Half a century of the planet's volcanic eruptions and earthquakes have been visualised in an animated app.

It was created by the Smithsonian Global Volcanism Program, with data from the US Geological Survey.

The centrepiece is this click-and-play animation showing every eruption and earthquake for the last 50 years.
