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 Sabancaya
A Technical and Scientific Committee for volcanic risk management of the Arequipa region is comprised of five groups including IGP's Observatorio Vulcanológico del Sur (OVS) and INGEMMET's Observatorio Vulcanológico (OVI) and have been monitoring Sabancaya since 2013. The committee reported that new ash-bearing explosions began on 6 November. The explosions, detected at 2126, 2127, and 2149, produced ash plumes that rose 1.5 km above the crater rim and drifted E.

The frequency of hybrid earthquakes increased noticeably in early October and in the hours prior to the 6 November explosions. Volcanic gas emissions had also increased significantly, with values as high as 7,173 tons/day on 23 October. The MIROVA system had detected a thermal anomaly at the volcano on 2 November.

During 6-13 November ash-and-gas emissions from explosions and from periods in between explosions rose as high as 3 km above the crater. An event at 1320 on 8 November generated a significant ash plume that rose 2.4 km above the crater rim with ash dispersing within a 5-km radius. During 9-10 November ash plumes rose as high as 2 km and drifted 30-35 km SE, E, and NE, producing ashfall in the villages of Valle del Colca to the NE. On 11 November an explosion generated an ash plume that rose 3 km and drifted 40 km E and NE. An ash plume from an explosion the next day rose 2 km and drifted 30 km NE.

Report for Fuego
INSIVUMEH reported that during 11-15 November explosions at Fuego generated ash plumes that rose as high as 1.3 km and drifted more than 15 km W and SW. Some explosions produced shock waves detected within a 10 km radius and also ejected incandescent material as high as 300 m. Minor avalanches were confined to the crater. Ashfall was reported in Morelia (9 km SW), Santa Sofía (12 km SW), Sangre de Cristo (8 km WSW), and Panimaché I and II (8 km SW).

Report for Kilauea
During 9-15 November HVO reported that the lava lake continued to rise and fall, circulate, and spatter in Kilauea’s Overlook vent; the lake level rose almost to the rim (Halema’uma’u floor) during 9-10 November. Webcams recorded incandescence from long-active sources within Pu'u 'O'o Crater. The 61G lava flow, originating from a vent on Pu'u 'O'o Crater's E flank, continued to enter the ocean near Kamokuna at the easternmost lava delta.

Report for Klyuchevskoy
On 8 November, KVERT reported that activity at Klyuchevskoy had decreased significantly and therefore the Aviation Color Code was lowered to Yellow. Lava effusion onto the flanks was last noted on 3 November; the next day the thermal anomaly was reduced. Ash plumes were last detected in satellite images during 3-4 November. Strombolian activity in the crater was also observed on those days. Strong gas-and-steam emissions continued.

Report for Reventador
During 9-15 November IG reported a high level of seismic activity including explosions, long-period earthquakes, harmonic tremor, and signals indicating emissions at Reventador; cloud cover sometimes prevented visual observations. Almost daily incandescent blocks were observed rolling as far as 1.6 km down the E, SE, and S flanks. Gas, water vapor, and ash plumes rose as high as 2 km and drifted W and NW.

Report for Santa Maria
On 9 November a 15-m-wide, 1-m-deep lahar triggered by rainfall descended the Cabello de Ángel drainage, a tributary of the Nimá I river drainage on Santa María’s S flank, carrying tree trunks and blocks up to 1 m in diameter. The lahar had a minor sulfur odor. During 12-15 November explosions from the Santiaguito lava-dome complex generated ash plumes that rose to 800 m above the complex and drifted SW. Ashfall was reported in areas downwind, including Monte Claro, San José, and la Quinta.
Source: Instituto Nacional de Sismologia, Vulcanologia, Meteorologia, e Hidrologia (INSIVUMEH)
Report for Sheveluch
KVERT reported that during 4-11 November lava-dome extrusion onto Sheveluch’s N flank was accompanied by strong fumarolic activity, dome incandescence, ash explosions with ash plumes as high as 6 km (19,700 ft) a.s.l., and hot avalanches. Satellite images showed a daily thermal anomaly over the dome. According to video and satellite data, ash plumes drifted as far as 143 km E during 3-4 November. The Aviation Color Code remained at Orange.
