Huge ash columns erupted from Eurasia's tallest active volcano Wednesday, forcing authorities to close schools in two towns on Russia's sparsely populated Kamchatka Peninsula.
The eruptions from the Klyuchevskaya Sopka volcano sent ash as high as 13 kilometers (8 miles) above sea level, The Associated Press quoted officials as saying.
There were no reports of injuries, but officials ordered schools in Ust-Kamchatsk and Klyuchy closed as a precaution. Each town has a population of about 5,000. Klyuchy is located about 30 kilometers (20 miles) from the volcano and Ust-Kamchatsk 50 kilometers (30 miles) away.
The 4,650-meter (15,255-foot) stratovolcano has been active in recent years and released lava in June.
The Kamchatka Peninsula, which extends into the Pacific Ocean about 6,700 kilometers (4,100 miles) east of Moscow, is noted for its array of active and dormant volcanoes, geysers and geothermal springs.

South African scientists on Tuesday injected radioactive material into live rhino horns to make them easier to detect at border posts in a pioneering project aimed at curbing poaching.

The country is home to a large majority of the world's rhinos and as such is a hotspot for poaching driven by demand from Asia, where horns are used in traditional medicine for their supposed therapeutic effect.

At the Limpopo rhino orphanage in the Waterberg area, in the country's northeast, a few of the thick-skinned herbivores grazed in the low savannah.

James Larkin, director of the University of the Witwatersrand's radiation and health physics unit who spearheaded the initiative, told AFP he had put "two tiny little radioactive chips in the horn" as he administered the radioisotopes on one of the large animals' horns.

The radioactive material would "render the horn useless... essentially poisonous for human consumption" added Nithaya Chetty, professor and dean of science at the same university.

The dusty rhino, put to sleep and crouched on the ground, did not feel any pain, Larkin said.

The radioactive material's dose was so low it would not impact the animal's health or the environment in any way, he said.

In February the environment ministry said that, despite government efforts to tackle the illicit trade, 499 of the giant mammals were killed in 2023, mostly in state-run parks. This represents an 11 percent increase over the 2022 figures.

Twenty live rhinos in total would be part of the pilot Rhisotope project whereby they would be administered a dose "strong enough to set off detectors that are installed globally" at international border posts originally installed "to prevent nuclear terrorism", a pleased Larkin said, sporting a green hat and a khaki shirt.

Border agents often have handheld radiation detectors which can detect contraband in addition to thousands of radiation detectors installed at ports and airports, the scientists said.
