SN4 SpaceX's test tank went boom. It was a mixture of methalox (methane + oxygen). When it exploded it caused a shock front, what was the speed of this explosion?

Do all shock-waves like that travel at Mach 1 and thus limited by the speed of sound in air? With projectiles/aircraft I know you can have an oblique shock and determine the mach number. But the explosion is not a projectile per say and is spherical and thus one cannot determine this from the video footage.

Is it possible that the explosion caused a shock wave exceeding the speed of sound and if so how could one determine it from video footage or other sensors?
