Flow field from the coastal plain up to TEB vent

A wide shot of the current flow field, from the coastal plain up to the TEB vent. The current flow is still split into an eastern and western lobe on the coastal plain, entering the ocean along the eastern lobe (lower right). The area is scattered with small breakouts, several of which show up nicely in light grey.

Breakouts remain active near Kalapana, with vigorous activity situated approximately 630 meters (0.4 miles) west of the end of the Kalapana access road. This breakout, just south of a partially burned kipuka, was cascading into a small depression on the flow field.

Looking down into the vent cavity of the Halema‘uma‘u Overlook vent. The black ring on the walls surrounding the lava pond is a high lava mark, outlining the height the lava rose during a recent rise/fall cycle.

The lava pond in the vent cavity of the Halema‘uma‘u Overlook vent during the rise phase of a rise/fall cycle. In this photo, the lava pond is 95 m (312 ft) below the floor of Halema‘uma‘u crater. When the pond level is high there is very little fume, allowing for unusually clear views.

After recovering from last week's DI event, the lava surface in the Halema‘uma‘u Overlook vent returned to about 80 m (260 ft) below the floor of Halema‘uma‘u Crater. The north/northwest rim of the vent (right side of photo) is still noticeably overhung, making future collapses very likely.

Aerial view of the perched lava lake in Pu‘u ‘Ō‘ō crater. Small fluctuations in the lava lake level lead to frequent overflows. These serve to build the levee around the lake even higher, amplifying the perched appearance.

View from just below the summit of Mauna Loa looking back down the Southwest Rift. The Sulfur Cone is the white area just above center frame. Pu‘u o Keokeo is the barely visible bump just above Sulfur Cone at the crest of the Southwest Rift.
