According to Japanese media reports, 601 volcanic earthquakes were observed at the Bandaiyama volcano in Fukushima Prefecture, Japan from noon on December 27 to 17:00 on December 28. This record broke the record for the most volcanic earthquakes at the Bandaiyama volcano on August 15, 2000. At present, volcanic earthquakes mainly occur in the mountain 2 kilometers northwest of the crater at a depth of about 2 kilometers.

The Japan Meteorological Agency stated that if volcanic earthquake activity continues, it will raise the volcanic eruption warning to level 2. However, the Bandaishan volcano warning level is still maintained at Level 1.

The Bandaiyama volcano is located in the northern part of Lake Inaashiro, Fukushima Prefecture, in the northeastern part of Honshu Island, Japan. It is a stratiform active volcano. The Bandaiyama volcano has an altitude of about 1,816 meters. The Bandaiyama volcano was first formed from about 1.1 million years ago to about 350,000 years ago. Afterwards, it went through many volcanic tectonic activities and eruptions and finally formed its current appearance.

The frequency of volcanic eruptions in the Bandai Mountain volcano since human activities were recorded is not many, mainly steam eruptions. The larger volcanic eruptions occurred in AD 806, 1787, and 1888 respectively. The deadliest volcanic eruption in history occurred on July 15, 1888. At that time, the eruption of Mount Bandai caused a huge mountain collapse and killed 477 people in total.
