How Indonesia Volcano Eruption Shut Airports and Stranded 17,0000 Passengers in Jakarta

A volcano eruption at Mount Anak Krakatau triggered severe travel chaos across Southeast Asia this weekend. The disaster grounded more than 1500 flights and left 170000 passengers stranded.

The primary consern amongst people in regards of Indonesia volcano eruption reflect global concern as thick ash plumes drifted into critical flight corridors. The situation has led to the temporary shutdown of eight major airports in Indonesia including Soekarno-Hatta International Airport.

 Indonesia’s Transport Ministry confirmed that heavy ash fallout compromised air safety. A jakarta airport affected by volcano eruption notice remains active wherein local authorities monitor volcanic ash movement.

Why Indonesia Volcano Eruption Halts Air Travel in Jakarta

Volcanoes and jet engines do not mix. Unlike normal smoke volcanic ash is made of tiny bits of pulverised rock and glass. Those particles can melt inside the hot engine when an airplane flies through an ash cloud. The particle can even stick to the turbine blades and cause the engines to stall completely.

To keep everyone safe, Indonesia's transport ministry pulled the plug on flights across the area until the air cleared.

"The suspension at affected airports was extended because of increased eruptive activity," stated the official advisory from Indonesia's airport authority on Monday.

Which Airports and Cities Are Most Severely Impacted?

Jakarta’s Soekarno-Hatta hub suffered the highest volume of grounded flights due to volcano eruption in Indonesia. Over 900 flights have been cancelled, several regional gateways were forced to lock down when ash drifted northeast and southwest:

Major Shutdowns

Halim Perdanakusuma in Jakarta, Radin Inten II in Lampung, and Husein Sastranegara in Bandung.

School closures 

Authorities in Jakarta and Lampung ordered schools to move classes online to keep children indoors away from falling particulate matter.

Ground Operations

Ash coated vehicles and roads in Lampung, prompting health agencies to issue N95 mask advisories.

Lana Saria who is the head of Indonesia’s Geological Agency confirmed that "activity at Anak Krakatau has increased since July, with Sunday's eruption being the strongest recorded during that period." Officials also clarified that the activity does not pose an immediate tsunami risk.

Why Indonesia is Known as Most Volcanic Country?

Indonesia sits on the Ring of Fire which is a horseshoe shaped belt around the Pacific Ocean. Tectonic plates in this region constantly bump and slide against each other. 

That constant movement within Ring of Fire causes frequent earthquakes and feeds more than 120 active volcanoes across the country.

Take example of Mount Anak Krakatau which means "Child of Krakatau". It literally grew out of the water after the famous massive Krakatoa explosion of 1883. 

Because it lives right in the Sunda Strait between the huge islands of Java and Sumatra any big eruption of lava from its crater cuts right across busy shipping lanes and flight paths.

What Should You do If You are an Affected Passenger?

In case you or someone you know plans to travel from/to Java right now, it’s not enough just to appear at the airport and hope for the best.

1. Make sure you check the flight status with your airline through their app or website before leaving the room.

2. Some flights have been re-routed to other airports such as Surabaya or Semarang.

3. Wear an N95 mask in case you’re out on the streets in areas affected by downwind of the volcano.

The airports will resume sending flights once the upper winds clear the dust from above the runways.
