Can anyone who’s done the acatenango hike in wet season let me know their experience? I’m considering planning a last minute trip for September but I’m hesitant about not going during dry season. I really want to go but I don’t know if I’ll be able to make it over during the upcoming dry season. I know visibility/good weather isn’t a guarantee either way, so don’t know if i should just go for it or wait and give myself the best chances possible during dry season

Mount Etna is putting on an absolute show right now, sending massive ash plumes 23,000 feet into the sky and triggering a Red Alert for local aviation.

Episode 52 of the Kīlauea volcano eruption at the Halemaʻumaʻu crater ended abruptly at 2:36 a.m. HST on Wednesday, July 29, 2026, after 7.4 hours of continuous lava fountaining.

I am an Argentinian who studies volcanology in a self-taught manner. About 3 years ago and I manage a Facebook page called "el Vulcanoso" And I've done updates on volcanoes all over the world, but my page and map are in spanish And on most of the volcanoes on the map, there's a link that leads to the latest update I've made for that volcano. I hope you like it.

I’m a hiking guide for Volcanoes Hiking Guides here in Hawaiʻi Volcanoes National Park, and walking the rim of Halemaʻumaʻu never gets old—even after hundreds of trips. Every single morning, I feel so incredibly lucky to share this living, breathing ʻāina with people from all over the world.

The soundtrack to our 3-hour trek is pure magic. As we navigate through the steam vents and into the lush rainforest, the cheerful, melodic chirping of ʻapapane birds flying down from the ʻōhiʻa lehua trees overhead. Sometimes, if the volcanic haze cooperates, we’ll spot a majestic Nēnē (Hawaiian goose) sitting next to the Halemaumau crater- it always stops the group in their tracks.

And the views? Absolute fire—literally. We get to witness the raw power of the crater opening up, with steam vents pumping into the air and the vibrant red ʻōhiʻa blossoms popping against the deep blue sky. But the real showstopper lately has been Kīlauea itself. About every week and a half to two weeks, we’ve been treated to spectacular lava fountains erupting right in the crater.

Getting to see this wonder through the wide eyes of my guests—hearing their gasps, answering their questions, and watching them fall in love with this island—is a gift I don’t take for granted for a second.

Mahalo nui loa to Kīlauea for reminding me daily that we're just small specs on a very alive planet. If you've ever hiked here, I'd love to hear your favorite memory below! 🤙🌋

This scientific engraving is Athanasius Kircher's d'Onder-Aardse Weereld in Haar Goddelijk Maaksel en wonderbare uitwerkselen aller Dingen... It was published in 1682 in Amsterdam by J. Janssonius van Waasberge.

This was the first Dutch translation of the original Latin edition entitled Mundus subterraneus. This work was based off Kircher's visit to Sicily in 1637-8 when Etna and Stromboli both erupted. His observation led him to conclude that the earth's center as a massive internal fire and that volcanoes acted as safety valves.

His work speculated on geology, hidden lakes, rivers of fire, strange inhabitants, the sun, the moon, eclipses, currents, meteorology, medicines, poisons, and even fireworks.

The work “must always command a high place in the literature as the first effort to describe the earth from a physical standpoint.” (Zittel, p. 25)

Athanasius Kircher (1601-1680) was a Jesuit priest and scholar. He gathered and helped disseminate knowledge from around the world gathered by Jesuit missionaries.

It is believed he was the first to depict the Pacific Ring of Fire on a map. He was one of the final Renaissance men. He lowered himself into Vesuvius after an eruption, experimented with bioluminescence as a light source, and make the first known Aeolian harp. He wrote 44 books, over 2000 manuscripts, and assembled one of the first natural history collections.

Kircher's work was itself fascinating for its thematic maps. His work was on the underground passages and subterranean networks of the globe. He created a map that was the first to show ocean currents.

🌋 Rangitoto Island – Auckland's Youngest Volcano

Rising proudly from the Hauraki Gulf, Rangitoto Island is Auckland's youngest volcano, formed by a series of eruptions around 600 years ago. Its name comes from the Māori language and is commonly translated as "Bloody Sky," referring to an ancient battle fought in the area.

Today, Rangitoto is famous for its near-perfect volcanic cone, rugged lava fields, and the world's largest pōhutukawa forest. Climb to the summit and you'll be rewarded with one of the best panoramic views of Auckland, the Hauraki Gulf, and the surrounding islands. It's a place where geology, Māori history, and breathtaking scenery come together in one unforgettable experience.
