I hope you are not going to pay the price of trusting Al-Saudi goons.
They are in the arms of Israel. A well known fact, wonder why are you not aware of this?!!!
I have seen these videos and first thought the same as you.. but after looking up some types of conventional explosions, i was assured that is was not a tactical nuke.. and not by Usrael at all..
Nuclear explosion:
Blast produces an intense shock wave and high winds that create flying debris. It may collapse shelters and some fighting positions.
Thermal radiation causes burns and starts fires. The bright flash at the time of the explosion can cause a temporary loss of vision or permanent eye damage if you look at the explosion, especially at night.
Nuclear radiation can cause casualties and delay movements. It may last for days and cover large areas of terrain. It occurs in two stages: initial and residual.
Initial radiation is emitted directly from the fireball in the first minute after the explosion. It travels at the speed of light along straight lines and has high penetrating power.
Residual radiation lingers after the first minute. It comes from the radioactive material originally in a nuclear weapon or from material, such as soil and equipment, made radioactive by the nuclear explosion.
EMP is a massive surge of electrical power. It is created the instant a nuclear detonation occurs and is transmitted at the speed of light in all directions. It can damage solid-state components of electrical equipment (radios, radars, computers, vehicles) and weapon systems (TOW and Dragon). Equipment can be protected by disconnecting it from its power source and placing it in or behind some type of shielding material (armored vehicle or dirt wall) out of the line of sight to the burst. If no warning is received prior to a detonation, there is no effective means of protecting operating equipment.
==================================================
Most definitely not a nuke - Everyone associates mushroom clouds with nukes, but they are produced by conventional explosives also. The explosion creates very hot air that rises, when it meets the denser cold air above it, the hot air is pushed downward, forming the mushroom cap shape. If that was a nuke, even a small one, the camera man probably would have been killed by the impact blast. It was just a large conventional explosive..
I'm leaning towards a large bunker buster. Maybe 1,000 pounds..
