Occasional incandescence and flames were observed in webcams images from all three eruptive vents (S, W, and N) at Halema`uma`u Crater. On 10 September overflows were less frequent, slower, shorter in duration (less than 10 minutes), not fed by a dome fountain, and did not travel as far from the N vent. Overflows during the morning of 11 September were more vigorous and lasted longer than 10 minutes. Several of these were fed by dome fountains that were 5-10 m tall. They also traveled farther from the N vent compared to those from the 10th.\nThere were 104 lava overflows from the N vent during 7-12 September, with the last one starting at 0727 on 12 September. Occasional spattering and flames were observed from the W vent and less frequently from the S vent; more energetic spatter and large flames were noted during drainback events. Each overflow during 11-12 September averaged about 20 minutes, separated by periods of about 10-15 minutes. The size and vigor of the dome fountains in the N vent gradually doubled in size to 10-15 m high on 12 September.\nIntermittent spatter bursts were visible at the N vent during the early morning of 13 September and increased in intensity throughout the day. Around noon, the bursts began depositing spatter that started to build a small cone on the rim of the N vent. During the afternoon, effusive activity began to cool within the upper regions of the conduit. There were distinct Strombolian eruptions reported throughout the night, characterized by large, individual spatter bursts.

The seismic network detected 41 seismic events associated with the movement of magmatic fluids, along with earthquakes indicating internal rock fracturing; no volcanic explosions occurred during the period. Gas, steam, and ash emissions periodically rose as high as 500 m above the summit and drifted less than 10 km E and SE. Moderate sulfur dioxide (SO?) emissions averaged 753 tons per day, and 6 thermal anomalies (each 3 MW or less) associated with the lava dome were identified. The Alert Level remained at Orange (the third level on a four-color scale) and the public was warned to stay outside of a 12 km radius from the summit.\nSource: Instituto Geofísico del Perú (IGP)", "categories": [], "feed": { "title": "Smithsonian / USGS Weekly Volcanic Activity Report", "url": "https://volcano.si.edu/reports_weekly.cfm", "feed_url": "https://volcano.si.edu/news/WeeklyVolcanoRSS.xml" } } }, "metadata": { "status": 200, "final_url": "https://volcano.si.edu/news/WeeklyVolcanoRSS.xml", "elapsed_ms": 117, "not_modified": false, "method": "rss20" }, "provenance": [ { "step": "rss", "version": "0.3.2" }, { "step": "diff", "version": "0.3.2", "args": { "namespace": "volcanoes", "only": [ "added" ], "emit_initial": true } } ] } }, "url": "https://volcano.si.edu/reports_weekly.cfm" }, { "id": "d1c99d79f11c9af5c1c9", "title": "Semeru (Indonesia) - Report for 10 September-16 September 2026 - Continuing Eruptive Activity", "content_text": "The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported that activity continued at Semeru during 10-16 September, with daily eruptive events recorded by the seismic network.
