Magma recharging beneath the Weishan volcano of the intraplate Wudalianchi volcanic field, China | WHAT REALLY HAPPENED

Magma recharging beneath the Weishan volcano of the intraplate Wudalianchi volcanic field, China

A team of geophysicists warned that Wei Mountain in northeast China could be "recharging" for an eruption after two huge magma chambers were discovered under the volcano, which last erupted more than half a million years ago.

The researchers said they discovered two vast magma chambers under Wei in the Wudalianchi volcanic field in Heilongjiang, near the border with North Korea and Russia. The models indicate the chambers dwarf the volcano, which is about 100 m (330 feet) tall and 5 km (3 miles) wide.

The volcano's last eruption was more than 500 000 years ago and was already considered extinct, making the discovery a surprise to the geophysicists.

The researchers have been more focused on Changbai or Paektu Mountain, whose explosion in 946 A.D., was one of the strongest volcanic events in history. But the volcanic fields of Wei and Changbai "would be linked to some degree," the study noted.
