Earthquakes and Eruptions

Bookmark and Share

This is a sample project from DataMarket's visualization gallery.

This visualization shows earthquake activity leading up to eruptions in Eyjafjallajökull in South-Iceland in March and April 2010.

Each bubble represents a measured earthquake and the size of the bubble represents its magnitude. Deeper earthquakes are represented with darker colrs while shallow earthquakes are brighter. An earthquake slowly fades out as time passes. Yellow stars indicate eruptions.

The earthquake data comes from the Icelandic Met Office. The base for the background map comes from Samsýn and Gísli Sverrisson helped with the map projection algorithms.
