A pseudo-3D viewer for the
IRIS Earthquake Browser.

Drag mouse to rotate the scene.

The mouse wheel zooms you in and out.

The View menu allows toggling coastline and plates, re-orienting the scene, automatic rotation and more.

On a mobile device? Use View / Mobile Mode.

Rotation slow? Use View / Shading off and View / Hide coast.

Best performance is with recent Chrome, Safari, Firefox and Opera Next.

Too many earthquakes slows some browsers down.
Chrome, Safari and Opera Next are quite fast.
Firefox recent versions is pretty good.
Internet Explorer all versions is slow.

If browser is unresponsive, not shading quakes and not showing coastline (see View menu) speeds things up.
