A slidely rocky problem

Heart Mountain Heart Mountain (Montana/Wyoming), it seems, went for a holiday once, covering 100km in about half an hour.

You’re welcome to your own opinion, but a mountain doing 200km/hr is not something I’d be particularly be interested in being around at the time.

Apparently, lava intrusions through vertical cracks (“dikes”) into a confined fluid-layer drove the move. Kind of like the whistle on a pressure-cooker — but scaled up a little & heated by lava, not a stove.

One of the scientists involved (Aharonov) reckons that the Canary Islands might one day do the same thing. Splash!
