Heat creates pressure as it creates EXPANSION. Heat on all sides of a methane gas
mixture that itself is burning will create PRESSURE from the sides that is as much a
container as the walls of a wheat elevator or the smooth walls of a piston engine.

Sparks occur in the atmosphere due to friction between moving air masses, the very thing
that causes lightning flashes. A large amount of methane gas wafting upward along with the
prevailing westerlies would stir the mix unduly as methane is LIGHTER than air and thus
would create an inordinate number of UPDRAFTS. This spark traveled along the wick of
methane leading back to the source.
Your explosion was caused NOT because a methane gas mixture was burning on this side
or that, or even top and sides of the cloud, but because it was a HUGE cloud of well mixed
methane and air, equivalent to all the natural gas being piped about in the US at any given
time, and the burn spread around this cloud or that, under and over and around, until a
particular pocket of well mixed methane and air had NO WHERE TO GO WITH ITS
HEAT since the burn was all around. Itself burning, the heat ramped the combustion up to
the explosion level.
