 Activity for the week of 8 March-14 March 2017

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 at volcanoes that meet criteria discussed in detail in the "Criteria and Disclaimers" section. Carefully reviewed, detailed reports on various volcanoes are published monthly in the Bulletin of the Global Volcanism Network.

Volcano index photo  Bezymianny  | Central Kamchatka (Russia)  | 55.972°N, 160.595°E  | Elevation 2882 m

KVERT reported that an explosive eruption at Bezymianny began at about 1330 on 9 March. Based on webcam observations, at 1454 an ash plume rose to altitudes of 6-7 km (20,000-23,000 ft) a.s.l. and drifted 20 km NE. The Aviation Color Code was raised to Orange (the second highest level on a four-color scale). About 30 minutes later, at 1523, an ash plume rose to altitudes of 7-8 km (23,000-26,200 ft) a.s.l. and drifted 60 km NW. KVERT raised the Aviation Color Code to Red. Satellite data showed a 14-km-wide ash plume drifting 112 km NW at an altitude of 7 km (23,000 ft) a.s.l. Later that day a 274-km-long ash plume identified in satellite images drifted NW at altitudes of 4-4.5 km (13,100-14,800 ft) a.s.l.; the majority of the leading part of the plume contained a significant amount of ash. A lava flow traveled down the NW part of the lava dome. The Aviation Color Code was lowered to Orange. Ash plumes drifted as far as 500 km NW.

Volcano index photo  Bogoslof  | Fox Islands (USA)  | 53.93°N, 168.03°W  | Elevation 150 m

AVO reported that an explosive event at Bogoslof began at about 2236 on 7 March, indicated in seismic, lightning, and infrasound data, and lasted about three hours. Though ash was not immediately visible in satellite data, AVO raised the Aviation Color Code (ACC) to Red and the Volcano Alert Level (VAL) to Warning. Later, satellite images showed a large ash cloud rising to an altitude of 10.7 km (35,000 ft) a.s.l. and drifting E. This event was the first detected eruptive activity since 19 February, and more than 1,000 lightning strokes related to the volcanic eruption cloud were detected during this event, by far the highest number observed to date. In addition the seismic levels were among the highest detected since the beginning of the eruption. Satellite images from 8 March showed that the W part of the island had grown significantly. The ACC was lowered to Orange and the VAL was lowered to Watch on 9 March.

Two earthquakes swarms were detected during 9-11 March; the first began at 1750 on 9 March and ended at 1400 on 10 March, and the second was detected from 1900 on 10 March to 0500 on 11 March. Mildly elevated surface temperatures were identified in satellite data during 10-11 March. A third swarm began at 0500 on 12 March. A short-duration event, from 1131 to 1143 on 13 March, produced a small ash cloud that rose to an altitude of 5.5 km (18,000 ft) a.s.l. and drifted SSW. AVO noted that after the event, the level of seismic activity declined and the repeating earthquakes, detected for much of the previous several days, stopped. Weakly elevated surface temperatures were observed in two satellite images from 13 March. A photograph taken by a pilot showed a low-level, billowy steam plume rising from the general area of the intra-island lake.

Volcano index photo  Fuego  | Guatemala  | 14.473°N, 90.88°W  | Elevation 3763 m

INSIVUMEH reported that six explosions and weak shockwaves were detected at Fuego on 9 March. Ash plumes rose 900 m and drifted S and SW. Ashfall was reported in Panimaché I and II (8 km SW), Morelia (9 km SW), and Santa Cecilia. Avalanches of material traveled towards the Santa Teresa (W), Trinidad (S), and Las Lajas (SE) drainages. The number and intensity of explosions increased on 10 March. Ash plumes rose as high as 2.7 km and drifted more than 10 km W and SW. Ash fell in areas downwind including Panimaché I and II, Morelia, Santa Sofía (12 km SW), Finca Palo Verde, Sangre de Cristo (8 km WSW), and San Pedro Yepocapa (8 km N). During 11-14 March explosions produced ash plumes that rose 0.5-1 km and drifted 8-12 km NW, W, and SW. Ash fell in multiple areas including Panimaché I and II, Morelia, and Santa Sofía. Incandescent material was ejected as high as 200 m above the crater rim.

Volcano index photo  Kilauea  | Hawaiian Islands (USA)  | 19.421°N, 155.287°W  | Elevation 1222 m

During 8-14 March 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, from a vent high on the NE flank of the cone, and from a small lava pond in a pit on the W side of the crater. The 61G lava flow, originating from a vent on Pu'u 'O'o Crater's E flank, continued to enter the ocean at Kamokuna. Surface lava flows were active on the coastal plain, and on and above the pali.

Volcano index photo  Nevados de Chillan  | Chile  | 36.868°S, 71.378°W  | Elevation 3180 m

OVDAS-SERNAGEOMIN reported that the number of phreatomagmatic explosions at Nevados de Chillán increased on 7 March, after a month and a half of no explosive activity. Explosions from the craters on the E side of Volcán Nuevo and the Volcán Arrau dome complex produced plumes that rose 300 m on 7 March, and then subsequently seismicity and surficial activity gradually increased. On 11 March there were eight explosions detected. Plumes rose as high as 500 m and incandescent material was ejected 500 m away from the craters. A series of eight explosions beginning at 0617 on 16 March generated ash plumes that rose 1.5 km and again ejected incandescent material. The Alert Level remained at Yellow, the middle level on a three-color scale, and the public was reminded not to approach the craters within a 3-km radius.

 News Feeds and Google Placemarks


The RSS (Really Simple Syndication) feed is identical to the Weekly Volcanic Activity Report minus some features including the header information (latitude and longitude and summit elevation), the Geologic Summary, and a link to the volcano's page from the Global Volcanism Program. Each volcano report includes a link from the volcano's name back to the more complete information in the Weekly Volcanic Activity Report on the Smithsonian website.




The CAP (Common Alerting Protocol) feeds are XML files specifically formatted for disaster management. They are similar in content to the RSS feed, but contain no active links.




A Google Earth network link for the Weekly Volcanic Activity Report can be loaded into the free Google Earth software, and in turn will load placemarks for volcanoes in the current weekly report. Placemark balloons include the volcano name, report date, report text, sources, and links back to the GVP volcano page for that volcano and to the complete Weekly Report for that week.

 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.

5. USGS Disclaimer Statement for this Website:

Information presented on this website is considered public information and may be distributed or copied. Use of appropriate byline/photo/image credit is requested.

RSS and CAP Feeds

An RSS (Really Simple Syndication) feed for the Weekly Volcanic Activity Report first made available on 5 March 2008 can be utilized with the aid of various free downloadable readers. The report content of the news feed is identical to the Weekly Volcanic Activity Report minus some features including the header information (latitude and longitude and summit elevation), the Geologic Summary, and a link to the volcano's page from the Global Volcanism Program. Each volcano report includes a link from the volcano's name back to the more complete information in the Weekly Volcanic Activity Report on the Smithsonian website. On 12 March 2009, GeoRSS tags were added so that the latitude and longitude for each volcano could be included with the feed.

At the end of each individual report is a list of the sources used. We would like to emphasize that the World Organization of Volcano Observatories (WOVO) website (http://www.wovo.org/) lists the regional volcano observatories that have the most authoritative data for many of these events.

CAP (Common Alerting Protocol) feeds are XML files specifically formatted for disaster management.


Google Earth Placemarks

A Google Earth network link for the Weekly Volcanic Activity Report was first made available on 1 April 2009. This file can be loaded into the free Google Earth software, and in turn will load placemarks for volcanoes in the current weekly report. Placemark balloons include the volcano name, report date, report text, sources, and links back to the GVP volcano page for that volcano and to the complete Weekly Report for that week.
