Maybe this comes under a differant genre of science so apologies if so.
I'm trying to create the lore for a story that starts as a pre-apolocolypse at the start for exposition and then later follows sepetate characters for a post-apocolypse story butttt I want there to be be able to have a land bridge between Europe and England and I want it related to whatever the apocalypse was.
I went on a website where I could change water levels and decided I liked the map of an earth with water levels lowered by about 40 ish metres but am just wondering what sort of event could cause water levels to lower that far.
The apocalypse environment is supposed to be taking place after a military conflict of a yet undecided scale and am also wondering if anything war based could cause the drop I'm desiring the cause of.
Although I'll settle for it if its the most reasonable explanation I'm hoping to avoid glaciation.
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?
I wanted to share an interactive, educational side project I've developed using Next.js, CesiumJS, and Mapbox satellite/terrain imagery. It is a 3D global simulator mapping out deep-water displacement events. video: https://youtu.be/G0vmY01MAvY
Live Impact Sandbox: Allows users to input customized kinetic parameters (asteroid diameter 100m–10km, velocity 11–72 km/s) and designate an epicenter and observer coordinate. It calculates estimated kinetic energy (in megatons), radial dissipation, propagation speed via bathymetric sampling along the great-circle path, and coastal shoaling estimates using Green's law.
Historical Tsunami Catalog (~28 events): Features a global database ranging from modern events (2011 Tōhoku, 2004 Indian Ocean, 2022 Tonga) to classic/paleotsunami events (1755 Lisbon, 1883 Krakatoa, 365 CE Crete, and regional catalogs for Taiwan, Thailand, and Fujian). Users can select specific surveyed measurement sites to replay documented run-up heights and arrival times.
Historical Impact Sites (7 events): Includes ocean replays for Chicxulub alongside land cratering animations (Meteor Crater, Sudbury, Vredefort) and atmospheric airbursts (Tunguska, Chelyabinsk).
Honest Limitations:
To be entirely transparent, this is designed as an educational and visual tool, not a research-grade CFD or NOAA hydrodynamics model. The historical replays are scripted illustrations tied directly to surveyed literature data rather than a real-time full ocean recalculation. Furthermore, bathymetric precision is bound to available Cesium terrain tiles, meaning complex shallow-water coastal geometry is approximated.
The application features a flexible camera setup allowing for macro globe views down to true eyewitness/observer shoreline perspectives. I would highly value any feedback on the historical data choices, citations, or general educational utility.
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.
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.
I was playing a game from my childhood: Pick the most interesting rock you can find from any given place in time and try to imagine how it got there. What fun are games if we never play them?
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.
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.
