Eruptions

Centro Universitario de Estudios e Investigaciones de Vulcanologia – Universidad de Colima reported that intermittent steam-and-gas emissions, mainly from the NE side of the crater, and two small explosions were recorded during 5-12 July. Five lahars descended the Montegrande ravine. An overflight on 9 July revealed that the diameter of the vent had slightly increased, likely caused by subsidence, and other areas of minor subsidence within the crater were noted. An area of collapsed material on the outer W wall was also identified. Temperatures inside the crater were 116 degrees Celsius, lower than the temperature of 250 degrees Celsius recorded in May. The temperatures in the fumarolic area decreased from 202 degrees Celsius in May to 169 degrees. A thermal camera located S of the volcano recorded thermal anomalies associated with fumarolic emissions. Weather conditions sometimes prevented observations of the crater.

Volcanologists in Severo-Kurilsk (Paramushir Island), about 7 km E of Ebeko, observed explosions during 5-12 July that sent ash plumes up to 3.5 km (11,500 ft) a.s.l. The plumes drifted S. A thermal anomaly was visible in satellite images on 11 July. The Aviation Color Code remained at Orange (the second highest level on a four-color scale).

Based on satellite and wind model data, and notices from PVMBG, the Darwin VAAC reported that during 11-16 July ash plumes from Dukono rose to altitudes of 1.8-2.1 km (6,000-7,000 ft) a.s.l. and drifted N and NE. The Alert Level remained at 2 (on a scale of 1-4), and the public was warned to remain outside of the 2-km exclusion zone.

The Darwin VAAC reported that on 15 July an ash plume from Ibu rose to 2.1 km (7,000 ft) a.s.l. and drifted NE based on satellite images and weather models. The Alert Level remained at 2 (on a scale of 1-4), and the public was warned to stay at least 2 km away from the active crater, and 3.5 km away on the N side.
