Mount Semeru erupted dramatically, sending an ash cloud 54,000 feet high and prompting a red aviation warning by the Australia Volcanic Ash Advisory Centre. Authorities raised the volcano's alert to the highest level, evacuating over 300 residents and expanding the danger zone to an eight-kilometer radius. Rescue efforts are ongoing for around 178 people stranded near the crater, while officials monitor seismic activity for possible further eruptions.
