The land around a strange volcano in Tanzania is bulging, suggesting magma may be accumulating in a shallow reservoir beneath the surface. The movement could be a precursor to an eruption, researchers say.
Ol Doinyo Lengai is an active volcano that erupts the runniest lava on Earth. Satellite data indicate that a magma reservoir about 1.4 miles (2.3 kilometers) beneath the crater began swelling in March 2022, suddenly stretching Earth's crust above it. This rapid uplift continued at a steady rate until December 2022, and then gave way to a period of slower uplift that lasted through to August 2023, according to a new study.
