The Latest Hawaiian Volcano Observatory Update

The latest update from the Hawaiian Volcano Observatory:

This photo looks northeast and shows Puʻu ʻŌʻō crater. Recent activity has been focused around a few spatter cones on the crater floor.

At the far edge of the crater, a small lava pond has been active and has been the source of flows extending northeast of Puʻu ʻŌʻō. Those flows are visible at the top-center of the photo. Just below the horizon two small sources of smoke mark where the flow front is burning lichen and moss covering older ʻaʻā flows.

A closer look at the flow extending northeast of Puʻu ʻŌʻō. Puʻu ʻŌʻō cone is at the right edge of the photo, and view is towards the northeast.

In the foreground, two sources of fume mark the path of the lava tube supplying lava to the flow front. In the top-left, a few sources of smoke mark where the flow margin is burning moss and lichen on older flows. Today, the flow front was just over 4 km (2.5 miles) from the vent on Puʻu ʻŌʻō.

South winds permitted clear views into the south portion of the Overlook crater, which is often obscured by thick fume.

The bright orange area is the location where lava at the surface of the lake sinks back into the system, with spattering and degassing common in this area. A broad ledge of recently deposited lava occupies much of the south portion of the crater.

Spattering is common in the area where lava sinks back into the system, and this photo shows these processes are occurring in a small grotto.

In the right portion of the photo, the ledge occupying much of the south part of the Overlook crater is visible. Parallel lines along the front face of this ledge might appear at first glance to be layering within the ledge, but are actually thin deposits of lava that mark recent levels of the lava lake, much like bathtub rings.
