Tsunami threat lifted in Russia's Kamchatka after powerful tremor
Its epicentre, according to the Kamchatka branch of the Unified Geophysical Survey of the Russian Academy of Sciences, was 115 km from the regional capital Petropavlovsk-Kamchatsky.
The larger quake was at a depth of 20 kilometers and occurred 144 kilometers east of the city of Petropavlovsk-Kamchatsky, which has a population of 180,000, according to the US Geological Survey.
A few minutes earlier, a quake with a magnitude of 6.7 was recorded nearby.
The PTWC initially said there was a danger of major tsunami waves but later downgraded its warning before finally saying the danger had passed.
According to Russian media, the tremors were felt for roughly a minute, causing people to run out of buildings. The press service of the Main Department of the Ministry of Emergency Situations in the region said that specialists will begin examination of the buildings as soon as possible.
Local services went into high alert mode. There were no immediate information of possible damage or casualties.
On 4 November 1952, a magnitude 9.0 quake in Kamchatka caused damage but no reported deaths despite setting off 9.1-meter waves in Hawaii.

Watch the video: Several injured in Russia after massive earthquake
One of the strongest earthquakes ever recorded struck off the coast of Russia on Wednesday, injuring several people, according to local authorities. The 8.8 magnitude earthquake's epicentre was around 119 kilometres from the Russian city of Petropavlovsk-Kamchatsky, which has a population of 180,000, on the Kamchatka peninsula. Tsunami waves reached as high as 10-15 metres in some sections of the Kamchatka coast, according to Russia's Oceanography Institute. Scientists expect aftershocks at magnitudes of up to 7.5, according to the local branch of the Russian Emergency Ministry. It said more tsunamis are possible near the regional capital of Petropavlovsk-Kamchatsky. Head of the regional health department Oleg Melnikov said several people were hurt as they left buildings and a hospital patient was injured. A local kindergarten was also reportedly damaged. All injured were in stable condition, Melnikov said. The Klyuchevskoy volcano, one of several on Russia's Kamchatka Peninsula, started erupting after the earthquake, according to local media. Authorities in the Kuril Islands in Russia's Far East introduced a state of emergency following the tsunami. The islands are situated in between Kamchatka and Japan. They reported flooding in the fishing port of Severo-Kurilsk, the main city on the islands, and downed electricity. The port's mayor said no significant damage was recorded, but that a tsunami alert remains in place. Tsunami waves were sent to Japan, Hawaii and other places across the Pacific after the earthquake in Russia. While no substantial damage has been reported so far, authorities are warning people to stay away from the shorelines.

Watch: Tsunami warnings sound in Japan after 8.8 magnitude quake off Russian coast
Tsunami warnings were heard in several northern and eastern coastal cities in Japan after an 8.8-magnitude earthquake struck off the Russian coast on Wednesday, July 30. "Residents in regions where warnings have been issued should immediately evacuate to safe locations such as elevated areas or evacuation buildings," said Japanese government spokesperson Yoshimasa Hayashi. The Japanese warning covered the entire northern and eastern coastline of the archipelago, extending as far south as Osaka and including the small surrounding islands. The tsunami could reach heights of up to 1 meter beyond these areas.

What are the strongest earthquakes ever recorded?
A powerful 8.8 magnitude earthquake struck the Far East region of Russia on Wednesday, generating tsunami waves that reached the coasts of Japan, Hawaii and Alaska. Authorities in several Pacific countries issued warnings for people to be on watch or evacuate to higher ground. The quake, considered one of the strongest in history, also triggered tsunami warnings in Latin America, as well as in Pacific islands as far south as New Zealand. Experts warn that the danger could last for more than 24 hours. The strongest earthquakes ever recorded The earthquake in Russia's Far East ranks among the top ten most powerful earthquakes in modern history. With a magnitude of 8.8, it is tied as the sixth strongest ever recorded and the biggest since the earthquake that hit Japan in 2011. Here is a look at where it sits amid the strongest on record, according to the US Geological Survey (USGS). A magnitude 8.6 earthquake occurred off the west coast of northern Sumatra. Although it caused little damage, it increased pressure on the fault line that triggered the devastating 2004 tsunami. At least 780 people were killed when an 8.6 magnitude earthquake struck the region. Dozens of villages were destroyed, one of them swept away by a river. Landslides blocked the Subansiri River, and when the water was released, it generated a deadly seven-metre wave. A magnitude 8.7 earthquake in this area triggered a tsunami with waves of up to 11 metres. There was minor damage, including cracks in buildings and runways. An 8.8 magnitude earthquake and subsequent tsunami caused around 1,500 deaths. Its effects were felt along the Central American coast and as far away as San Francisco and Japan. A powerful earthquake of magnitude 8.8 shook central Chile, including the capital Santiago. It lasted a minute and a half, generated a tsunami and left more than 500 dead. A magnitude 9.0 earthquake struck the Russian peninsula of Kamchatka, which was also affected this time. Although no fatalities were reported, it triggered a tsunami that reached as far as Hawaii with waves up to nine metres high. A magnitude 9.1 earthquake struck off the northeast coast of Japan, triggering a tsunami that directly impacted the Fukushima nuclear power plant. The disaster caused more than 18,000 deaths, in addition to a severe nuclear accident with meltdowns at three reactors. A magnitude 9.1 earthquake, followed by a devastating tsunami, struck Southeast Asia, South Asia and East Africa. An estimated 230,000 people died, more than 167,000 in Indonesia alone, where entire communities disappeared. Twenty years on from the earthquake last December, experts said that it was a "wake-up call" for understanding the dangers of these events. With a magnitude of 9.2, this earthquake shook Prince William Sound for nearly five minutes. More than 130 people were killed by the earthquake and the tsunami that followed. There were landslides and giant waves that caused massive flooding. Thousands of aftershocks were recorded in the following weeks. A magnitude 9.5 earthquake, known as the great Valdivia earthquake, devastated south-central Chile. It is the largest in recorded history and caused more than 1,600 deaths, most from the tsunami that followed. Thousands were injured.
