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 and averaging 16 reported volcanoes, this is not a comprehensive list of all eruptions this week, but rather a summary of activity that meet criteria discussed in the "Criteria and Disclaimers" section below.

Volcanic activity reported here is preliminary and subject to change. Carefully reviewed, detailed narratives over longer time periods are published as reports of the Bulletin of the Global Volcanism Network available through volcano profile pages.

 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 Manam
The Darwin VAAC reported that on 12 July an ash plume from Manam rose to an altitude of 3.7 km (12,000 ft) a.s.l. and drifted N, based on satellite data and weather models.
Source: Darwin Volcanic Ash Advisory Centre (VAAC)
Report for Shishaldin
AVO increased the Aviation Color Code for Shishaldin to Yellow and the Volcano Alert Level to Advisory on 12 July following several weeks of increasing seismicity and elevated temperatures in the summit crater identified in satellite images. In addition incandescence in the crater was visible during an overflight. Seismic tremor continued to be elevated at least through 16 July.

Report for Stromboli
INGV reported that the paroxysmal explosive sequence at Stromboli on 3 July changed the morphology of the crater terrace. The rim of the terrace facing the Sciara del Fuoco was removed, and the N1 and N2 vents in Area N (north crater area, NCA) had enlarged and merged into one. After the paroxysmal event explosive activity rapidly decreased, though it remained more intense than normal. The vents of Area C-S (South Central crater area) produced explosions regularly during 8-14 July, and fed lava flows that traveled about halfway down the Sciara del Fuoco. Material from the lava-flow fronts rolled all the way to the coastline. A new lava flow from Area N (north crater area, NCA) began at 1900 on 14 July.

Source: Japan Meteorological Agency (JMA)
Report for Asosan
JMA reported that sulfur dioxide emissions at Asosan’s Nakadake Crater reached a high value of 2,300 tons per day on 12 July. Very small events ejected sediment during 13-16 July. The Alert Level remained at 2 (on a scale of 1-5).
Source: Japan Meteorological Agency (JMA)
Report for Colima
Centro Universitario de Estudios e Investigaciones de Vulcanologia - Universidad de Colima reported that intermittent steam-and-gas emissions, mainly from the NE side of the crater, and two small explosions were recorded during 5-12 July. Five lahars descended the Montegrande ravine. An overflight on 9 July revealed that the diameter of the vent had slightly increased, likely caused by subsidence, and other areas of minor subsidence within the crater were noted. An area of collapsed material on the outer W wall was also identified. Temperatures inside the crater were 116 degrees Celsius, lower than the temperature of 250 degrees Celsius recorded in May. The temperatures in the fumarolic area decreased from 202 degrees Celsius in May to 169 degrees. A thermal camera located S of the volcano recorded thermal anomalies associated with fumarolic emissions. Weather conditions sometimes prevented observations of the crater.

CENAPRED reported that each day during 9-15 July there were 49-326 steam-and-gas emissions from Popocatépetl, some of which contained minor amounts of ash. As many as three explosions per day were recorded, though weather conditions often prevented visual characterization of ash emissions. An explosion at 1949 on 11 July generated an ash plume that rose 2.8 km above the crater rim. The Alert Level remained at Yellow, Phase Two (middle level on a three-color scale).
Source: Centro Nacional de Prevencion de Desastres (CENAPRED)
Report for Reventador
IG reported that during 10-16 July seismic data from Reventador’s network indicated a high level of seismic activity, including explosions, long-period earthquakes, harmonic tremor, and signals indicating emissions. Weather often prevented views of the summit area, although during clear conditions ash plumes were visible rising at least 600 m above the crater rim and drifting W and N. Blocks were observed rolling 500-600 m down the flanks on 10 and 16 July.
