A huge 7.8 magnitude earthquake has struck off the coast of Fiji in the Ring of Fire region.

It hit 123 km east south east of Suva, Fiji, at a depth of 669 km, the U.S. Geological Survey said today.

The Pacific Tsunami Warning Center said no destructive Pacific-wide tsunami was expected, and there was no tsunami threat to Hawaii.

It has been downgraded from an initial reading of 8.1 by the US Geological Survey.

Fiji sits on the Pacific 'Ring of Fire' where many of the world's earthquakes and volcanic eruptions are recorded.

New Zealand's Ministry of Civil Defence and Emergency Management said there was no tsunami threat to New Zealand following the earthquake. </s> A powerful earthquake with a preliminary magnitude of 7.8 has struck just off the coast of Fiji, but it was centered far below the seabed, seismologists say. There is no threat of a tsunami.

The earthquake, which struck at 3:49 a.m. local time on Friday, was centered about 41 kilometers (25 miles) southeast of Levuka on Fiji’s Ovalau island. It struck at a depth of 669 kilometers (415 miles).

The U.S. Geological Survey (USGS) put the preliminary magnitude at 7.8, which is down from an initial estimate of 8.1. It makes it the world’s third largest earthquake so far this year.

“Based on all available data, there is no tsunami threat because the earthquake is located too deep inside the Earth,” the Pacific Tsunami Warning Center said in a bulletin. No tsunami warnings were issued.

The depth of the earthquake significantly reduced its impact. USGS computer models estimate that up to 924,000 people near the epicenter may have felt “weak” or “light” shaking. Serious damage is unlikely.

Friday’s tremor comes less than three weeks after an 8.2-magnitude earthquake struck far below the seabed near Fiji. That earthquake was further away from land but there were no reports of serious damage.

Fiji is on the Pacific Ring of Fire, an arc of fault lines circling the Pacific Basin which is prone to frequent and large earthquakes. </s> The Pacific Tsunami Warning Center said there is no tsunami threat to Hawaii following a 8.2 magnitude earthquake this afternoon near Fiji.

The Pacific Tsunami Warning Center said there is no tsunami threat to Hawaii following a 8.2 magnitude earthquake this afternoon near Fiji.

The U.S. Geological Survey said the quake hit at a depth of 348 miles and was located 174 miles northeast of Fiji’s Ndoi Island. No casualties are expected based on initial readings.

Small tsunami waves have been observed but the Pacific Tsunami Warning Center said a destructive Pacific-wide tsunami is not expected based on available data. </s> A massive quake of magnitude 8.2 struck in the Pacific Ocean close to Fiji and Tonga on Sunday but it was so deep that it was not expected to cause any damage, the U.S. Geological Survey (USGS) said.

The U.S. Tsunami Warning Center also said the quake was too deep to cause a tsunami.

The quake was 347.7 miles (560 km) below the Earth which would have dampened the shaking at the surface.

'I would not expect any damage. People will feel it but it's so deep that I would not expect any damage,' USGS geophysicist Jana Pursley said by telephone.

The quake was initially reported as a magnitude 8.0 and then upgraded to 8.2, a magnitude that could cause tremendous damage had it not been so deep.

The epicenter was located 167 miles (270 km) east of Levuka in Fiji and 275 miles (443 km) west of Neiafu in Tonga.

The area is located on the earthquake-prone Ring of Fire. </s> An magnitude 7.8 earthquake has struck off the cost of Fiji.

It hit 123km south east of Suva at a depth of 669 km, the US Geological Survey has said.

The Pacific Tsunami Warning Center said no destructive Pacific-wide tsunami was expected, and there was no tsunami threat to Hawaii.

New Zealand's Ministry of Civil Defence and Emergency Management said there was also no tsunami threat to New Zealand.

The measure was revised from an initial magnitude 8.1 reading by USGS.

According to reports, the earthquake struck at 3.49 am local time.

Fiji and Tonga have been impacted by the tremors, Fox KTVU reports.

Suva is said to be the main cultural and tourist centre of the Fiji Islands. </s> A powerful magnitude 7.9 quake has struck in the Pacific Ocean, 291 km (180 miles) from Ndoi island of Fiji, according to the United States Geological Survey (USGS). The quake hit at a depth of 570km (354 miles), too deep to cause a tsunami. Its power approaches the strongest deep-focus (over 300km deep) quake on record, the magnitude 8.3 Okhotsk Sea quake of 2013.From HawaiiNewsNow There is no tsunami threat to Hawaii after a strong earthquake in the South Pacific basin.Officials at the National Tsunami Warning Center said the quake struck the Fiji Islands region Saturday afternoon, but no Pacific-wide tsunami threat was generated.It initially registered as a 7.9-magnitude earthquake, but since the original alert, the USGS has upgraded the magnitude of the earthquake to an 8.2. </s> (Reuters) - A magnitude 8.1 earthquake hit 123 km east south east of Suva, Fiji, at a depth of 669 km, the U.S. Geological Survey said on Thursday.

The Pacific Tsunami Warning Center said no destructive Pacific-wide tsunami was expected, and there was no tsunami threat to Hawaii. </s> A magnitude 7.8 earthquake hit 105 km east-southeast of Suva, Fiji, at a depth of 608 km, the U.S. Geological Survey said on Thursday.

The measure was revised downward from an initial magnitude 8.1 reading by USGS.

The Pacific Tsunami Warning Center said no destructive Pacific-wide tsunami was expected, and there was no tsunami threat to Hawaii.

New Zealand’s Ministry of Civil Defence and Emergency Management said there was no tsunami threat to New Zealand following the earthquake. </s> FIJI - Shortly after 8 p.m. our time Saturday, a massive earthquake was reported near Fiji in the south Pacific Ocean. It was an 8.2 magnitude earthquake that happened in the deep ocean.

Preliminary reports suggest that there is no tsunami threat to Hawaii. Given the depth of this quake, the tsunami threat is considered low elsewhere too.

If this quake were to happen on land and at a shallower depth, the damage would be major.

As of 9:30 p.m. our time Saturday, we have not heard any reports of damage in Fiji. This is a developing story.
A magnitude 7.8 earthquake occurs off the coast of Fiji. The Pacific Tsunami Warning Center says no tsunami is expected due to its depth.
