Spattering is common in the summit lava lake, normally at one or more sites along the lake margin. A spattering area along the northeast lake margin on Friday, November 17, is shown here. The surface crust tends to flow into the spattering area, where it sinks. This migration can produce rips and tears of the lava lake crust as it approaches the chaotic spattering zone.
