Hawaiʻi Volcanoes: How to Protect Yourself from Kīlauea's Tephra

If you're planning a visit to Kīlauea's summit, a quick safety check is worth it before you head out. The park is currently flagging tephra across the area, and that's worth a moment's attention while you pack your bag.

Behind that slightly technical word is a very real mix: volcanic ash, rock fragments, and thin strands of volcanic glass thrown out by the volcano's activity. These particles aren't dangerous to look at, but they turn irritating on contact. They can bother your skin, eyes, and airways if you stay exposed without protection.

The first rule is simple, and it's the one the park stresses: don't touch the tephra with your bare hands. The temptation is real when you come across those bits of volcanic glass on the ground, but you're better off leaving them where they are. That one habit heads off most of the minor skin irritation.

As for gear, a few items are enough to tour the summit with peace of mind. Bring eye protection, long sleeves, and long pants instead of shorts. Add a hat, closed-toe shoes (skip the sandals that day), and a dust mask so you can breathe a little easier. Nothing fancy: most of this already fits in a standard day pack.

This kind of precaution shouldn't put you off coming. Kīlauea is still one of the most impressive volcanic sites you can visit, and staying alert is simply part of the experience at a park that's very much alive. Gear up right and you'll take in the scenery with a clear head.
