Singapore Airlines has responded to the recent eruption of Anak Krakatoa by adding eight relief flights between Singapore and Jakarta. The eruption, which began on Friday, has caused significant disruption, affecting nearly 3,000 flights and over 340,000 passengers due to volcanic ash spreading across the region.3

The Geological Agency reported that the volcano's eruption lasted for 25 hours and reached heights of 50,000 feet (15,240 meters). Authorities have placed the volcano under the country’s second-highest alert status, indicating a high probability of further eruptions. The agency warned that the volcano could eject incandescent rocks and produce heavy ashfall, as well as lava flows.4

This event has raised questions about Indonesia's disaster preparedness and monitoring capabilities. The exceptional scale of the eruption has made its impact difficult to predict, leading to renewed discussions on how to strengthen the country's disaster planning.7

As the situation develops, the aviation industry is closely monitoring the effects of the eruption, with Singapore Airlines stepping in to provide additional flights to assist stranded passengers.
