SERNAGEOMIN reported that 10 low-magnitude volcano-tectonic earthquakes were detected at the Laguna del Maule Volcanic Complex during 16-31 October; seismicity was low in the region where a swarm had occurred in June. Satellite data showed no deformation, surface changes, gas emissions, or thermal anomalies. On 6 November the Alert Level was lowered to Green, the lowest level on a four-color scale. ONEMI cancelled the Yellow Alert for San Clemente, but declared a “Preventive Early Warning” ensuring continued surveillance of the area and coordination within the Civil Protection System.

SERNAGEOMIN reported that during 1-15 September inflation continued to be detected at the Laguna del Maule Volcanic Complex, although at a lower rate of 0.7 cm per month which is below the 2 cm per month average for this year. Seismicity in the S sector was low in both number and magnitude of events. The Alert Level remained at Yellow, the second lowest color on a four-color scale, as activity remained above baselines. ONEMI recommended restricted access within a radius of 2 km from the emission center.

SERNAGEOMIN reported that, although the number and magnitude of earthquakes had decreased during 20-30 June, seismicity at the Laguna del Maule Volcanic Complex continued to remain anomalously elevated at east through 7 July. The location of the activity remained within an area about 5 km in diameter, near the intersection of two faults near Las Nieblas, and corresponded to elevated levels of carbon dioxide emissions. The Alert Level remained at Yellow, the second lowest color on a four-color scale; ONEMI recommended restricted access within a radius of 2 km from the emission center.

SERNAGEOMIN’s Volcanological Observatory of the Southern Andes (OVDAS) of Chile and SEGEMAR’s Argentine Observatory of Volcanic Surveillance (OAVV) reported anomalous activity at Laguna del Maule Volcanic Complex. Elevated levels of carbon dioxide were detected in an area SW of the caldera lake, along the lower part of the Cabecera de Troncoso River, about 5 km from the lake’s shore. Carbon dioxide emissions were measured in February 2020 and notably elevated relative to March 2019 measurements. An impacted area possibly stretched as far as 500 m from the point representing the highest carbon dioxide emission rate; observers noted areas of discolored brown and orange soil aonlg with dead or emaciated animals.

Three swarms of volcano-tectonic (VT) earthquakes recorded in mid-June were mainly located in the Las Nieblas area, SW of the lake, at depths of 2-8 km. The first began at 0340 on 11 June and totaled at least 400 events. The second swarm began at 2338 on 12 June was characterized by 121 events, located 8.8 km W of the crater. The third swarm began at 2334 on 15 June and was characterized by 190 events located 10.4 km SW of the crater. All of the earthquakes were small magnitudes; the largest event was a local M 2.5. On 18 June the Alert Level was raised to Yellow, the second lowest color on a four-color scale; ONEMI recommended restricting access within a radius of 2 km from the emission center. Seismic activity continued to be recorded, though at lesser magnitudes.

Interferograms for Laguna del Maule, spanning the 1058-d time interval from 2007 February 12 to 2010 January 5 (P06). The panels include (a) observed phase values; (b) modelled phase values calculated from the final estimate of the parameters in the Okada dislocation model; (c) final residual phase values formed by subtracting final modelled values from observed phase values and (d) angular deviations for final estimate. One cycle of phase denotes 118.1 mm of range change. The ALOS orbit num- bers are 5602 and 21035. The altitude of ambiguity is 71.7 m. Unit vector [E,N,U] = [?0.6242, ?0.1851, 0.7590]. The incidence angle is 41? from ver- tical. Coordinates are easting and northing in kilometre using the Universal Transverse Mercator (zone 19) projection (Snyder 1982).

Photo Gallery

Pyroclastic cones and lava flows at the NW side of the Laguna del Maule volcanic center rise above the shore of the lake. This cluster of small stratovolcanoes, lava domes, and pyroclastic cones covers an area of 15 x 20 km within a Pleistocene caldera. Pleistocene and Holocene basaltic lava flows were erupted down the upper part of the Maule River valley and on all sides of the lake.
