Short Answer 
The volcanic eruption in Bali is significant as it leads to the closure of the airport, directly disrupting air travel. Understanding the dangers posed by volcanic ash, such as engine damage and reduced visibility, is crucial, as historical events like the 2010 Eyjafjallajökull eruption illustrate the potentially widespread impact on airlines and travelers.
Step 1: Comprehend the Headline
The headline clearly states that a volcanic eruption is causing the closure of an airport in Bali. This situation is critical as it directly affects air travel, highlighting the immediate disruption to transportation due to natural events. Understanding this context is crucial for grasping the wider implications for travelers and airlines.
Step 2: Recognize the Risks of Volcanic Ash
Volcanic ash poses significant dangers to aircraft, making it imperative to understand these risks. Some of the dangers include:
- Damage to jet engines, which can lead to in-flight emergencies.
- Reduced visibility for pilots during flight operations.
- Flight disruptions, as airlines may need to cancel or reroute flights to ensure safety.
These factors emphasize why airport closures like the one in Bali are taken very seriously.
Step 3: Reflect on Historical Context
Historical incidents provide a framework for understanding current events. For example, the 2010 Eyjafjallajökull eruption in Iceland caused massive flight cancellations across Europe due to similar hazards. This past incident serves as a reminder of how volcanic eruptions can affect air travel on a large scale, reinforcing the importance of monitoring situations like the one in Bali.
