Excerpt:

As the frozen Antarctic landscape at the bottom of the world adjusts to an ever hotter planet, we keep finding more mysterious phenomena beneath and within the ice. Now, there are "ice quakes" to add to that list.

It wasn't all so long ago that earthquakes were thought to not exist on this unforgiving continent. Scientists know better now, and have just reported another tremulous anomaly: ice quakes that shake the frozen landscape… but only ever at night.

When darkness falls, for a 6-12 hour period during the evening, scientists investigating the behaviour of ice on the McMurdo Ice Shelf picked up these mysterious ice quake vibrations, thanks to seismometers planted across the shelf landscape.

"In these areas we would record tens, hundreds, up to thousands of these per night," says glaciologist Douglas MacAyeal from the University of Chicago.

It's MacAyeal's business to study how meltwater and melting processes are affecting the Antarctic region; while it might sound surprising, it's actually melting that's responsible for setting off this nightly cavalcade of quakes.

Wouldn't it be amazing if we discovered an ancient city buried under the ice?

Or, even more amazing an alien culture? OMG! Spaced Invaders?

LoL, it would be really awesome, all joking aside. But you know how we roll. We would bomb them to $#@! and take their resources.

Unless we are already working with them.
