There was a small bit about this in a newspaper today, apparently some experts think there is nothing special about the holes since such openings occur naturally all the time. No mention of methane bubbles in this article but they are at least pretty sure no meteorites have hit the ground lately.

Since I am positive reading Finnish will prove to be no difficulty, here is the original article ;-)
