining," an agency official said.
After Tuesday's alert, there was some immediate confusion about the strength and danger to the region.
