Llaima, Chile

SERNAGEOMIN reported that weak steam plumes were observed from Llaima’s main crater on 20 February. The ‘a’a lava flow that traveled 2.5 km during 2-13 February varied in width between 30-40 m and was 10 m thick. On 21 February small ash plumes rose from the E and SE flanks. Pyroclastic flows descended the E flank and possibly down the W flank. Sulfur dioxide plumes that rose from two craters within the main crater were visible during an overflight. On 22 February, a seismic signal pattern similar to that observed during a previous pyroclastic flow was noted. Ash-and-gas plumes rose from the E flank. On 23 February, an ash-and-gas plume rose from the SE flank.
