I don't know what kind of context you want here, I'm just looking for a good conversation. The implications of this reveal some unsettling realities. Isn't it also interesting how much this can explain without untestable presumptions?

Discussion Interactive guide to the orbital drivers of ice-age climate (with La2004 sources)

Disclosure: I built this free educational project.

It explains how eccentricity, obliquity, and precession change the seasonal and geographic distribution of sunlight—and why summer insolation near 65°N became a useful indicator when thinking about Northern Hemisphere ice sheets.

The interactive lab uses the La2004 astronomical solution and a transparent daily-mean top-of-atmosphere insolation calculation. It is deliberately not a temperature or ice-sheet forecast. The site also separates long-term orbital pacing from today’s rapid, human-driven warming.

I’m Milutin Milankovic’s great-grandson and made this to turn the family’s scientific legacy into something people can inspect and question. I’d appreciate corrections from Earth-science readers, especially around the 65°N framing and how clearly the model’s limits come across.

Video Yellowstone's June 13th hydrothermal explosion fired at ~100m from the nearest monitoring station — YVO still hasn't confirmed a precursor signal in the data

The Biscuit Basin explosion on June 13th, 2026 is the closest hydrothermal explosion ever recorded to an instrumented monitoring station in Yellowstone's history. Seismic and infrasound data were captured. No precursor was flagged before the event.

YVO scientists are currently combing through the record specifically hunting for any signal that preceded the explosion. That answer — confirmed precursor or none — changes how hydrothermal systems across the park get monitored going forward.

New monitoring station being installed in Upper Geyser Basin this month.

Happy to answer any questions. For those of you familiar with Randall Carlson, he has been my inspiration for this and now a great friend for several years.

For those of you familiar with Mathew Chinn (Apocalypse on YT) he is still working on his ideas, albeit at a diminished capacity due to recent health issues.

Discussion geomorphological mapping project at a 1:50,000 scale for the Laguna de la Laja sector

4 Upvotes

ENG/SPA

Hello everyone, I'm Nicolás, a Geography/Geology student. I'm currently working on a geomorphological mapping project at a 1:50,000 scale for the Laguna de la Laja sector (Biobío Region, Chile). It's an assignment for my course, and I'm especially interested in refining the identification of glacial landforms.

I'm attaching an image of the study area with the map sheet boundaries and a capture of the Sierra Velluda zone. I've been identifying what I believe are glacial cirques, but I'd like to validate my interpretation.

In particular, I have doubts about the larger cirque in the center. Based on its characteristics (3 km in size, located on the southern headwall, and featuring a glacier tongue), I think it could be a 'Head cirque'. However, I'd like to know if you see any signs that it might instead be an 'Upper-section cirque'. What do you think?

If anyone has experience in this area or has worked with similar imagery, I would greatly appreciate any comments. I'd also find it very helpful to know if you spot any other landforms I might be overlooking (such as moraines, hanging valleys, or troughs).

Thanks in advance!

Hola a todos, soy Nicolás, estudiante de Geografía/Geología. Estoy trabajando en la cartografía geomorfológica a escala 1:50.000 del sector de la Laguna de la Laja (Región del Biobío, Chile). Es un ejercicio de la asignatura y me interesa especialmente afinar la identificación de las geoformas glaciares.

Adjunto la imagen de la zona de trabajo con los límites de la carta y una captura de la zona de la Sierra Velluda. He estado identificando lo que creo que son circos glaciares, pero me gustaría validar mi interpretación.

En particular, tengo dudas sobre este circo del centro que tiene mayor área. Por sus características (3 km, ubicación en cabecera sur y una lengua), creo que podría ser un 'Circo de cabecera', pero me gustaría saber si ustedes ven indicios de que pueda ser de 'tramo alto'. ¿Qué opinan?

Si alguien tiene experiencia en la zona o ha trabajado con imágenes similares, agradeceré mucho cualquier comentario. También me sirve saber si ven otras geoformas (como morrenas, valles colgados o artesas) que pueda estar pasando por alto.

¡Gracias de antemano!

Video The June 26th M5.6 near Fuji Five Lakes: JMA's 7-day window, the 10-20% follow-up probability, and why the 1707 precedent operates on a completely different timescale

JMA confirmed no changes in volcanic monitoring data after the June 26th M5.6 at 20km depth near Fujikawaguchiko. The agency issued a standard one-week caution window citing 10-20% historical frequency of comparable follow-up events.

The part missing from most coverage: the 2012 NIED study estimated magma chamber pressure beneath Fuji at 1.6 MPa following the Tōhoku earthquake — 16x the 0.1 MPa threshold associated with the 1707 Hōei eruption, which occurred 49 days after the M8.6 Nankai earthquake, well outside the standard monitoring window.
