The Japan Meteorological Agency downgraded a tsunami warning to an advisory in Okinawa prefecture after a 7.3-magnitude earthquake near Taiwan caused a 30cm tsunami in Yonaguni and small waves in Ishigaki and Miyakojima islands. Flights were suspended at Naha airport, and warnings of potential 3-meter tsunamis were issued. Japan, Taiwan, and the Philippines issued tsunami warnings due to the earthquake in Taiwan. Residents were urged to evacuate to higher ground as sea level changes were detected on the southern side of Japan, with waves potentially reaching 9.8 feet high.
Taiwan experienced a powerful earthquake with an estimated magnitude of 7.7, leaving one person dead, over 50 injured, and many trapped in collapsed buildings. Coastal areas in Japan were urged to evacuate due to tsunami warnings. The quake damaged buildings, caused power outages for over 87,000 households, and disrupted train and metro services in Taiwan. Aftershocks were felt, and tsunami advisories were lifted. The earthquake was felt as far as Shanghai in China.
A 7.4 magnitude earthquake hits off Taiwan's east coast, causing tsunami warnings in Taiwan and neighbouring nations. The quake's epicentre is near Hualien city, leading to building collapses and landslides. TSMC evacuates factories for safety. Japan and the Philippines issue tsunami warnings. The quake, Taiwan's strongest in 25 years, causes power cuts, internet outages, and aftershocks.
On 1 January 2024, at 16:10 JST (07:10 UTC), a MJMA7.6 (Mw7.5) earthquake struck 6 km (3.7 mi) north-northeast of Suzu, located on the Noto Peninsula of Ishikawa Prefecture, Japan. The reverse-faulting shock achieved a maximum JMA seismic intensity of Shindo 7 and Modified Mercalli intensity of X–XI (Extreme). The shaking and accompanying tsunami caused widespread destruction on the Noto Peninsula, particularly in the towns of Suzu, Wajima, Noto and Anamizu, with the neighbouring prefectures of Toyama and Niigata also recording significant damage. As of 26 March 2024, there were 244 deaths confirmed and five people remaining missing, all of them in Ishikawa, with 1,297 others injured across six prefectures, making it the deadliest earthquake in Japan since the 2016 Kumamoto earthquakes. As of 20 February, 12,929 people remained in 521 evacuation centers.The Japan Meteorological Agency (JMA) officially named this earthquake the 2024 Noto Peninsula Earthquake (Japanese: 令和6年能登半島地震, Hepburn: Reiwa 6-nen Noto-hantō Jishin). It led to Japan's first major tsunami warning since the 2011 Tōhoku earthquake, and a tsunami of 6.58 m (22 ft) was measured along the Sea of Japan coast.
A 6.1-magnitude earthquake struck off Japan's Iwate prefecture early Tuesday at a depth of 80 km, measuring lower 5 on Japan's seismic intensity scale. The epicenter was off Iwate prefecture's northern coast with no tsunami warnings issued, and no immediate reports of damage.
The Japan Meteorological Agency (気象庁, Kishō-chō), abbreviated JMA, is an agency of the Ministry of Land, Infrastructure, Transport and Tourism. It is charged with gathering and providing results for the public in Japan that are obtained from data based on daily scientific observation and research into natural phenomena in the fields of meteorology, hydrology, seismology and volcanology, among other related scientific fields. Its headquarters is located in Minato, Tokyo.JMA is responsible for gathering and reporting weather data and forecasts for the general public, as well as providing aviation and marine weather data. JMA's other responsibilities include issuing warnings for volcanic eruptions and the nationwide issuance of earthquake warnings of the Earthquake Early Warning (EEW) system. JMA is also designated one of the Regional Specialized Meteorological Centers of the World Meteorological Organization (WMO). It is responsible for forecasting, naming, and distributing warnings for tropical cyclones in the Northwestern Pacific region, including the Celebes Sea, the Sulu Sea, the South China Sea, the East China Sea, the Yellow Sea, the Sea of Japan and the Sea of Okhotsk.
The Japan Meteorological Agency (JMA) Seismic Intensity Scale (known in Japan as the Shindo seismic scale) is a seismic intensity scale used in Japan to categorize the intensity of local ground shaking caused by earthquakes.The JMA intensity scale should not be confused or conflated with magnitude measurements like the moment magnitude (Mw) and the earlier Richter scales, which represent how much energy an earthquake releases. Much like the Mercalli scale, the JMA scheme quantifies how much ground-surface shaking takes place at measurement sites distributed throughout an affected area. Intensities are expressed as numerical values called shindo (震度, "seismic intensity"); the higher the value, the more intense the shaking. Values are derived from peak ground acceleration and duration of the shaking, which are themselves influenced by factors such as distance to and depth of the hypocenter (focus), local soil conditions, and nature of the geology in between, as well as the event's magnitude; every quake thus entails numerous intensities.The data needed for calculating intensity are obtained from a network of 670 observation stations using "Model 95" strong ground motion accelerometers. The agency provides the public with real-time reports through the media and Internet giving event time, epicenter (location), magnitude, and depth followed by intensity readings at affected localities.
62 million people across the Northeastern United States woke up under wind advisories and high wind warnings, with wind speeds forecasted to reach up to 60 mph in some areas. Flights are experiencing delays, power outages and downed trees are expected, and flooding is still a concern in parts of New Jersey. The storm system also brought light to moderate snow in the interior Northeast and New England. Numerous areas are facing wettest starts to March on record, and coastal flooding is a significant issue, especially in vulnerable areas like Hampton Beach, New Hampshire.
Japan's experts have met with Chinese counterparts to address Beijing's concerns regarding the release of treated radioactive wastewater from the damaged Fukushima Daiichi nuclear power plant into the sea. China has banned imports of Japanese seafood in opposition to these discharges, affecting scallop growers and exporters. The talks involved scientific explanations of the safe discharge process, initiated after a 2011 disaster led to the accumulation of radioactive water. The countries' leaders agreed to these discussions, aiming for transparency and technical clarity around the issue.
Taiwan, officially the Republic of China (ROC), is an island country in East Asia. The island of Taiwan, formerly known as Formosa, makes up 99% of the land area of the territories under ROC control. The main island is 35,808 square kilometres (13,826 sq mi) and lies some 180 kilometres (112 mi) across the Taiwan Strait from the southeastern coast of the People's Republic of China (PRC). The East China Sea lies to the north of the island, the Philippine Sea to its east, the Luzon Strait directly to its south and the South China Sea to its southwest. The ROC also controls a number of smaller islands, including the Penghu archipelago in the Taiwan Strait, the Kinmen and Matsu Islands in Fuchien near the PRC's coast, and some of the South China Sea Islands.Geologically, the main island comprises a tilted fault block, characterized by the contrast between the eastern two-thirds, consisting mostly of five rugged mountain ranges running parallel to the east coast, and the flat to gently rolling plains of the western third, where the majority of the population resides. Several peaks exceed 3,500 m in height - the highest, Yu Shan at 3,952 m (12,966 ft), makes Taiwan the world's fourth-highest island. The tectonic boundary that formed these ranges remains active, and the island experiences many earthquakes, some of them highly destructive. There are also many active submarine volcanoes in the Taiwan Straits.The climate ranges from tropical in the south to subtropical in the north, and is governed by the East Asian Monsoon. On average, four typhoons strike the main island each year. The heavily forested eastern mountains provide a habitat for a diverse range of wildlife, while human land use in the western and northern lowlands is intensive.
