It is not an explosion! NASA warned about asteroid earlier... They stated that a fragment of it can end civilization when it hits the earth. I actually thought the building beside my house has collapsed when this "thing" passed my roof earlier this morning, it forcefully opened the door I just closed!!! I am in Akure.

If it was an asteroid, did it sink into the ground

Yes it sank at eleyewo..near possibility church ... And the after effect was just as the googled image of asteroid effect.
