Derailment and fire of Canadian National crude oil train nea Gogama, ON

For sure this is my first post about Landsat imagery, and it won't be the last. This post show how landsat images can be used to monitor naturals disasters as well as a simple train deraillement.

The left image below is the result of Landsat 8 754 bands combination of the accident area on 16 February 2015 and even with a medium 30m pixel resolution, it's amazing what Landsat 8 can show. We can cleary see a red spot near the river and at least 11 pixels returns high saturation in the SWIR band (7) giving us an idea of how big the fire has been, even one full day after train deraillement on late 14 february.

A preliminary report from BST-TSB Canada speak about more than a million litres of petroleum product released in the area, and at least 19 tank cars breached.

On the right side, a before/after combination of landsat panchromatic bands shows the extent of the train fire and of the hypotetic oil spill (changes between before and after scenes are in red).
