I have a buddy who lives near Volcanoes National Park. He says his morning commute involves checking a volcano webcam instead of traffic reports. “If the glow’s orange, I grab my camera. If it’s red, I grab my go-bag,” he jokes. It’s that casual—like checking the weather, but with more lava.
But Kīlauea isn’t the only game in town. Just next door, Mauna Loa is the world’s largest volcano, a true heavyweight. It last erupted in 2026, and when it did, it painted the sky in shades of neon and sent tourists scrambling for viewpoints. Imagine your neighbor’s barbecue suddenly turning into a fireworks display—times a million.
Then there’s Hualālai, a sleepier neighbor that hasn’t erupted since 1801. Don’t let its quiet nature fool you. It’s like that coworker who never speaks up in meetings but could absolutely steal your job in a snap. Geologists say it’s resting, not retired.
Don’t Forget Maui and the Rest
If you’ve ever driven the winding road to Hāna, you’ve seen Haleakalā on Maui. This giant crater looks like a lunar landscape, which is why people bike down it at sunrise. It last erupted around 1600, so it’s very much on the “maybe” list. Think of it as the volcano equivalent of a long nap on a Sunday afternoon.
Up on the island of Hawaiʻi, Mauna Kea is technically dormant, but it sneaks onto the active list because it could, in theory, wake up. Right now, it’s more famous for its telescopes than its temper. You might hike it for the snow (yes, snow in Hawaii!), but you’ll be standing on a dormant giant.
Finally, we have Kamaʻehuakanaloa (formerly Lōʻihi). This one is underwater, about 22 miles off the Big Island’s coast. It’s the new kid on the block, still young and growing. Picture a baby dragon learning to breathe fire at the bottom of the ocean. It will take thousands of years to break the surface, but it’s already shaking things up with small earthquakes.
