The epicenter, with a depth of 567.38 km, was initially determined to be at 17.8313 degrees south latitude and 178.662 degrees west longitude.
Initially, the institute said the quake was magnitude 6.4. But a few minutes later the institute revised its magnitude to 6.2.
In an updated bulletin, the institute said the quake, which struck at 11:06 p.m., hit at a depth of 16 kilometers, about 38 km northwest of Burgos town in Surigao del Norte.
However, in the main Burgos town, the institute said the intensity of the earthquake was only magnitude 5.
The tremor was also felt in Dinagat Island, Butuan City, Abuyog in Leyte province, Tacloban City in Southern Leyte, Camiguin Island, Cebu City in the central Philippines.
The institute said the tremor, which was tectonic in origin, is not expected to cause damage. However, it said that aftershocks are expected.
The epicenter, with a depth of 46.0 km, was initially determined to be at 32.2 degrees south latitude and 177.8 degrees west longitude.

The epicentre, with a depth of 10km, was initially determined to be at a 41.9336 degrees north latitude and 146.9481 degrees east longitude.

There were no immediate reports of casualties, and no tsunami warning was issued.
The quake, which struck at 12:23 p.m., registered a 4 on the 7-point Japanese seismic intensity scale in the northern Nemuro district and the town of Shibetsu, eastern Hokkaido, and a 3 in extensive areas of the Tokachi, Nemuro and Kushiro districts, according to the JMA.
The focus of the temblor was about 10 kilometers below the seabed off the Nemuro Peninsula.

It occurred on Jan. 26, 1700.
Unraveling the clues was similar to being a detective investigating a "not-so-ancient geological crime," U.S. Geological Survey scientist Brian Atwater said during a presentation to a full house at LCC's Health and Science lecture hall Wednesday night.
But "there's an edge to this story," he said. "It's a frightening thing. ... The effects of the tsunami are not so pretty."
That is because the next quake could come at any time, though they recur on average every 500 years or so. But the intervals are highly variable, and researchers estimate that there's a 10 percent chance the region will be hit with the next magnitude 8 or larger earthquake within the next 50 years.
Whenever it occurs, it will shake the ground for several minutes from Vancouver Island to Northern California and churn up tsunamis that swamp coastal communities. Thousands may die, and the region's highway and utility infrastructure and thousands of buildings will collapse, geologists say.
Atwater is a pioneer whose research helped determine that giant "subduction zone" earthquakes have occurred in the Pacific Northwest in the past and will do so again.
It hit in the Andes region in a sparsely populated area.
The US Geological Survey said the epicentre was at a depth of 257 kilometres (160 miles). The agency said most big quakes in South America occur at a maximum depth of 70 kilometres.
The quake hit at 0850 GMT about 27 kilometres northeast of the town of Azangaro, near the border with Bolivia.
The earthquake was recorded at a magnitude of 3.0, the British Geological Survey said
The quake occurred about 2km below the surface near Newdigate, the British Geological Survey (BGS) said.
The tremor was felt at 03:42 GMT and measured 3.1, making it the biggest earthquake of the current "swarm".
One resident of Redhill said his house was shaking for between four and five seconds.
Gatwick Airport confirmed tremors had been felt overnight in the terminals, but a spokesman said operations had not been affected.
Comment: A resident in Surrey comments that she has lived in the area for 47 years and that she had never experienced an earthquake before fracking exploration began:
And Surrey isn't the only area of the UK where fracking induced earthquakes are causing serious concern, in Blackpool the obvious correlation between fracking and earthquakes has resulted in the operations being shutdown, albeit temporarily: Fracking causes strongest quake yet at new site in UK

Comment: Some early tweets reporting on the quake:
An aftershock of M5.5 is being reported:
