Part of the mountain was simply vaporized:

The initial satellite images from Iran’s Fordow nuclear enrichment site reveal that a section of the mountain guarding the facility was entirely destroyed by US bunker buster bomb strikes on Saturday.

Visible signs of possible bomb entry and debris were evident following President Trump’s unexpected B-2 stealth bomber assault overnight, as depicted in images captured by Maxar Technologies.

The previously brown mountainside appeared gray in certain sections, with the area’s topography altered by the explosion of 14 30,000-pound Massive Ordinance Penetrator (MOP) bombs.

If you look closely, you can see holes in the ground where presumably the bombs burrowed their way in before fully detonating:

As many as 12 (reports vary) of these massive bombs were used, and you can see again in this picture right where they apparently went in:

Six missile entry points are clearly visible. Twelve GBU-57 bombs in total were dropped on this site. The entry points are right above the main centrifuge halls (not the entrances, as was earlier reported). pic.twitter.com/bQOD8JhYPH
