Russia's major earthquake prompts string of 7 volcanic eruptions
The massive magnitude 8.8 earthquake that struck off Russia's Kamchatka Peninsula last week has triggered the activity of seven volcanoes in the area, according to the Institute of Volcanology and Seismology of the Far Eastern Branch of the Russian Academy of Sciences (RAS). The RAS said this is the first time in almost 300 years that seven volcanoes erupted at once in the region. Director of the institute Alexey Ozerov described the situation as an "extremely rare phenomenon that can be described as a parade of volcanic eruptions." The magnitude 8.8 earthquake that struck late on July 29 caused several aftershocks, including a magnitude 6 aftershock in the Pacific Ocean near Kamchatka at 6 a.m. local time Tuesday morning, according to the Kamchatka branch of the Unified Geophysical Service of the Russian Academy of Sciences. Among those erupting is the Klyuchevskoy Volcano, which the Kamchatka Volcanic Eruption Response Team reported to be spewing ash on Tuesday. The earthquake on July 29 has now caused the southern part of the Kamchatka Peninsula to shift southeastward, according to the local branch of the Russian Academy of Sciences' Unified Geophysical Service. The Kamchatka branch of the Federal Research Center "United Geophysical Service of the Russian Academy of Sciences have calculated the surface of the Earth shifted to the southeast, with the greatest shift occurred in the south of the peninsula reaching almost 2 meters. The greatest shift occurred in the south of the peninsula, movement that is comparable to the horizontal displacement that resulted from the 2011 earthquake in Japan. Seismologists acknowledge the peninsula has "shifted somewhat more modestly" although they do not specify the exact amount. The eruptions follow the volcanic activity of the Krasheninnikov Volcano that saw lava flow in the last week for the first time in nearly 600 years. Local officials said the last lava flow was recorded in 1463. A Russian seismologist told local media that there is a direct connection between last week's powerful earthquake and increased volcanic activity in Kamchatka. "We attribute the eruptions to the earthquake, which activated the magmatic foci and provided them with additional energy," Alexey Ozerov, a corresponding member of the Russian Academy of Sciences and director of the Institute of Volcanology and Seismology, told TASS, a state-affiliated media in Russia. The Krasheninnikov volcano is located less than 150 miles away from the epicenter of the earthquake that struck off the east coast of the Russian peninsula on July 29. The intense quake was one of the most powerful earthquakes ever recorded, and the world's largest since 2011. It spurred tsunmai warnings from Japan to Hawaii and the West Coast of the United States. Volcanic activity is common for the Kamchatka Peninsula, which is home to 29 active volcanoes, according to the U.S. Geological Survey, with three of those currently erupting previously laying dormant according to the RAS Massive eruptions began at 6 a.m. local time on Sunday, prompting the evacuation of personnel in the area, according to the Kronotsky Nature Reserve's website. The regional Ministry of Emergency Situations said there are no settlements along the ash plume's path of the Klyuchevskoy and said there are no registered tourist groups in the volcano's vicinity.

What to Know About Russia's ‘Historic' Volcano Eruption

Credit - Sheldovitsky Artem Igorevich—Institute of Volcanology and Seismology, FEB RAS When the sixth-strongest earthquake ever recorded hit Russia's Kamchatka Peninsula last week, it triggered tsunami warnings around the world as waves rippled across the Pacific as far as the U.S., Latin America, and even New Zealand. It also may have contributed to the eruption of a long-dormant volcano. Early Sunday on the same sparsely populated peninsula, the Krasheninnikov volcano spewed white ash clouds into the sky for the first time in hundreds of years. The Kamchatka Volcanic Eruption Response Team (KVERT) called it a 'historic' eruption. There is some discrepancy about when exactly the volcano's last known eruption took place. According to KVERT, Krasheninnikov's 'last lava effusion' occurred between 1423 and 1503. According to the Smithsonian Institution's Global Volcanism Program, it was around 1550. About 9.5 hours after the eruption began, KVERT issued an aviation red alert, warning aircraft of 'significant emission of ash into the atmosphere.' Satellite data indicated 'explosions sent ash up to 8-8.5 km a.s.l.' (appx. 5 mi). The volcano's activity decreased later Sunday, according to KVERT, which downgraded the aviation alert to orange, but as of Monday evening local time, the eruption remained ongoing, and KVERT warned that 'ash explosions up to 10 km (32,800 ft) a.s.l. could occur at any time.' No danger 'The plume is spreading eastward from the volcano toward the Pacific Ocean. There are no populated areas along its path. No ash falls were recorded in populated areas. There are no registered tourist groups in the area of the volcano,' the Main Directorate of the Ministry of Emergency Situations of Russia for the Kamchatka Territory posted on Telegram. KVERT said the ash plume had drifted more than 500 km (over 300 mi) by Monday evening. Krasheninnikov is located in the Kronotsky Nature Reserve, which said in a statement that there is no threat to any people or infrastructure as the volcano is largely surrounded by wastelands. 'Of course, a volcanic eruption is a vivid and interesting event, primarily for scientists,' Vsevolod Yakovlev, the director of the reserve, said in the statement. But, he added, Krasheninnikov's 'eruption is not something out of the ordinary for a region with high volcanic activity.' Indeed, the Kamchatka Peninsula was recognized in 1996 as a UNESCO World Heritage Site for its 'high density of active volcanoes.' The peninsula's Klyuchevskoy volcano, which is the largest active volcano in the northern hemisphere, erupted just hours after the 8.8 magnitude earthquake on July 30. A U.S. Geological Survey (USGS) representative told LiveScience that the quake 'did not cause' the eruption as the volcano was already 'showing signs of unrest' in the days and weeks before, though it likely intensified the 'vigor of the eruption including some ash emission.' How are earthquakes and volcanoes related? Earthquakes and volcanic activity both stem from the movement of the earth's tectonic plates. Volcanic and seismic activity are common at the boundaries of such plates. The Institute of Volcanology and Seismology of the Far Eastern Branch of the Russian Academy of Sciences said that there is a 'direct connection' between last week's historic earthquake and the activation of volcanoes that occurred after. The earthquake, the institute's director Alexey Ozerov said, 'activated magmatic centers, 'pumped' additional energy into them.' Krashennikov's eruption may not have been entirely triggered by the earlier, nearby 8.8 earthquake, Harold Tobin, a professor of seismology and geohazards at the University of Washington, told NPR. But, Tobin noted, the quake's seismic waves may have acted to 'shake loose the system that then allows it to actually erupt.' According to the USGS, earthquakes can sometimes trigger volcanic eruptions: 'A few large regional earthquakes (greater than magnitude 6) are considered to be related to a subsequent eruption or to some type of unrest at a nearby volcano.' According to the USGS, 'volcanoes can only be triggered into eruption by nearby tectonic earthquakes if they are already poised to erupt.' If there is already enough eruptible magma within the volcanic system and significant pressure within the magma storage region, large tectonic earthquakes might cause dissolved gases to come out of the magma, increasing the pressure and causing an eruption, the agency says, likening the effect to 'a shaken soda bottle.'

Russia cancels tsunami warning for Kamchatka after quake, dormant volcano erupts
Overnight, the Krasheninnikov volcano in Kamchatka erupted for the first time in 600 years, Russia's RIA state news agency and scientists reported on Sunday. The two incidents could be connected to the huge earthquake that rocked Russia's far east last week that triggered tsunami warnings as far away as French Polynesia and Chile, and was followed by an eruption of Klyuchevskoy, the most active volcano on the Kamchatka Peninsula. The Kuril Islands stretch from the southern tip of Kamchatka Peninsula. Russian scientists had warned on Wednesday strong aftershocks were possible in the region in the next few weeks. 'This is the first historically confirmed eruption of Krasheninnikov volcano in 600 years,' RIA cited Olga Girina, head of the Kamchatka volcanic eruption response team, as saying. On the Telegram channel of the Institute of Volcanology and Seismology, Girina said Krasheninnikov's last lava effusion took place within 40 years of 1463 and no eruption has been known since. The Kamchatka branch of Russia's ministry for emergency services said an ash plume rising up to 6,000m has been recorded after the volcano's eruption. The volcano itself stands at 1,856m. 'The ash cloud has drifted eastward towards the Pacific Ocean. There are no populated areas along its path,' the ministry said on Telegram. The eruption of the volcano has been assigned an orange aviation code, indicating a heightened risk to aircraft, the ministry said.

Long dormant Russian volcano erupts, spews ash 4 miles high
The Krasheninnikov Volcano near Kamchatka, Russia erupted overnight Sunday, spewing a plume of ash at least 3.7 miles into the sky. The volcano sits on the "Pacific Ring of Fire," known for high seismic activity, and is one of 8 active volcanoes in the region. Photo courtesy of the Institute of Volcanology and Seismology Aug. 3 (UPI) -- An eastern Russian volcano has erupted for the first time in more than 500 years, which may have been related to an 8.8 magnitude earthquake last week, experts said. The Krasheninnikov Volcano on the Kamchatka Peninsula emitted a plume of ash 3.7 miles into the sky overnight. The last recorded eruption of the volcano happened in the 15th century, the Kamchatka Volcanic Eruption Response Team said. Officials urged residents of the area to move away from the area, and volcano monitoring staff have been removed, though there have been no imminent threats to populated areas. No deaths have been reported. The Kamchatka Peninsula is located on the "Pacific Ring of Fire," known for the frequency volcanoes and earthquakes that occur there. Last week's massive earthquake was the latest in a series of seismic events in the region, including another temblor that shook a region 11 times zones away from Moscow on the Pacific peninsula, Russian seismic officials reported. The statement said the eruption occurred far from areas that could directly affect people. The volcano erupted at about 6 a.m. local time Sunday when staff observed gas and vapor spewing from Krasheninnikov's crater, officials said in a statement on social media. Officials in the volcano reserve called the eruption an "exciting and fascinating" event. Krasheninnikov is one of 8 volcanoes nestled among the reserve near Kamchatka.
