πŸ”οΈProbably you have seen this breathtaking video of an avalanche. 😲 Everyone survived.

Where was it shot? πŸ“

Let’s do some #GeoLocation 🌍! πŸ§΅πŸ‘‡ 1/…

#OSINT πŸ”Ž
#Verification πŸŽ₯
#HowToOSINT 🧐

There are NO street signs, logos, number plates, trees or any other visual indications 🫀... except πŸ”οΈπŸ”οΈ.

This part of #GEOINT is new to me. 🀫

I used a mountain range only once for a fact check of migrants arriving in the Balearic Islands πŸ‘‡: knack.be/factcheck/fact… 2/…
πŸ₯³Luckily a great TUTORIAL was released by Eyran Millis (@Istihbarat1800L) recently: linkedin.com/posts/eyran-mi… (as seen on Week in #OSINT by @Sector035)

With only this pdf-cocument πŸ“„ I decided to give it a try. 3/…
@Istihbarat1800L @Sector035 As always, I looked for the oldest version of the video first. ⏳

I found it on the Instagram page of the person who filmed it: instagram.com/harryshimmin/

In another post he publisched a video "documenting where I was which I made about 30 mins after the avalanche" πŸŸͺ. 4/…
@Istihbarat1800L @Sector035 He mentions he was in the Tian Shan mountains in Kyrgyzystan, but this is a HUGE area...

Luckily, that second video contains more mountains and a striking lake. πŸ‘€

Finding this lake would be easier than finding some very similar mountains in the avalanche video. πŸ€”5/...
@Istihbarat1800L @Sector035 Over to Twitter.

Maybe someone has already geolocated this footage? πŸ™

Well, I found a very interesting analysis by @EtienneBerthie2 of this avalanche with a quick search. πŸ”Ž
@Istihbarat1800L @Sector035 @EtienneBerthie2 The tongue of the glacier collapsed entirely over almost 300 m. The volume loss is roughly 1. 5 millions m³. 😲

For this analysis πŸ›°οΈ images were used.

How did they know where to look? "Kyrgyz colleagues gave me the coordinates of the glacier". πŸŸ₯ 7/..

labo.obs-mip.fr/multitemp/kyrg…
@Istihbarat1800L @Sector035 @EtienneBerthie2 Seems like a very good source! πŸ‘†

Unfortunately these coordinates are not mentioned in the article. 😒

BUT I found a way around. πŸ‘‡8/...
@Istihbarat1800L @Sector035 @EtienneBerthie2 The analysis includes a link to a map πŸ—ΊοΈ of changes in the height of glaciers: maps.theia-land.fr/couches-cartog…

Online maps usually have the coordinates of the location in their URL❗️

Just look for some numbers and "lat" and "lng" (latitude and longitude) πŸŸ₯ in the URL. 9/...
@Istihbarat1800L @Sector035 @EtienneBerthie2 We enter these coordinates in the search bar of Google Earth Pro. πŸŸ₯

It does indeed show a glacier. πŸŸͺ

And we see a lake. 🟨10/...
@Istihbarat1800L @Sector035 @EtienneBerthie2 The shape of the lake 🟨 in the video on Instagram (right) corresponds to the lake in Google Earth (left). βœ…

We are getting closer. πŸŽ‰

Remember, we want to find the point of view (POV), not the location of the lake or the glacier.

Where was this guy standing? 11/...
@Istihbarat1800L @Sector035 @EtienneBerthie2 Over to a tool called Peak Visor (@PeakVisor_app): peakvisor.com

This is much more accurate than Google Earth when it comes to mountains.

We put the location πŸŸ₯at the same side of the lake. And now we have to compare the β›°οΈπŸ—»β›°οΈ! 12/...
@Istihbarat1800L @Sector035 @EtienneBerthie2 @PeakVisor_app You can import a photo in Peak Visor (the screenshot with the lake) πŸŸ₯, so you can make an overlay with the mountains in the tool.

You can adjust by using some arrows 🟩, until you have a good match with the skyline of the picture. 13/...
@Istihbarat1800L @Sector035 @EtienneBerthie2 @PeakVisor_app This is the closest I got: 41.948877356825875 77.83925934703564 πŸ‘‡

To quote Millis' tutorial: "it takes a lot of patience to play with the points to the nearest location" and "this is a long process and sometimes can be [...] exhausting, but one picture is worth millions!" 14/.
@Istihbarat1800L @Sector035 @EtienneBerthie2 @PeakVisor_app Now we can simply turn around and also match the mountains from the avalanche. 🀯1

#Geolocation? 🏁15/...
@Istihbarat1800L @Sector035 @EtienneBerthie2 @PeakVisor_app Another quote from Millis: "Sometimes the location will be found within half an hour to an hour and in some cases also lasted 3 months, it's all a matter of practice, training, and thinking outside the box and the element that I think is most important is knowing the area." 16/..
@Istihbarat1800L @Sector035 @EtienneBerthie2 @PeakVisor_app Just TRY it yourself. It's really fun and less difficult than I thought it would be. πŸ˜ƒ

I'll give you a challenge to start with!

This is a picture I took myself years ago. Also in #Kyrgyzystan. Can you find the spot? Good luck! (I don't have the grid myself. 🫣) 17/...
@Istihbarat1800L @Sector035 @EtienneBerthie2 @PeakVisor_app What have we learned? πŸ‘©β€πŸ«

1) To try something new in #OSINT all you need is a good TUTORIAL. Thanks a bunch @Istihbarat1800L πŸ™
2) Peak Visor is the best tool around to match up mountains. πŸ—»β›°οΈπŸ—»
3) #Geolocation can be done in non urban areas, but it's definetly harder.πŸ“πŸ˜“ 18/.
@Istihbarat1800L @Sector035 @EtienneBerthie2 @PeakVisor_app Did you learn something from this #OSINT for #FactChecking?

You come across a video in a language you don't understand. Annoying. 😠

Wouldn't it be great if you could watch that video with English subtitles? 😍

You can! With a little help from AI!

(got the idea from @matt0177 πŸ™) Image
@matt0177 First thing you have to do is install Whisper (this is software from #OpenAI, same guys from #ChatGPT).

It's FREE, but not so easy to install. I used this tutorial:

All info on Whisper here: github.com/openai/whisper 2/...
@matt0177 If you installed Whisper correctly, you download the video on your PC and go to the folder where the video is.

Now you type "cmd", to open command-line-interface. 3/... Image

@EuromaidanPress The exact location of the video is difficult to find due to the limited visual elements in the background. 😒

But it's admittedly plausible that the video was shot in Poland. How do we know this? πŸ‘‡2/...
@EuromaidanPress On the locomotive we read PKP Cargo 🟨, which is the largest rail freight carrier in Poland πŸ‡΅πŸ‡±.

We find a picture of a PKP-locomotive with the same serial number ST44-1232 πŸŸ₯.

The road sign in the video 🟩 corresponds to the Polish W9 sign for train signals. 3/...

"Three drunken Ukrainian supporters were arrested in Qatar. The reason? They made a Nazi salute and vandalised posters at the Al Bayt stadium by drawing a Hitler moustache on the World Cup mascot La'eeb. When arrested, they showed no resistance."

Source: @AlJazeera Really? πŸ€”2/ Image
@AlJazeera The video features Al Jazeera's official logo πŸ‘†, has high quality and looks professionally made.

Good question! Let's start with some basic Google... 2/...

So we come to an article on the Kazakh news site Ekspress.
