Our small cruise ship had an excursion to "The Buried City". With 4500 residents, Montserrat can't exactly handle large ships!

Catalog notes for Trillium lot 4832

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 drew from Kircher's visit to Sicily in 1637-8 when Etna and Stromboli both erupted. This 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.

Taal Volcano in the Philippines has recorded a volcanic tremor lasting 31 hours and 44 minutes, alongside continuing ground inflation and a 1,800-metre plume. The latest activity follows multiple explosive eruptions earlier in October.

I was lucky enough to catch episode 43 of Kilauea’s ongoing eruption back in March and it was hands down the most incredible spectacle I’ve witnessed. The video doesn’t really do it justice!

Episode 43 is notable for featuring the tallest fountains (the South vent topped out at an estimated 1700 feet in height) and being the last episode to feature dual fountains. As of this writing, we just had episode 55 so either of these accolades can change in potential future episodes. Triple fountains would be awesome now that the west vent has emerged!

You can hear tephra falling in the background of the video. We were evacuated shortly thereafter as some of the tephra was football-sized. Got whacked in the head a couple times and it’s not a comfortable feeling. Better safe than sorry!

And yes, you can feel the heat off the fountains. This lookout is 1.5 miles away from the vent complex.

Thank you Pele for this experience! I am a rich man forever because of it🌋

Lassen Peak erupted from 1914 to 1917, and on 22 May 1915 a pyroclastic flow swept 6 km northeast of the summit. Lahars ran more than 20 km down Lost Creek.

B.F. Loomis, who ran a lumber mill in Viola, heard on 30 May 1914 that the peak was erupting. That June his six exposures put Lassen in the national spotlight, and he kept going back for a year to photograph it and guide geologists. His pictures backed the campaign for the national park, and in 1929 he gave it his museum and 40 acres.

In the lidar the summit's the rough mound at lower left. The grooved Devastated Area runs from it to the top middle.

It's difficult to find words how spectacular it was.

In the last 5 years the Palmero have built 3 roads across the lava flows, quite incredible really. The collapses in some of the craters where the lava flowed out are clearly visible. The recovery of the trees in the area is outstanding as well, really vibrant greens, and fruiting fig trees

I'm at Kilauea. I can hear the roar and feel its heat.

Featuring Rainer and Adams in the background, and the sunrise over Adams on the trek up. Incredible day and an incredible hike.

Kilauea has returned🌋🇺🇸

Give Me Some Recommendations, Thanks!

I’ve been cleaning out the house after my mother died, found this. 😭 I had forgotten about Mom always joking that she must have jinxed the island.

A relatively little-known volcano in the southern Andes, overshadowed by its imposing neighbors, Calbuco and Osorno. Its last eruption occurred around 210 ± 20 years BP.

There was actually more items I had with me to use in my photo shoot, but it was windy as hell (like it felt like 60+ mph winds at the Johnston Ridge Observatory) so I could barely stand anything for my photo shoot. 😭 But the ones I do have, I hope you enjoy

Crater Lake sits in the caldera left when Mount Mazama's eruption about 7,700 years ago destroyed the mountain. In 1870 a Kansas schoolboy named William Gladstone Steel read about it in the newspaper wrapped around his lunch.

In 1886 he had three boats hauled in for Clarence Dutton's USGS survey. They took 168 soundings with a lead weight on piano wire, and the deepest came out at 1,996 ft, a number that stood until 1958. Theodore Roosevelt signed the park into law on 22 May 1902, 17 years after Steel first saw it.

The lidar shows the steep caldera wall down the left side and Wizard Island's cone and summit crater left of centre.

I’m the developer of Mayon Volcano, an educational visualization of Mayon in Bicol, Philippines. This short recording shows part of the version 2.0 experience, The Living Mountain. Recording: actual app footage prepared in October 2026, created by Maha Strategies.

The surface terrain is built from NASA SRTM elevation data and Esri satellite imagery. Historical scenes cover 1814, 1968, 1984 and 2018, but the lava and eruption effects are reconstructions, not measured footprints or exact replays.

The underground views are conceptual models. Journey Inside and Follow a Crystal introduce evidence used to interpret volcanic systems, while evidence panels distinguish observations, inferences, illustrations and unresolved questions. The guided expeditions explore magma, volcanic evidence and the slow geological carbon cycle. Their interactive experiments are qualitative learning illustrations.

The Cagsawa Ruins marker, model and story viewpoint now share a corrected location in Busay, Daraga, thanks to u/Gin_Tagaubos pointing out the earlier error. The tower model remains approximate.

You can explore here: https://mayonrajan.com/

Core exploration, existing learning tools and the first two stops of each expedition are free. The optional Living Mountain Expedition Pack unlocks the three complete routes with one permanent purchase. Store launch pricing is US$6.99 in the US and ₱249 in the Philippines; local prices can vary. There’s no subscription.

I’d appreciate suggestions on which evidence or uncertainties deserve clearer explanation when presenting a volcano’s interior. This is an educational visualization, not a live monitoring or forecasting tool.
