Additional Reports

Reports are sometimes published that are not related to a Holocene volcano. These might include observations of a Pleistocene volcano, earthquake swarms, or floating pumice. Reports are also sometimes published in which the source of the activity is unknown or the report is determined to be false.

06/1990 (BGVN 15:06) Press reports of boiling water were apparently fabricated

The press reported that a submarine volcano was suspected to be the cause of an area of boiling water, roughly 500 m in radius, reported by a fishing boat 70 km W of Papudo (60 km NNW of Valparaíso). Upon investigation, it was determined that the initial report had never been verified and was apparently a fabricated message. Scientists onboard the Chilean naval vessal Carlos Arevalo found no evidence of a volcano in the area, a seismically active zone on the continental slope far from any known volcanism.
