Elevated to the maximum alert level, the volcano’s ongoing tremors raise the risk of further explosions along with fast-moving mudflows.

Overview

  • PVMBG reported that the eruption at 11:00 local time sent an 18-kilometer ash column skyward and generated pyroclastic flows extending five kilometers north and northeast of the crater.
  • No injuries or fatalities have been reported so far despite the eruption’s intensity, though authorities deem further explosions possible.
  • Regional flights to Bali and Flores have been suspended and Maumere Airport remains closed until ash dispersion allows safe operations.
  • A six-kilometer exclusion zone has been enforced and residents are urged to wear masks and avoid river valleys at risk of fast-moving lahars.
  • Lewotobi Laki-Laki, part of a twin-volcano system that reactivated in late 2023, previously caused ten fatalities in a November 2024 eruption.
