Global warming doubles glacial quakes

[Nihil]

> The number of glacial earthquakes, caused when rivers of ice lurch

...

> Seismologists at Harvard University and Columbia University predict more
> of such events, in which glaciers as big as Manhattan Island lurch
> unexpectedly, yielding tremors of up to magnitude 5.1 on the
> moment-magnitude scale, the modern equivalent of the Richter scale.

> that is sufficient to generate moderate seismic waves."

:wow:
