The US Geological Survey has upgraded the powerful quake off Russia to magnitiude 8.7 quake, which occured 133km south east of Petropavlovsk-Kamchatsky.
The Pacific Tsunami Warning Center has issued a tsunami watch for Guam and the Northern Mariana Islands.
The Center says the potential tsunami impact is still being evaluated (as of 11:35am NZT).
It says if a threat exists, the earliest arrival for Guam, Rota, Saipan or Tinian would be 2.37pm Chamorro Standard Time (5:37pm NZT).
It says a threat to American Samoa from this earthquake is still under investigation.
The US Geological Survey said hazardous tsunami waves were possible within next three hours along some coasts of Russia and Japan.
The Tsunami Warning centres says tsunami waves reaching more than three metres about the tide level are possible along some coasts:
The tsuami waves reaching one to three meters above the tide level are possible along some coasts of Chile, Hawaii, Japan and Nothern Hawaiian islands, and Solomon Islands.
The Tsunami Warning Centre says tsunami waves reaching 0.3 to one metre above the tide level are possible for some coasts of:
A tsunami warning has been issued for the state of Hawai'i effective at 2:43pm local time.
It says a tsunami has been generated that could cause damage along coastlines of all islands in Hawai'i.
Urgent action should be taken to protect lives and property.
The estimated arrival time in Hawaii of the first tsunami wave is 7:17pm local time 29 July (5:17pm NZT, 30 July)
The Tsuami Warning Centre says based on all available data there is a threat to Guam, Rota, Tinian and Saipan.
It says sea level fluctuations and strong ocean currents that could be a hazard along beaches in harbors and in coastal waters.
It says the earliest estimated time that hazardous sea level fluctuations and strong ocean currents may begin in Guam, Rota, Tiniana and Saipan is 2:37pm local time (5:27pm NZT).
It says recommended actions include:

Tsunami Advisories Lifted Across Pacific Following Magnitude 8.8 Quake Off Russia's Coast
Article – RNZ There are now no formal warnings in the Pacific, but the threat of tsunami waves remains possible. RNZ Pacific Most formal tsunami warnings and advisories have been lifted in the Pacific region following a magnitude 8.8 earthquake off the Russian coast. The Pacific Tsunami Warning Center says the threat of tsunami waves remains possible. Earlier, CNN reported authorities saying tsunami waves started to hit the Marquesas Islands of French Polynesia around 10,000 kilometres away from the epicenter. Emergency authorities in the Northern Marianas cancelled the tsunami advisory for Guam and the CNMI at around 7pm Wednesday local time. Scientists at the US National Weather Service in Guam say they were fortunate the peak impacts occurred close to low tide, so wave gauges showed very small fluctuation in wave height. Parts of California and Alaska remain under tsunami advisory. Authorities say French Polynesia could be hit with waves up to four metres high, Reuters reports. They have revised their the tsunami alert for the Marquesas Islands archipelago, saying waves of up to four metres could reach the islands of Ua Huka, Nuku Hiva, and Hiva Oa overnight. A previous alert said waves of up to 2.2m could affect the islands. Earlier, the French Armed Forces in French Polynesia said they were 'on alert as a precautionary measure' to assist any potential search and rescue or medical evacuation operations.

Magnitude 8.8 Quake East Of Russia
An estimated magnitude 8.8 earthquake off Russia's eastern coast has resulted in tsunami warnings across much of the Pacific. New Zealand's coasts may experience 'strong and unusual currents and unpredictable surges' and NEMA has advised staying off beaches and shore areas. The Russian city of Petropavlovsk-Kamchatsky, with a population of 180,000 people, is close to the earthquake epicentre. The SMC asked experts to comment. 'Today's earthquake that occurred just off the Kamchatka peninsula is a large magnitude event (M8.8), and occurred on a subduction zone where the Pacific Plate is diving down under the Okhotsk Plate – and because it was offshore, it generated a tsunami. 'According to the USGS, the area has a relatively small population, so damage or injuries to local people and property isn't expected to be too large. The US Pacific Northwest and Alaskan coasts are under a Tsunami Advisory, with waves of less than 1 ft expected in some northern areas, with Crescent City (a promontory on the Oregon Coast) having the largest predicted waves of up to 4.8 ft (USGS). 'At last count, there have already been 10 aftershocks above magnitude 5, the largest at M6.9. This demonstrates that large magnitude earthquakes generate aftershock sequences that start immediately, and some of these can be damaging in their own right. From the perspective of local people, their experience of this earthquake is going to be compounded in the coming weeks, months and years by on-going aftershock activity, which can have a significant psycho-social affect. 'Aotearoa lies just over 9,600 km from the epicentre, with nothing but the Pacific Ocean between us. New Zealand is no stranger to the effects of distant tsunami events, for example our experience of the 1960 M9.6 Chilean earthquake. Waves of up to 5.5 m in some coastal locations took 10-12 hours to cross the Pacific Ocean to reach our shores. The NEMA mobile phone alert that came out this afternoon urged people not to go tsunami sight-seeing at the coast. Let's take heed of this warning, and show that we have learnt something about tsunami risk by keeping clear of any waves or strong currents on our beaches, inlets and other coastal locations.' No conflicts of interest. Dr Jennifer Eccles, Senior Lecturer, School of Environment, University of Auckland, comments: 'The magnitude 8.8 earthquake that has struck in far Eastern Russia off the low population density Kamchatka Peninsula is sourced from the Kuril-Kamchatka arc subduction system, part of the Pacific Ring of Fire, where the Pacific Plate is subducting beneath the North American Plate (yes, Eastern Russia is on the North American tectonic plate). 'This has resulted in very strong shaking locally and also caused the Pacific Tsunami Warning Centre to issue potential threat warning to eastern Russia, Western North America and Japan with nearby coastlines feeling any impact first. Tsunami waves travel at speeds comparable to commercial aircraft will take some time to cross the Pacific Ocean with any impacts to New Zealand waters expected from midnight. By that time observations from coastlines impacted and marine DART (Deep-ocean Assessment and Reporting of Tsunamis) Buoys will allow a very good estimate of any potential coastal threat. Please see NEMA (The National Emergency Management Agency) for current advisories.' Conflict of interest statement: No conflicts declared. Dr Lauren Vinnell, Senior Lecturer of Emergency Management, Joint Centre for Disaster Research, Massey University, comments: 'Tsunami are a serious hazard, and they don't have to be very big to pose a threat. Anyone on the water or near the shore should take this warning seriously, as the expected currents and surges could be big enough to cause damage, injury, and threat to life. It is always better to be safe than sorry – if you act now to keep yourself safe and end up being fine, you can consider it as good practice for next time. 'For most of us, today's event can serve as a gentle reminder that we do need to think about tsunami and know how to respond. Sometimes, like today, there will be time to give warnings, but this won't always be the case if the tsunami starts closer to our shores. Remember, long or strong get gone – drop, cover, and hold during the shaking, and then if the shaking was longer than a minute or strong enough that it would be hard to stand, evacuate immediately uphill or inland. If in doubt, it is always best to evacuate. If today's event has you nervous, the best thing you can do is check your tsunami hazard zones, make sure you'd be ready to leave home quickly, and plan where you would evacuate to.' No conflicts of interest. Professor John Townend, earthquake scientist and Professor of Geophysics at Victoria University of Wellington, comments: 'Today's magnitude 8.8 earthquake near Kamchatka is the largest earthquake to have occurred worldwide since the magnitude ~9.1 Tohoku earthquake in 2011. 'Today's earthquake occurred in the subduction zone beneath the Kamchatka Peninsula, where the Pacific plate is moving WNW at approximately 75 mm/yr and being forced beneath the the Okhotsk plate that forms eastern Siberia and the Kamchatka Peninsula and in some studies is considered part of the North American plate. 'Given the earthquake's size and location, and preliminary seismological observations, it is likely to have involved slip of 10+ m over an area of ~150 x 400 km, although further analysis over the next 12-24 hours will be required to confirm this. Today's earthquake was preceded on 20 July by a magnitude 7.4 earthquake, now recognised as a foreshock. 'The depth, size, and faulting characteristics of today's earthquake combined to generate a tsunami that has already affected nearby coastlines and Japan and will have ongoing effects across the Pacific in coming hours. Today's earthquake released approximately 30x more energy than the 2016 magnitude 7.8 Kaikōura earthquake and approximately 3x less energy than the magnitude 9.1 Tohoku earthquake.' No conflicts of interest. Our colleagues at the UK Science Media Centre have also gathered comments on the earthquake and tsunami, climate change induced sea levels rises and potential impact on tsunami, and reports that the Fukushima nuclear site was evacuated due to the tsunami.
