Tsunami warning: Horror moment waves from 8.8 magnitude quake smash Japan
Huge waves generated by a monster tsunami crashed against the coast in eastern Japan as two million people have been told to evacuate.
A tsunami hit coastal areas of Russia 's Kuril Islands and Japan's large northern island of Hokkaido after a powerful, 8.8-magnitude earthquake struck off the coast of Russia early today. Warnings are also in place for Alaska, Hawaii and other coasts south toward New Zealand. The Japan Meteorological Agency (JMA) said a tsunami as high as two feet had been detected as the waves moved south along the Pacific coast from Hokkaido to Tokyo Bay. Officials urged caution, saying that bigger waves could come later.
Damage and evacuations were reported in the Russian regions nearest the quake's epicenter on the Kamchatka Peninsula.
And footage from Kanagawa and Chiba in eastern Japan shows large waves crashing onto beaches with action plans now put in place in case coastal areas are flooded.
Japan's Fire and Disaster Management Agency said nearly two million residents are now under evacuation advisories in more than 220 municipalities along the Pacific coast as of midday Wednesday.
It added that one person was slightly injured on the northern island of Hokkaido when a woman in her 60s fell while rushing to evacuate. She was taken to a hospital.
Shiji Kiyomoto, a JMA earthquake and tsunami response official, said second or third tsunami waves of tsunami had arrived. Kiyomoto did not say when tsunami alerts would be lifted, and said high waves may last for at least a day, urging residents to stay at safe places.
Japan has suspended the operation of nuclear plants along the Pacific coasts amid concerns about a repeat of the 2011 Fukushima disaster. Authorities fear for the Fukushima Daiichi nuclear plant which is still a site of international scrutiny more than a decade later.
Tokyo Electric Power Company Holdings (TEPCO), which operates the facility, confirmed that around 4,000 workers had taken shelter on higher ground.
In the 2011 disaster, a series of waves, some as high as 14 metres, overwhelmed coastal defences and knocked out backup generators at Fukushima. That failure triggered a triple reactor meltdown, hydrogen explosions, and a mass release of radiation into the air and sea.
Tsunamis are waves triggered by earthquakes, underwater volcanic eruptions and submarine landslides. After an underwater earthquake, the seafloor rises and drops, which lifts water up and down. The energy from this pushes sea water that transfers to waves.
Many people think of tsunamis as one wave. But they are typically multiple waves that rush ashore like a fast-rising tide. Some tsunamis are small and don't cause damage. Others can cause massive destruction. In 2004, a 9.1 magnitude earthquake struck off the coast of Indonesia, causing waves that leveled remote villages, ports and tourist resorts along the Indian Ocean across Southeast and South Asia.

Japan moves to evacuate millions of people as torrential rain triggers flooding and landslides
Torrential rain triggered severe flooding and landslides across Japan 's Kyushu region on Monday, forcing authorities to call for the evacuation of millions of residents. In Kumamoto prefecture on Kyushu, Japan's southernmost main island, streets and neighbourhoods were submerged under about a metre of water, with rivers overflowing, vehicles swept away, and infrastructure heavily damaged, according to The Japan Times. Several people remained missing as rescue efforts continued on Monday. Tamana city in Kumamoto saw a record-breaking downpour of 37cm in just six hours, according to the Japan Meteorological Agency. While the highest-level rain alert was downgraded later in the day, officials warned that the saturated ground remained highly unstable, increasing the risk of further landslides. The Fire and Disaster Management Agency said more than three million people were under evacuation advisories, including hundreds of thousands facing Japan's most urgent warning level. There are reports of missing individuals in both Kumamoto and neighbouring Fukuoka prefecture, according to Japan's broadcaster NHK. In Kosa town, a man disappeared after a landslide reportedly struck near his home, while in Misato, emergency teams struggled to reach an elderly resident trapped by debris. 'Rain was so heavy that I couldn't see what's in front of me for four to five hours,' Misato town official Kazuhiro Masunaga was quoted as saying by The Japan Times. Japan's prime minister, Shigeru Ishiba, ordered an assessment of the damage and the mobilisation of government resources as sections of Kyushu's high-speed rail network continued to be disrupted. Extreme rainfall events like this are becoming more frequent in Japan due to a combination of seasonal weather patterns and the effects of climate change, experts believe. In mountainous regions such as Kumamoto, the risk is heightened – steep slopes combined with waterlogged soil can quickly collapse, setting off dangerous landslides.

Heavy rains in southern Japan cause flooding and mudslides, and leave several people missing
Downpours on Japan's southern main island of Kyushu caused flooding and mudslides, injuring a number of people and impacting travel during a Buddhist holiday week. Several people were reported missing. The torrential rain that began late last week left one person missing and four others injured in the southern prefecture of Kagoshima. The low-pressure system stuck over the region has since dumped more rain in the northern parts of Kyushu. The Japan Meteorological Agency early Monday issued the highest-level warning in Kumamoto. The Fire and Disaster Management Agency issued evacuation advisories to tens of thousands of people in Kumamoto and six other prefectures in the region. Rescue workers in the region were searching for several people. In Kumamoto, they were looking for three people. A family of three was hit by a mudslide while driving to an evacuation center. Two were dug out alive but a third person was still missing. Two others were missing elsewhere in the prefecture. Several other people were also reported missing after falling into swollen rivers in Kumamoto and nearby Fukuoka prefecture. Television footage showed muddy water gushing down, carrying broken trees and branches, and residents wading through knee-deep floodwater. Heavy rain also impacted people traveling during Japan's Buddhist 'bon' holiday week. Bullet trains connecting Kagoshima and Hakata in northern Kyushu, as well as local train services, were suspended Monday morning. About 6,000 households were out of power in Kumamoto, according to Kyushu Electric Power Co.

Heavy rain slams southern Japan, triggering floods and mudslides
Torrential rain pounded the southern Japanese island of Kyushu on Friday, triggering floods and landslides and sending residents to shelters as officials issued highest-level warnings in parts of the region. A mudslide hit a house in Aira city in Kagoshima prefecture, burying two people who were rescued alive and taken to hospital, according to the Fire and Disaster Management Agency. The agency issued evacuation advisories to more than 360,000 people in Kagoshima prefecture and neighboring Miyazaki. Television footage showed muddy water gushing down swollen rivers. In Kirishima city, floodwater was up to knee level at a shopping mall. The heavy rain paralyzed local transportation, halting trains and buses. Dozens of flights in and out of Kagoshima have been canceled. Prime Minister Shigeru Ishiba 's government set up a task force for emergency response and support. 'The government will do everything to protect your life and safety,' he said. The Japan Meteorological Agency predicted heavy rainfall and thunderstorms through Friday in Kyushu because of a low-pressure system.
