Roundup of Global Volcanic Activity

Lokon volcano (North-Sulawesi, Indonesia): Small ash emissions along with white steam plumes have occurred again from the volcano recently. At the moment, there is no indications that they have been caused by new magma near the surface, and could be phreatic in nature, or due to disturbance of the hydrothermal system.

Slamet volcano (Central Java, Indonesia): eruption increases, powerful strombolian explosions. Activity at the volcano has increased and VSI raised the alert level to "siaga", 3 on a scale of 1-4. The mild strombolian activity which had been going on for months at the volcano has become more and more intense since the beginning of September. Some explosions in the past days have been strong enough to eject incandescent material to all over the summit cone of the volcano. In its latest report on 11 Sep, VSI mentions that 165 eruptions occurred on that day with ejection heights between 50-1500 m. BNPB, Indonesian's Civil Protection began preparing for a possible evacuation. According to them, 23,699 people are located within a radius of 5 to 6 km from the summit, and the area up to 4 km radius around the volcano has been declared an exclusion zone.

Kilauea volcano update: Lava slows, misses first homes for now. Between September 10 and 12, the June 27th flow advanced north-northeastward at an average rate of 250 m/day (820 ft/day). By the afternoon of September 12, the flow had advanced approximately 14.9 km (9.3 miles) straight-line distance from the vent, or to within 170 m (560 ft) of the boundary between the Wao Kele o Puna Forest Reserve and the northwest corner of Kaohe Homesteads. At the average rate of advancement of 250 m/day (820 ft/day) since September 10, we project that lava could flow from its current location into the northwest part of Kaohe Homesteads within a day, and to the Pāhoa Village Road (government road) in Pāhoa within 20 days if there are no major changes.
