Smithsonian / USGS Weekly Volcanic Activity Report

Weekly Volcanic Activity Map

The Weekly Volcanic Activity Report is a cooperative project between the Smithsonian's Global Volcanism Program and the US Geological Survey's Volcano Hazards Program. Updated by 2300 UTC every Wednesday, notices of volcanic activity posted on these pages are preliminary and subject to change as events are studied in more detail.

This is not a comprehensive list of all of Earth's volcanoes erupting during the week, but rather a summary of activity that meet criteria discussed in detail in the "Criteria and Disclaimers" section. Carefully reviewed, detailed narratives on various volcanoes are published as reports of the Bulletin of the Global Volcanism Network.

 Criteria & Disclaimers

Criteria



The Weekly Volcanic Activity Report does not necessarily include all volcanic activity that occurred on Earth during the week. More than a dozen volcanoes globally have displayed more-or-less continuous eruptive activity for decades or longer, and such routine activity is typically not reported here. Moreover, Earth's sea-floor volcanism is seldom reported even though in theory it represents the single most prolific source of erupted material. The Weekly Volcanic Activity Report summarizes volcanic activity that meets one or more of the following criteria:

- A volcano observatory raises or lowers the alert level at the volcano.
- A volcanic ash advisory has been released by a volcanic ash advisory center (VAAC) stating that an ash cloud has been produced from the volcano.
- A verifiable news report of new activity or a change in activity at the volcano has been issued.
- Observers have reported a significant change in volcanic activity. Such activity can include, but is not restricted to, pyroclastic flows, lahars, lava flows, dome collapse, or increased unrest.

Volcanoes are included in the "New Activity/Unrest" section of the Weekly Volcanic Activity Report if the activity occurs after at least 3 months of quiescence. Once a volcano is included in the "New Activity/Unrest" section, updates will remain in that section unless the activity continues for more than 1 month without escalating, after which time updates will be listed in the "Continuing Activity" section. Volcanoes are also included in the "New Activity/Unrest" section if the volcano is undergoing a period of relatively high unrest, or increasing unrest. This is commonly equal to Alert Level Orange on a scale of Green, Yellow, Orange, Red, where Red is the highest alert. Or alert level 3 on a scale of 1-4 or 1-5.

It is important to note that volcanic activity meeting one or more of these criteria may occur during the week, but may not be included in the Weekly Volcanic Activity Report because we did not receive a report.

Disclaimers



1. The Weekly Volcanic Activity Report is intended to provide timely information about global volcanism on a weekly basis. Consequently, the report is generated rapidly by summarizing volcanic reports from various sources, with little time for fact checking. The accuracy of the Weekly Volcanic Activity Report is dependent upon the quality of the volcanic activity reports we receive. Reports published in the Bulletin of the Global Volcanism Network are monthly, and more carefully reviewed, although all of the volcanoes discussed in the Weekly Volcanic Activity Report are not necessarily reported in the Bulletin. Because of our emphasis on rapid reporting on the web we have avoided diacritical marks. Reports are updated on the Weekly Volcanic Activity Report web page as they are received, therefore information may be included regarding events that occurred before the current report period.

2. Rapidly developing events lead to coverage that is often fragmentary. Volcanoes, their eruptions, and their plumes and associated atmospheric effects are complex phenomena that may require months to years of data analysis in order to create a comprehensive summary and interpretation of events.

3. Preliminary accounts sometimes contain exaggerations and "false alarms," and accordingly, this report may include some events ultimately found to be erroneous or misleading.

4. Many news agencies do not archive the articles they post on the Internet, and therefore the links to some sources may not be active. To obtain information about the cited articles that are no longer available on the Internet contact the source.

Report for Etna
INGV reported that ash emissions from Etna’s New Southeast Crater (NSEC) occurred at 1251 and 1254 on 6 November and were quickly dispersed by the wind. During 6-7 November several phases of frequent explosions produced ash puffs visible during the daytime and ejected incandescent material from Strombolian activity was visible at night. On 8 November the explosions occurred at intervals of several hours, producing small ash plumes that rose a few hundred meters above the summit and drifted ENE.

A culminating phase of lava fountains, ash emissions, and lava flows began at 0500 on 11 November, after about 10 hours of gradually intensifying Strombolian activity. Weather conditions prevented visual observations, but a strong increase in the volcanic tremor amplitude was detected. The phase of maximum intensity lasted about 7.5 hours, ending around 1130; the cessation of lava fountaining was followed by a long series of powerful explosions that generated loud bangs heard mostly in the N sector of the volcano. Ash and lapilli fell in areas E and NE. A voluminous lava flow expanded S from the NSEC, and two smaller lava flows traveled ESE and NE. Vigorous Strombolian activity continued, with explosions at intervals of 1-2 minutes, which launched incandescent material as high as 150 m above the crater rim. At night during 11-12 November Strombolian activity ceased and the lava flows were no longer active.

Report for Sinabung
Based on information from the Jakarta Meteorological Watch Office, webcam data, wind data, and satellite images, the Darwin VAAC reported that on 6 November an ash plume from Sinabung rose to an altitude of 3 km (10,000 ft) a.s.l. The next day an ash plume rose to the same altitude but was not observed in satellite images due to meteorological cloud cover. According to webcam views an eruption on 8 November produced a low-level ash plume. The Jakarta Meteorological Watch Office, the webcam, and satellite data detecting sulfur dioxide indicated two explosions on 10 November. The first one, at 0720, generated an ash plume that rose to an altitude of 3.7 km (12,000 ft) a.s.l. The altitude of the second plume, from an explosion at 1600, was unknown. An ash plume on 11 November rose to an altitude of 3 km (10,000 ft) a.s.l. and drifted less than 20 km SW. The next day an ash plume rose to an altitude of 3.7 km (12,000 ft) a.s.l. and drifted almost 40 km NW.

According to a news article posted on 12 November, more than 5,000 people from seven villages had evacuated their homes in recent days. The article noted that the government had called for an evacuation of people living within a 3-km radius of Sinabung, but people outside of that zone had also been evacuating.

Report for Tungurahua
IG reported that activity at Tungurahua remained at moderate levels during 6-12 November. Although cloud cover sometimes prevented visual observations of the crater, ash plumes were observed on most days. An ash plume rose 1 km and drifted W on 7 November. The next day ashfall was reported in Runtún (6 km NNE), Pondoa (8 km N), and Baños (8 km N). On 9 November an ash plume rose 3 km and drifted W, and blocks rolled down the flanks. Ash fell in Choglontus (SW), Bilbao (W), and Cusúa (8 km NW). On 10 and 12 November ash plumes rose 1 km and drifted SW, and 1.5 km and drifted W, respectively. Ashfall was reported in El Manzano (8 km SW) on 12 November.

Report for Aira
The Tokyo VAAC reported that during 6-8 and 10-11 November, explosions from Sakura-jima generated plumes that rose to altitudes of 1.8-3 km (6,000-10,000 ft) a.s.l. and drifted N, NE, E, and SE. On 8 November a pilot observed an ash plume drifting at an altitude of 2.1 km (7,000 ft) a.s.l.

Report for Chirinkotan
SVERT reported that during 4-6 November a thermal anomaly over Chirinkotan was observed. Steam-and-gas emissions during 5-6 November drifted 55-100 km SE. The Aviation Color Code remained at Yellow.
Source: Sakhalin Volcanic Eruption Response Team (SVERT)
Report for Chirpoi
SVERT reported that a thermal anomaly from Snow, a volcano of Chirpoi, was detected in satellite images during 4-6 November. Weak steam-and-gas emissions were detected on 4 and 6 November. The Aviation Color Code remained at Yellow.
Source: Sakhalin Volcanic Eruption Response Team (SVERT)
Report for Copahue
OVDAS-SERNAGEOMIN reported that during 16-31 October the webcam installed 18 km SW of Copahue recorded steady fumarolic activity from Del Agrio Crater, which produced plumes that rose 1.8 km above the crater rim. On 28 October the plume changed color, suggesting ash content, and was accompanied by a small explosion recorded at 1252. The Alert Level remained at Yellow.
Source: Servicio Nacional de Geología y Minería (SERNAGEOMIN)
Report for Karymsky
KVERT reported that moderate seismic activity at Karymsky was detected during 1-8 November. Satellite images detected a daily bright thermal anomaly on the volcano, possibly indicating weak Vulcanian and Strombolian activity. Ash plumes drifted 184 km SE and E during 2-3 and 5-6 November. The Aviation Color Code remained at Orange.

Report for Kilauea
During 6-12 November HVO reported that the circulating lava lake occasionally rose and fell in the deep pit within Kilauea's Halema'uma'u Crater. The plume from the vent continued to deposit variable amounts of ash, spatter, and Pele's hair onto nearby areas. At Pu'u 'O'o Crater, glow emanated from spatter cones on the N and S portions of the crater floor. On 5 November a cone erupted a low fountain of lava which waned quickly; it was the first lava erupted in Pu'u 'O'o in several months.

The 6.4-km-long Kahauale’a 2 lava flow, fed by the NE spatter cone, was active with scattered break-out flows and burned the forest N of Pu'u 'O'o. On 7 November geologists confirmed that, after being active for more than two years and producing some memorable ocean entries, the Peace Day flow, to the SE of Pu'u 'O'o, was no longer active.

Report for Sheveluch
KVERT reported that during 1-8 November several strong explosions from Shiveluch generated ash plumes that rose to an maximum altitude of 7 km (24,600 ft) a.s.l. Ash plumes drifted more than 290 km SE. Viscous lava continued to effuse onto the N and NE flanks of the lava dome, accompanied by hot avalanches, incandescence, ash explosions, and fumarolic activity. A thermal anomaly was detected daily in satellite images. The Aviation Color Code remained at Orange.
