In a move that surprised absolutely no one familiar with Indonesia's geology, Anak Krakatau has erupted again, grounding hundreds of flights and stranding tens of thousands of travelers at Jakarta's Soekarno-Hatta International Airport. The volcano, whose name literally means 'Child of Krakatoa,' apparently decided Sunday morning was a great time to remind everyone it exists.

Authorities reported that 209 flights were suspended after ash from the volcano was detected in airspace near the airport. The eruption began late Friday night, with continuous seismic activity, lava fountains, and booming sounds - nature's version of a dramatic entrance. Two more eruptions followed early Sunday, just to keep things interesting.

More than 22,000 people have been affected by the flight suspensions, which have been extended until 13:30 (0630 GMT). The transport ministry noted that flights to and from Singapore were hit hardest, but Doha, Sydney, and Kuala Lumpur also got a piece of the ash pie.

In a rare bit of good news, authorities confirmed there's no tsunami warning this time, unlike in December 2018 when the volcano collapsed and triggered a tsunami that killed over 400 people. Scientists later found that chunks of rock that slid off the volcano were about 70-90m high - because of course they were.

The health minister has advised residents in affected areas to stay indoors and wear face masks to protect against respiratory, eye, and skin issues. Local newspaper Kompas reported that several schools canceled activities on Saturday after students and residents experienced eye irritations. Some fishermen also canceled trips, citing sore eyes - a fishy excuse, but we'll allow it.

One resident, Aldi Candra Prayogi, told Kompas it felt like 'small grains of sand had gotten into my eyes,' and he's been using eye drops to ease the irritation. The dust is so thick he has to sweep his front yard every five minutes. Talk about a never-ending chore.

Anak Krakatau has been sporadically active since it emerged from the sea in the caldera formed after the 1883 eruption of Mount Krakatoa. It's a classic case of history repeating itself, with a volcanic twist. Indonesia sits on the Pacific Ring of Fire, where seismic and volcanic activity is about as common as traffic jams in Jakarta.

So, if you're planning to fly through Jakarta anytime soon, you might want to check with your airline - and maybe pack some eye drops.
