There was no crater at the Murrah building in OK city, you may be thinking of the clearing efforts that involved the basement. The ANFO in the truck destroyed the front of the building and caused a collapse of the upper floors.
The NK explosion is more indicative of a projectile or something planted beneath the surface.
Yes, I do believe there was a crater and there were attempts to keep it from being published. That photo you just posted doesn’t show it because it is filled in from debris from the building.
If you examine this photo, you will see the blue tarp covering the crater.

Other than with speculative theories which are not supported by the majority of the engineering community (see Partin Report), it has been widely accepted that the trigger to the collapse of the Murrah Federal Building was the detonation of a homemade bomb contained in a rental truck which was parked in front of the nine-story office building on N.W. Fifth Street. The resulting crater from the blast was approximately 28 feet in diameter and 7 feet deep. This crater was measured to be only about 10 feet away from Column G20 of the Murrah Building. After conducting analysis, the BPAT found that the required energy which would result in a crater of equal magnitude would be equivalent to that of the detonation of approximately 4,000 lbs of trinitrotoluene (TNT) (Mlakar, 1998, p. 113). After additional investigation, it was determined that the rental truck had been loaded with an estimated 4,800 lbs of ammonium nitrate and fuel oil explosive, also known as ANFO (Delatte, 2009, p.157). The detonation of bomb of this magnitude produces a radially propagating air-blast wave. The BPAT calculated that resulting pressures on the nine-story portion of the Murrah Building due to this air-blast wave were a maximum of 10,000 psi at the area closest to the detonation and a minimum of 9 psi at the upper west corner of the structure
“...something planted beneath the surface.”..
Funny they NOK’s didn’t report it as a gas leak.

I'm tempted to describe what you are full of; instead, I'll be generous and say that you are misled by a "camouflage effect" on early aerial photos. You sound like the ignorant rantings of the kinds of wackos here on FR who just have to see some sort of conspiracy in everything that happens.
Check my FRProfile. One of the reasons that I, as a fact-driven scientist. became involved with the analysis of the MB collapse, was because I was fed up with all the wacko BS like yours. ("No crater", "Laser/plasma beam from space", "Cars shoved up beneath the pavement", "Thermobaric (FAE) bomb centered over the parking lot", etc., etc...)
Your fallacy has a very simple explanation. Here's a photo taken about two hours after the explosion:
The blast damaged an A/C "chiller" uphill from the crater, quickly filling it wih red, OK-mud-tinted water. And, the water surface was covered with floating debris -- mostly sheets of paper. Voila! -- an almost perfectly-camouflaged crater!
I spent the better part of a year -- focusing on that crater and determining its dimensions. Obviously, FBI SAIC, Danny Defenbaugh flatly lied, by stating that the crater was covered "to protect water-soluble evidence". The crater was covered by eight (8) sheets of plywood (figure out the maximum dimensions for yourself...). Yet, the FBI reported the crater diameter as 28 to 32 feet -- thereby vastly overstating the force and brisant range of the truck-borne explosion.
As you can see, I'm no "FBI stooge" -- but I will not tolerate the propagation of crap like, "There was no crater at the Murrah building in OK city..." -- when I spent years eliminating such garbage -- in order to come to the correct conclusions (which the FBI misreprsented).
