On August 10, 2026, a magnitude 7.5 earthquake tore 118 km beneath western Colombia (Chocó region). Intermediate-depth earthquakes typically lose considerable energy before reaching the surface, yet this rupture triggered over $13B in losses.

A few key takeaways from our simulation and intensity modeling:

I put together a full seismic intensity simulation and structural failure breakdown covering the science behind the event:

Happy to answer any questions about the rupture parameters or simulation models!

I feel like E is lowkey good you’re either Russian or Norwegian

Hey everyone, Michael here.

I have been hiking for about ten years, but last year i have developed depression which, sadly, made me stay at home and in bed mostly.

I spoke to my psychiatrist and he said that i should combine something i love with something i can do and i decided to make a YouTube channel about tragedies (xd) in mountains.

I have created my first video today finally after many tries and would greatly appreciate my fellow hikers to support it and leave some feedback :)

First known victim of these mountains - accident or murder?

🇬🇧 This year, the Graphic Design Biennale of Chaumont (France) centers on the theme "Borders, spaces and limits". Our graphic design teacher encouraged us to enter the competition. To bring my project to life, I need help from people all over the world!

Your part will be to share your personal testimony on what borders represent in your country: how are they perceived, viewed, and experienced in the collective mind and/or through your own perspective? This can be at the scale of your entire country, your area, or even your city.

To send a clear and precise answer, please include your first name (you may use a pseudonym if you prefer, but please keep your actual location), your country or geographical area, and your testimony. It should be concise while clearly capturing your experience, as these texts will be featured on posters and cannot be too long.

Thank you so much for your precious help!

🇫🇷 Cette année, la Biennale de design graphique de Chaumont (France) a pour thème « Frontières, espaces et limites ». Notre professeur de graphisme nous a encouragés à participer. Pour concrétiser mon idée, j'ai besoin de votre aide aux quatre coins du monde !

Votre rôle sera de me transmettre votre témoignage sur ce que représentent les frontières dans votre pays : comment sont-elles perçues, envisagées et vécues dans l'esprit collectif et/ou selon votre propre perception ? Cela peut être à l'échelle de votre pays tout entier, de votre région, ou même de votre ville.

Pour m'envoyer une réponse claire et précise, il faudra m'indiquer votre prénom, votre pays ou zone géographique, ainsi que votre témoignage. Ce dernier doit être concis tout en traduisant fidèlement votre pensée. Vos textes seront intégrés dans des créations d'affiches, le texte ne doit donc pas être trop long.

Merci beaucoup pour votre aide !

Why is India so much greener compared to Tibetan plateau, are Himalayas playing a big role?

Another question is why are there so many lakes in Tibet

Hello!

I am a land Surveying student whos (heavily) thinking about changing to Geography.

I went into land surveying thinking that I could help the environment and conserve land and I've found that Land Surveying is just working for construction projects and developments.

That is not what I want to spend my life doing.

I want to conserve land across the earth, not make it easier to sell it or build on it.

Since I've been studying this major (2 full years now) I have made it my mission to find any Land Surveying professional that has a job or an interest in conservation or helping conserve land and not one of them has.

I know that their lives aren't mine, but its very discouraging.

I have been doing my research on Geography and so far I've loved the possibilities a degree in Geography brings. I've talked with a Geographer on linked in and he even works in disaster recovery which is so so amazing.

To further my research I would love if any Geographers or knowledgeable people could tell me about different jobs in Geography and what you all do at said job/what are your experiences.

( I highly encourage anyone who replies to give as much info as possible I will appreciate everything you have to say)

There is a website where I can search for city suffix and prefix, the website has a dark overlay and the points were blue I suppose. For example if I wanted to search for rivers place names with "Mae" in Thailand it was able to display it on a little map. But german citiy names ending on like -stedt or whatever was possible. I think there was a heat map too.

Hopefully someone knows the website.

Around the world glaciers are retreating or disappearing entirely almost everywhere, with the notable exception of the glaciers in the Karakoram Range, most of which are either holding steady or actively growing.

The so-called Karakoram Anomaly has been the subject of intense study with in-depth studies appearing in scientific journals.

Lake Providence, Louisiana is an oxbow about six miles long in an abandoned bed of the Mississippi. The river took the town more than once, and each time the people moved, so today's town is on its third site.

In 1944 geologist Harold Fisk put out 15 maps for the Army Corps of Engineers showing every old course of the lower Mississippi he could find, from Cape Girardeau, Missouri, down to Donaldsonville, Louisiana. He and his team spent three years on it. They worked from deep borings drilled by the oil industry, engineering maps and fieldwork with Richard Russell, and the goal was to work out how the whole valley formed and how the river got to its 1944 course.

In the lidar the lake is the curved band from the top left toward the right, and the town's street grid is on its south bank in the lower right. The field lines on the left bend with the old channel. My own render of the lidar. Fisk's maps squeeze thousands of years of channel shifts into one picture.

Hopefully I wrote this correctly and its understandable, if not let me know.

For example, people point out Hawaii as an example of why states don't need DST. However, they have basically 12-ish hours of sunlight throughout the year. Alaska has 19 hours of sunlight near Anchorage in the summer and 5 hours in the winter. I would say for both of those the time change does not really seem needed.

Compare that to Minneapolis, Minnesota where it's 16 hours in the summer and 8 in the winter. So an argument for the time change in Minneapolis, Minnesota has a better argument.

When I have asked other people about where the time change makes sense. The answer I usually got from Denver, Colorado in the south to Saskatoon, Saskatchewan to the north.

Was geomapping from the northeast of Alpine, then, saw this.

I really couldn't think of a better place to ask this question as my searching skills are failing me. I'm hoping someone can help me figure out what this place might be called today/now. if question not allowed, please delete it.

for context, I've been digging into my family geneology/ancestry and I have my great great grandfathers marriage certificate from 1894. on it, it says his birthplace is the Mackenzie River District. and was born around 1871-ish

This would be in Manitoba, Canada, or the area referred to might have been called north west territory back then (I'm uncertain)... probably old hudson's bay company land (which was huge). and/ or might be a old First nation's reservation. if you need more details, I'll provide what I can

thank you in advance

I personally think you will see many empires like Ethiopia, where lots of smaller states and tribes will be gobbled up by a more powerful one. I don't think these hundreds of African states would survive to the present day

I’m on a cruise. We left Hong Kong around 10 pm and are heading southeast. It is now about midnight. To the north there is a blue glow on the horizon where there is only ocean. Do you know what could be causing it? I’m attaching a screenshot of where we are and a picture of the glow (in the comments).

A bit North of Dunedin, New Zealand is a stretch of coastline with a number of sea caves, one of which is the longest sea cave in the world, Matainaka Cave.

Matanaika Cave, next to Matanaka Beach, makes it confusing as the Kiwis seem uninterested in deciding whether the place name should have an “i” in it, or not.

At the other end of the beach is the Huriawa Peninsula, site of a Māori pā, or fortified villlage, where chief Te Wera and his people once withstood a six-month siege.

This island between Copenhagen and malmö only has a small settlement despite having two big cities on its surroundings. Why is this the case?

the kamchatka peninsula in east russia looks absolutely incredible for trekking. however, it is relatively geographically inaccessible to reach (expensive). any recommendations for somewhere that has everything in between volcanoes and meadows and glaciers, outside of russia?

thank you!!

Hello geology and geography enthusiasts,

Positioned between the colliding Arabian and Eurasian plates, the Anatolian peninsula exhibits complex tectonic deformation. This unique geographical positioning results in frequent seismic activity along regional fault zones.

Key geographical features driving regional seismicity include:

* Extensional Tectonics: Western Anatolian graben systems creating distinct valley structures.

* Strike-Slip Fault Systems: Major continental transform boundaries spanning hundreds of kilometers.

Sharing this overview for anyone interested in regional physical geography and active tectonics!
