Mount Semeru Alert Raised After Series of Powerful Eruptions

Indonesian authorities have heightened the alert status for Mount Semeru following a series of strong eruptions on the country’s most densely populated island, Java.

Key Points

• Hot Ash Avalanches: The volcano in East Java province spewed avalanches of scorching clouds of hot ash and a mix of rock, lava, and gas, travelling up to 7 km down its slopes multiple times.
• History of Eruptions:
  • Mount Semeru, also called Mahameru, has erupted repeatedly over the last 200 years.
  • Despite risks, tens of thousands continue to live on its fertile slopes.
• Previous Major Eruption:
  • The last major eruption occurred in December 2021, killing 51 people and severely burning hundreds as villages were buried under thick mud and volcanic debris.
• Geological Context:
  • Indonesia, an archipelago of over 280 million people, lies along the Pacific Ring of Fire, making it highly prone to earthquakes and volcanic activity.
