Spatter cone collapse at the MLK vent

(May 2, 2005, 02:30:28 to 07:30:37)

The spatter cone collapse described in the movie below was also recorded by a time-lapse camera on the west flank of the Pu‘u ‘Ō‘ō cone. This camera was located about 70 meters from the MLK vent and recorded two pulses of lava effusion from the vent before collapse. The first, and larger, pulse of effusion was abruptly terminated by a large spatter burst that threw small gobs of spatter at least as far as the time-lapse camera.

Spatter cone collapse at the MLK vent

(May 2, 2005, 05:30:04 to 07:30:02)

During spring 2005, activity at the MLK vent, on the southwestern flank of the Pu‘u ‘Ō‘ō cone, changed from a period of construction to one of destruction. This was highlighted by the collapse of the main MLK spatter cone. The drain-back of lava beneath the spatter cone, following lava extrusion, apparently removed support of the overlying rock. Slight subsidence of the ground surface to the left of the cone can be seen occurring for a few minutes before the cone fell into the resultant cavity, presumably as lava drained away beneath the surface. The extrusion and collapse were also captured by a second time-lapse camera on the west side of Pu‘u ‘Ō‘ō (out of sight to the right from this view; see movie above). T

he images that make up this movie were acquired by a time-lapse camera positioned on the south flank of the Pu‘u ‘Ō‘ō cone, about 70 meters from the MLK vent.
