The Hayli Gubbi volcano, located in Ethiopia's Afar region about 800 kilometres (500 miles) northeast of Addis Ababa near the Eritrean border, erupted on Sunday for several hours.

The volcano, which rises about 500 metres in altitude, sits within the Rift Valley, a zone of intense geological activity where two tectonic plates meet.

Ash clouds from the volcano drifted over Yemen, Oman, India, and northern Pakistan, the VAAC said.

In videos shared on social media, which AFP could not immediately verify, a thick column of white smoke can be seen rising.

The Smithsonian Institution's Global Volcanism Program said Hayli Gubbi has had no known eruptions during the Holocene, which began around 12,000 years ago at the end of the last Ice Age.

Simon Carn, a volcanologist and professor at the Michigan Technological University, confirmed on Bluesky that Hayli Gubbi "has no record of Holocene eruptions".

Afar authorities have not yet responded to AFP inquiries about possible casualties or the number of displaced people.
