CLICK PHOTO TO WATCH MOVIE! This Quicktime movie shows the impressive spattering at the western margin of the lava lake at Halemaʻumaʻu. The continuous spattering is often punctuated by bursts which throw lava onto the ledge (left portion of image), and this accumulating lava is building a spatter rampart. If you focus on the right portion of the image, you can see the slow migration of the lava lake surface crust towards the spatter source, where lava sinks back into the magmatic system.

The lava lake at Kīlauea’s summit was about 65 m (215 ft) below the floor of Halemaʻumaʻu crater yesterday (March 16, 2012), with impressive spattering along its western edge. (Hawaiian Volcano Observatory, USGS)
The spatter from the lava lake was landing, in part, on the ledge adjacent to the lake, and then flowing away in a small channel toward the southern side of the vent where it was ponding and cooling. Notice the wrinkled crust on the surface of the lake. (Hawaiian Volcano Observatory, USGS).
The latest image from a temporary thermal camera looking down at the lava lake in Halema’uma’u Crater. The temperature scale is in degrees Celsius up to a maximum of 500 Celsius (932 Fahrenheit) for this camera model, and scales based on the maximum and minimum temperatures within the frame. Thick fume, image pixel size and other factors often result in image temperatures being lower than actual surface temperatures. (Hawaiian Volcano Observatory, USGS)
