New island emerges after undersea volcano erupts off Japan, but experts say it may not last long
TOKYO (AP): An undersea volcano erupted off Japan three weeks ago, providing a rare view of the birth of a tiny new island, but experts say it may not last very long.
The unnamed undersea volcano, located about 1 kilometer (half a mile) off the southern coast of Iwo Jima, which Japan calls Ioto, started its latest series of eruptions on Oct. 21.
Within 10 days, volcanic ash and rocks piled up on the shallow seabed, its tip rising above the sea surface. By early November, it became a new island about 100 meters (328 feet) in diameter and as high as 20 meters (66 feet) above the sea, according to Yuji Usui, an analyst in the Japan Meteorological Agency's volcanic division.
Volcanic activity has increased near Iwo Jima and similar undersea eruptions have occurred in recent years, but the formation of a new island is a significant development, Usui said.
Volcanic activity at the site has since subsided, and the newly formed island has somewhat shrunk because its “crumbly” formation is easily washed away by waves, Usui said.
He said experts are still analyzing the development, including details of the deposits. The new island could survive longer if it is made of lava or something more durable than volcanic rocks such as pumice.
“We just have to see the development,” he said. “But the island may not last very long.”
Undersea volcanos and seismic activities have formed new islands in the past.
In 2013, an eruption at Nishinoshima in the Pacific Ocean south of Tokyo led to the formation of a new island, which kept growing during a decade-long eruption of the volcano.
Also in 2013, a small island surfaced from the seabed after a massive 7.7-magnitude earthquake in Pakistan. In 2015, a new island was formed as a result of a month-long eruption of a submarine volcano off the coast of Tonga.
Of about 1,500 active volcanos in the world, 111 are in Japan, which sits on the so-called Pacific “ring of fire,” according to the Japan Meteorological Agency.
Iwo Jima was the site of some of the fiercest fighting of World War II, and the photograph taken by AP photographer Joe Rosenthal of the flag-raising atop the island's Mount Suribachi on Feb. 23, 1945, came to symbolize the Pacific War and the valor of the United States Marines.

Minister Patil chairs industry meetings to chart growth for key sectors in Karnataka
Bengaluru (PTI): Karnataka Minister M B Patil on Tuesday chaired meetings with industry representatives from the aerospace and defence, machine tools, auto/EV, and green energy sectors to discuss sector growth and government support measures.
The meetings were attended by leading industrialists and their representatives, with some participating virtually.
Speaking on the occasion, the minister for Large and Medium Industries said Karnataka is at the forefront of the country’s aerospace and defence sectors.
He noted that Suzuki and Toyota plan to launch aerial taxi services in Japan by 2028, with Bengaluru-based Sasmos supplying electrical equipment for the project.
Industrialists suggested introducing similar “fly-taxi” services in Karnataka through an appropriate policy, which Patil said would be examined seriously.
The minister highlighted the need to establish testing centres and Common Facility Centres for the aerospace and defence industries and assured that these facilities would be provided.
Suggestions were also made to prepare a comprehensive roadmap for sector growth.
Karnataka has urged the Central Government to approve Defence Corridor projects in the Bengaluru North–Kolar–Chikkaballapur and Dharawada–Vijayapura–Belagavi regions.
Industrialists also suggested a corridor between Bengaluru and Mysuru, Patil said.
He said Karnataka aims to become a hub for defence electronics manufacturing, with plans to establish a 200-acre Defence Electronics Park and a 100-acre Avionics and Sensor Park.
These projects will be implemented once the Special Investment Region is operational, and land availability will not be an issue.
On the machine tools sector, Patil said the industry has recorded an annual turnover of Rs 36,500 crore and is witnessing steady growth.
Large-scale exhibitions have increased demand, and the state must strengthen its capabilities to develop control systems for heavy machinery. One testing unit is already operational in Bengaluru, with another planned for Tumakuru. Expansion of vocational training institutes in industrial areas is also underway.
In the Auto and EV sector, Vision Group members highlighted the need for a network of dry ports and more EV charging stations across the state.
Patil noted that the Tata Group is manufacturing EV buses in Dharawada for nationwide supply. Plans for mini excavator production and export facilitation were also discussed, along with the establishment of a testing facility for two-wheeler EVs.
For the Green Energy sector, the group emphasised the need for a suitable policy on battery-based energy storage and the establishment of data centres.
Patil assured that the government will seriously consider all suggestions and respond positively.
