Government experts monitoring Mount Shinmoedake for possible magma eruption
Mount Shinmoedake in the Kirishima mountain range straddling the prefectures of Kagoshima and Miyazaki erupted on June 22 for the first time since 2018.
Eruptions have continued. An ash plume rose 2,800 meters above the crater rim on Wednesday.
At a meeting of the government's volcano research committee held the same day, experts reported that massive amounts of volcanic gases have been emitted. While there are crustal movements suggesting there is swelling deep underground, an analysis of volcanic ash has found that no new magma has erupted.
Participants agreed that the situation does not call for an emergency meeting to be convened.
Shimizu Hiroshi heads the committee. He is also director-general of the Center for Volcanic Research Promotion at the National Research Institute for Earth Science and Disaster Prevention, or NIED.
While acknowledging that the assessment is his alone, Shimizu said at this point, what is happening at Mount Shinmoedake is not a magma eruption, but there is no denying that one could occur.
He said careful monitoring is needed to assess whether the swelling deep underground accelerates.
The meeting came as the alert level for Mount Shinmoedake remains at Level 3 on a 5-point scale.
Japan's Meteorological Agency is warning of falling volcanic rocks and pyroclastic flows within a 3-kilometer radius of the mountain.

Taiwanese rocket fails to achieve Japan's first foreign launch
Taiwanese private rocket company TiSpace terminated the flight of one of its rockets shortly after lift-off in northern Japan on Saturday, failing to become the first foreign company to perform a successful launch on Japanese soil. TiSpace, through its Japanese unit jtSPACE, tried to reach outer space 100 kilometers above the Earth's surface on the inaugural flight of its 12-meter, hybrid-fuelled rocket VP01 in a launch from Japan's Hokkaido Spaceport. The rocket lifted off at 11:40 a.m., but within a minute its trajectory turned wobbly and it went into free fall, footage from Japanese public broadcaster NHK showed. "We are examining the situation of the flight," a spokesperson for Space Cotan, the Japanese company operating the Hokkaido Spaceport, said after the launch attempt. The rocket did not carry a satellite, although Space Cotan has said its success would be a step toward building a satellite-launching vehicle. TiSpace, led by a former Taiwan Space Agency official, has not had a successful spaceflight. It turned to Japan in search of a test site after failing to launch a rocket in Australia in 2022. While local officials and businesses in Hokkaido welcomed the move as a milestone toward becoming an international space hub, some Japan space policy experts have worried about provoking China, which closely monitors Taiwan's advances in missile-related technologies. In Japan, private rocketmakers are racing to gain entry to the commercial launch market dominated by Elon Musk's SpaceX and U.S. rivals including Rocket Lab. No privately developed Japanese rocket has achieved orbital satellite launch. Interstellar Technologies, a Hokkaido-based startup now backed by Toyota, was in 2019 the first private rocket venture in Japan to reach space, although without a satellite payload. Canon Electronics-backed Space One conducted two failed orbital launches last year. Carmaker Honda last month succeeded in a low-altitude test of its prototype reusable rocket in Hokkaido, pledging to achieve spaceflight by 2029.

Taiwan-made rocket stops flight mid-ascent in Hokkaido
A Taiwanese-made rocket was launched at the Hokkaido Spaceport in Taiki Town, Hokkaido, on Saturday, but it stopped flying during the ascent and did not reach its planned altitude of 100 kilometers. The 12-meter, two-stage rocket lifted off at around 11:40 a.m. It was manufactured by a Taiwanese company. According to the company that manages the spaceport, the rocket stopped flying during its ascent. The company said the first stage of the rocket was confirmed to have separated, but the flight of the second stage was suspended later. Footage taken by NHK shows the second stage of the rocket continuing its flight while rotating and falling. Police say no injuries have been reported. The launch was performed by a foreign company in the same group as the Taiwanese manufacturer of the rocket.
