The possible eruption reported from La Lorenza was mud volcano activity, as suspected. At 0800 on 21 October, ambient-temperature gray mud was ejected. At 0900, the petroleum gases (largely methane) emitted by the mud volcano ignited, producing a flame several hundred meters high, which lasted for several days. Contrary to press reports, no lava was emitted. People and cattle fled the area, but there were no deaths. Some livestock were injured.

Geologic Background. False or otherwise incorrect reports of volcanic activity.
