Around 18:40 Japan Standard Time on August 25, 2026, a large-scale eruption occurred at the Manaro Volcano (Ambae Volcano) on Ambae Island in the Vanuatu archipelago, located in the south Pacific Ocean. According to observations by the Wellington Volcanic Ash Advisory Centre (VAAC) in New Zealand and the Himawari-9 meteorological satellite, the plume from the eruption is estimated to have reached an altitude of approximately 15,000 meters above sea level. In response to this massive eruption, the Japan Meteorological Agency (JMA) has begun investigating whether there will be any tsunami impact or arrival in Japan. Based on information from the JMA and other sources, if a tsunami were to be generated by pressure waves from the large-scale eruption and reach Japan, it is projected to arrive as early as around 22:30 on the same day in areas such as the Izu and Ogasawara Islands. Municipalities and relevant organizations across the country are closely monitoring the situation, urging resid...

On the morning of the 8th, an eruption occurred from the Ponmachineshiri crater of Mt. Meakan in Hokkaido. The volcanic plume reached approximately 100 meters above the crater and was observed flowing southeast. The Japan Meteorological Agency (JMA) is maintaining Volcanic Alert Level 2 (restriction around the crater) and is urging caution against large ballistic projectiles within a 500-meter radius of the crater. The eruption occurred around 9:15 AM and was still confirmed to be ongoing as of 10:00 AM. So far, no reports of significant ballistic projectiles or property damage have been received. While some local residents reported seeing plumes of smoke billowing from their windows, others calmly described it as a relatively minor eruption, saying things like, "It's definitely erupting, but it's small." Additionally, some residents have reported experiencing headaches, possibly due to the eruption. This eruption marks the first in approximately four and a half month...

On August 2, 2025, the Japan Meteorological Agency (JMA) successively announced that there was no concern for tsunamis reaching Japan following a large-scale volcanic eruption in Indonesia and earthquakes off Nemuro and Kushiro in Hokkaido that occurred on the same day. Indonesia Volcanic Eruption: Tsunami Concerns Dispelled Following a large-scale volcanic eruption in Indonesia, concerns about a tsunami temporarily spread across Japan. However, the Japan Meteorological Agency (JMA) announced, based on prompt observation and analysis, that there would be no tsunami impact on Japan from this eruption. While it is possible for atmospheric pressure waves caused by volcanic eruptions to affect the sea surface and generate tsunamis, no such phenomenon was observed with this particular eruption. In response to this quick report, numerous messages of relief were posted on social media, such as 'Thank you for the breaking news, so relieved there's no tsunami concern!' and 'What...
