The speed with which the fire in and around Fort McMurray is spreading has caught many off guard. As of Thursday afternoon it had consumed 85,000 hectares, up from 10,000 the day before.

The following GIF animation draws on satellite images provided by NASA Worldview captured over five days starting May 1. The red dots show fires and thermal anomalies and reveal just how far the fire was able to spread in a matter of days.
