The large amount of rubble surrounding the sinkhole in the aerial images suggests overturning, though not like you'd see with an impactor, but rather--as several have noted--of the type that would be expected from the sudden expansion of subsurface gas. However, the ground-level video doesn't appear to match the aerial views, as the latter is almost completely devoid of the rubble displayed in the former. Too, the latter appears substantially larger than the former, telling me that either these are two separate things, or the ground level video was taken at a later date after the hole widened, causing much of the rubble-strewn perimeter to fall into it.
Interesting, anyway...
