Activity of Kadovar, Turrialba and last assessment of the Palu earthquake.

Activity on Kadovar in Papua New Guinea is relatively little documented by the observatories.

Since September, it seems to concern only the summit, no plume coming out of the coastal dome.

The Sentinel 2 images show white top degassing on September 12, and on September 22, more intense.

On the images of September 22, September 27, and October 10, it is found that the west side of the island, which had greened, is covered with ashes.

A notice of ash dispersal is issued on 28 September by VAAC Darwin.

On October 12, the plumes of ashes succeed one another, leaving a rosary of clouds towards the west, always coming from the summit.

Thermal anomalies are reported by Mirova on 14 and 15 October, respectively 17 and 22 MW.

It should be noted that the Rabaul volcano Observatory reports an increase in activity on 21 September, remaining high until 26 September; Gray and brown plumes are observed several hundred meters above the summit crater, drifting to the northwest. Incandescence is reported from the main crater, southeast costal vent and other areas.

Small amounts of ash fell on Blup Blup Island.

On October 1, a plume rises to 900 meters asl, drifting westward; and on October 3, a cloud of ash is observed by satellite, drifting westward at an altitude of 2,100 meters asl. (in GVP)

The Ovsicori reports an eruption on October 15 at 5:42 am at Turrialba, lasting a few minutes and accompanied by a plume of gas and ash rising to 1,000 meters above the crater.

The seismographs recorded another explosion signal at 6:16.

Subsequently, passive emissions at a hundred meters above the crater occurred.

The assessment of the Sulawesi / Palu earthquake of September 28 has been revised ... still on the rise, unfortunately.

As of 15 October, there are 2,100 dead, 4,612 seriously injured, 680 missing, and 78,994 displaced persons.
