Volcanic ash from eruptions can reshape cirrus clouds, forming giant ice crystals and altering how Earth traps heat in the atmosphere.

ONE of the world’s most active volcanoes has erupted again in Hawaii, spewing nearly 1,000ft lava jets into the sky. That’s nearly as high as the Eiffel Tower. Footage of the

Carbon dioxide emissions from rising magma is one of the earliest signs that a volcano is waking up, but measuring it directly is notoriously difficult.

Japan’s Sakurajima volcano erupted on May 15, 2025, releasing toxic gases and ash that pose serious health risks, including respiratory issues, burns, and even suffocation.

Nearly a mile deep, the Pacific Ocean volcano known as Axial Seamount is drawing increasing scrutiny from scientists who only discovered its existence in the 1980s.

Oxford researchers found that changes in shear-wave splitting can predict volcanic eruptions and their severity. The signal shifted noticeably before a major eruption at Ontake Volcano, offering a promising early warning tool.

A researcher monitoring Axial Seamount, 300 miles off the coast of Oregon, says the eruption is expected to happen before the year is over.

A volcano eruption near Oregon is brewing — but don ... you probably would never know it’s erupting, as there’s no effect on the ocean surface,” Chadwick previously said.

The Japan Meteorological Agency plans to issue ashfall warnings and advisories in the event of an eruption on any of the country’s 111 active volcanoes, including Mount Fuji.
