earth changes maybe a sinkhole?

yeah i was thinking this could have been the start of another sinkhole which are very commmon in this area. but the trees are bulging away from the hole which mean it has to be something trying to rise up. so it could be a new construction of a undergound miltary base as there was reports of a small earthquake. could be blasting. have to see if there are any more reports. also on the bad side it could be a new magma channel. i am open to any ideas?
