This project visualizes and analyzes 2.2 million earthquake records from the USGS dataset (1998–2025)

total generated data set is 144mb,

number of tiles that has smaller size than 100bytes is : 321796

number of tiles that has size between 100b, 1kb is : 13693

number of tiles that has size between 1kb, 5kb is : 8486

number of tiles that has size between 5kb, 50kb is : 5275

number of tiles that has bigger size than 50kb is : 279

empty tiles occupies 32 byte each and avg size for non empty tiles is ~4kb

Added the missing OSM attribution

You are right, it's my mistake

I don't have the exact size comparison between this approach vs PNG compression, but i guess the difference would be similar to the difference between DEFLATE vs brotli.

I'm curious about what you just asked of me though, i will make the actual measurements, and will update this page with the results when i got time.

just summing the selection area around the cursor

I've tried this software and it is super practical, it outputs a nice h264 encoded mp4 file. Configuring video FPS (currently defaults to 15) and having an option 'correspond to device pixel ratio' would be nice though.
