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 Bogoslof
AVO reported that photos taken by a pilot on 10 January showed Bogoslof covered with dark gray ash, and a roughly 300-m-diameter submarine explosion crater on the E side of the island. Unrest continued during 11-17 January. Two short-lived explosions (five to six minutes long) were seismically detected at 1123 and 1230 on 12 January and observed by pilots. The estimated altitudes of the first and second plumes were 5.5 and 4.4 km (18,000 and 14,500 ft) a.s.l., respectively. Seismicity again increased at 2126 on 14 January and remained elevated. Six explosive events were detected between 2216 on 14 January and 0350 on 15 January. No volcanic clouds were identified in satellite data, although one lightning strike was recorded at 2232 on 14 January. Increased seismicity on 17 January indicated minor explosive activity; steam plumes with minor amounts of ash rose no higher than 4.6 km (15,000 ft) a.s.l. The Aviation Color Code remained at Orange and the Volcano Alert Level remained at Watch.

Report for Sabancaya
Based mostly on webcam views, the Buenos Aires VAAC reported that sporadic gas-and-ash puffs rose from Sabancaya during 11-14 and 16-17 January. Partial satellite views on 13 January revealed an ash plume at an altitude of 7.6 km (25,000 ft) a.s.l. On 16 January a pilot observed an ash plume that had risen to an altitude of 8.2 km (25,000 ft) a.s.l., though meteorological cloud cover prevented satellite and webcam confirmation.

Report for Colima
Based on webcam and satellite images, and the Mexico City MWO, the Washington VAAC reported that during 11-17 January ash plumes from Colima rose to altitudes of 4.1-6.4 km (15,000-24,000 ft) a.s.l. and drifted in multiple directions.
Source: Washington Volcanic Ash Advisory Center (VAAC)
Report for Dukono
Based on analyses of satellite imagery, model data, and notices from PVMBG, the Darwin VAAC reported that during 11-17 January ash plumes from Dukono rose to an altitude of 2.1 km (7,000 ft) a.s.l. and drifted almost 300 km N, NE, E, and SE.
Source: Darwin Volcanic Ash Advisory Centre (VAAC)
Report for Kilauea
During 11-17 January HVO reported that the lava lake continued to rise and fall, circulate, and spatter in Kilauea’s Overlook vent. Webcams recorded incandescence from long-active sources within Pu'u 'O'o Crater and from a vent high on the NE flank of the cone. The 61G lava flow, originating from a vent on Pu'u 'O'o Crater's E flank, continued to enter the ocean at Kamokuna. Active surface flows near Pu'u 'O'o advanced ESE; one branch was 2.4 km from the vent on 12 January.
