The darker stuff with white here and there is a combination of magma and ground water flashed to steam. The brown stuff is more a combination of high velocity gas and steam smashing through anything in its way.

Today it has settled down in the usual lava fountain at one big vent, a few little vents issuing splats now and then.

Not a volcanologist. If one turns up, I'll let him/her use big words like "phreatomagmatic." But this is basically what's going on. The pops and occasional booms are satisfying, too.
