Russian forces continue to expand their sprawling lines of fortifications in Ukraine.

This update adds new sites to the interactive map and links each to satellite imagery. Check out the full map here: google.com/maps/d/edit?mi… (1/6)
A few important notes for this updated map of Russian field fortifications:

1) This map should not be seen as a complete list of Russia's fortifications.
2) The data does not distinguish between barriers, trenches, or other types of fortifications.

(2/6)
In eastern Ukraine, Russian forces added new layers to their defenses.

Many of these areas have been under Russian control since last summer, but fortifications were only built in the past few months. (3/6)
In Russian-occupied parts of southern Ukraine, Russian forces fortified intersections along key roads and built layers of defenses across open fields. (4/6)
Even inside Russian territory (Belgorod Oblast), fortifications were built a few miles from the border with Ukraine. (5/6)
The expansion of Russian fortifications in occupied Ukraine could impact coming counteroffensives.

I spoke with @shanvav about this and the scale of Russia's construction effort. (6/6) thedailybeast.com/satellite-phot…

Russian forces in Ukraine have built hundreds of kilometers of field fortifications over the past few months.

This interactive map shows where many of these sites are located and links each to satellite imagery. (1/4)

Important notes for this map of Russian field fortifications in Ukraine:

1) This map is not exhaustive and should not be seen as a complete map of Russia's fortifications.
2) The data does not distinguish between barriers, trenches, or other types of fortifications.

(2/4)
While many of Russia's fortifications in Ukraine have been constructed along the front line, others have been built around occupied cities.

For example, Russian forces fortified the city of Tokmak (Zaporizhzhia Oblast) with trenches and barriers. (3/4)

The recent sabotage of the Nord Stream pipelines highlights the threat posed by attacks on critical undersea infrastructure.

The submerged internet cables that keep the world connected could be a tempting target for rogue actors. (1/6) Image
A few severed cables would have far less impact on highly-connected nations than it could on smaller countries, which may rely on fewer points of connection. (2/6)
For example, in 2007, Vietnamese fishermen reeled in miles of internet cable.

This caused partial disruptions in the country's internet for more than a month. (3/6) computerworld.com/article/254166…

Thread on NASA's Fire Information for Resource Management System (FIRMS) and notable fires/thermal anomalies in Ukraine.

FIRMS offers near real-time data within hours of satellite observation (more here: earthdata.nasa.gov/earth-observat…). Image
Important notes for use in this context:

1) FIRMS data alone should never be considered proof of a clash or strike.
2) FIRMS cannot tell you what started a fire.
3) As always, poor weather can hinder detection.
The examples in this thread have been cross-referenced with map data to ensure that they were not obviously the product of industrial sources, such as a factory smokestack.
