The Hayli Gubbi volcano in Ethiopia’s Afar region erupted on Sunday for the first time in nearly 12,000 years, sending ash plumes up to nine miles high, according to the Toulouse Volcanic Ash Advisory Centre.

Ash clouds drifted across Yemen, Oman, India, and northern Pakistan as the subtropical jet stream carried the plume eastward.

Volcanologist Simon Carn confirmed that Hayli Gubbi has no known eruptions in the Holocene, making this event unprecedented in recorded history.

Local officials reported no casualties but warned that ash-covered grazing lands threaten the livelihoods of livestock-herding communities, CBS News has reported.

Residents described hearing a loud explosion and feeling a shock wave as the eruption began.
