Visualization of the Week: Every meteorite strike mapped

Vizzuality and CartoDB co-founder Javier de la Torre created a heatmap of meteorite impacts and produced a how-to video of the map's creation.

The meteorite that struck Chelyabinsk, Russia, last week — the largest reported since 1908, when a meteor hit Tunguska, Siberia — prompted the Guardian’s Datablog team to pull together data from the Meteorological Society, identifying all known meteorite impacts on Earth, some dating back to 2300 B.C. The initial map the team created with the data seems to be down, but their map inspired Vizzuality and CartoDB co-founder Javier de la Torre to produce a heat map using the same data, which Datablog editor Simon Rogers also highlights at The Guardian.

The interactive map allows users to zoom in on specific impacts, which can be clicked to bring up additional data, including the meteorite’s mass, type and year of impact:

De la Torre put together a video of how he created the map using CartoDB as well, and told Carl Franzen at The Verge that he created the map in just 30 minutes.
