The daytime view of 2025 eruptive fountaining episode 33 wasn’t as tall as it had been before sunrise, but I moved around to the SE side to get more of a broadside view of the spectacle before it fizzled out. Still, at least 100 cubic meters per second of lava chunks shot forth in a pulsating plume, slowly cooling into thousands of airborne and mostly incandescent rocks still near 2,000 degrees F, in this view shot forth from the South Vent. The lava pieces, some as big as cars, shot hundreds of feet through the air at an ideal, nearly 45-degree angle to produce a pyramid-shaped fountain plume. Some of the lighter stones, scoria, beads, and pebbles (tephra) blew off the top end toward the left, in the low-level northeasterlies that prevailed near and above the level of the surrounding crater rim. Rocks hitting the ground continually raised dust made of volcanic glass, some of which got caught up and lofted into the hot convective plume. What appears to be talus slopes in the background right, against the north rim of the crater, actually were tephra piles left over from several of the previous 32 fountaining episodes of this eruptive event since December 2024.
