Iceland Met Office (IMO) reported that electrical conductivity levels in the Skálmur River, which drains from the Sandfellsjökull glacier on the E part of the Mýrdalsjökull ice cap that covers Katla, began to increase late on 26 July. Increased seismicity within the Katla caldera began to be detected around 0600 on 27 July. Unrest significantly increased at around 1100 and a jökulhlaup (a glacier-outburst flood) began in the river at around 1320. Reports indicated increased sulfur odors originating from Mýrdalsjökull, specifically in Hólaskjól. As a precaution, and to account for the possibility of volcanic unrest, at 1554 IMO raised the Aviation Color Code to Yellow, the second lowest level on a four-color scale. The flood water flowed over a 1-km-long section of Highway 1 (also known as the Ring Road), damaging the road in several places, and washing away part of the road located next to the Skálmur River bridge. According to a news article local authorities closed the road between Víkur and Kirkjubæjarklausturs and evacuated Sólheimajökull, an area near the glacier, and a service area the end of the Sólheimajökull road. The peak flow rate may have been as high as 1,000 cubic meters per second, making the jökulhlaup significantly larger than previous events in 2011 and 1950. Electrical conductivity levels indicated that the flooding had significantly decreased later that night, though the report noted that it may be days before the rivers return to seasonally normal levels. At 1031 on 29 July IMO lowered the Aviation Color Code to Green, noting that activity at Mýrdalsjökull had returned to normal levels, and water levels and electrical conductivity in the Skálmur River had decreased.

Jökulhlaup and elevated seismicity in 2011; filming sparks eruption fears
Microseismicity preceded and accompanied a jökulhlaup (a glacier-outburst flood) on 9 July 2011, as reported by the Iceland Met Office (IMO). The jökulhlaup escaped from under Mýrdalsjökull, the glacier that rests above Iceland's Katla volcano, its 10 x 14 km caldera, and environs (figure 4). IMO reported that microseismicity was registered near several ice cauldrons in the caldera for a few weeks prior to the event (figure 5). Peak harmonic tremor on 8 July coincided with rising water levels and increased water conductivity, as measured by the main flood gauge (figure 6; gauge is at red triangle on figure 4).
IMO reported that, on the same day, the main flood gauge was damaged when flood waters reached the instrument near midnight; another station, normally not in the water, started recording rising water around 0400 on 9 July, and the water level there rose 5 m within 5 minutes (figure 7). When the flood reached the main road approximately one hour later, the main bridge over the Múlakvísl river was destroyed and the road was closed (red triangle, figure 41).
According to the news source Morgunblaðið, 200 people were safely evacuated, and allowed to return to their homes by that afternoon. Morgunblaðið reported that analysis of the flood waters indicated that the flood was caused by geothermal water, but that a sub-glacial eruption at Katla could not be ruled out. IMO stated that the harmonic tremor declined on 9 July, following the jökulhlaup event. After observational flights, new cracks and cauldrons were reported in the ice of Mýrdalsjökull glacier (figure 8).
By 16 July, the National Commissioner of Icelandic Police in the Department of Civil Protection and Emergency Management reported that a new bridge had been built to replace the bridge destroyed in the jökulhlaup (figure 9).
August-December seismicity. IMO reported increased seismicity under Mýrdalsjökull in October (figure 10). They reported that 512 earthquakes occurred, with ~ 380 originating within the Katla caldera; a large portion (nearly 100) of those 512 earthquakes occurred on one day near the beginning of October (figure 11). The largest reported earthquake was M 4, with seven being larger than M 3. On 8 November, an M 3.2 earthquake that originated in the S most part of the caldera was felt by residents in the town of Vík.
Overall, following the July 2011 jökulhlaup event, seismicity has increased above background levels of the past year. The seismic peak is noticeable with respect to the number of earthquakes, their largest magnitudes, and the clustering under Katla (figures 10 and 11). The largest earthquakes were as large, or slightly larger, than the other earthquakes of M 3 or greater in earlier episodes of unrest (i.e., 1999 and 2002-2004, figure 10). The bulk of the 2011 seismic increase occurred over a shallow depth range (within 4 km of the surface, figure 12).
Television filming sparks eruption fears. The Iceland Review reported that, in the early morning of 9 December, the Icelandic emergency hotline received calls from residents reporting bright lights on the slopes of Mýrdalsjökull. Callers feared that an eruption had started at Katla. The bright lights had also been noticed on a webcam by observers in Norway, who also enquired if there was an eruption. When the glacial slopes were inspected to find the cause of the lights, it was discovered that they were from film crews for the HBO series "Game of Thrones", who were filming in the early morning to capture the desired light conditions.

Iceland Met Office (IMO) reported that an intense seismic swarm began at Katla at 0941 on 4 May with three earthquakes larger than M 4 occurring beneath the caldera within about 10 minutes. The Aviation Color Code was raised to Yellow, the second lowest level on a four-color scale. According to a news article the three largest events were magnitudes 4.8, 4.7, and 4.5, adjusted from previous estimates of 4.5, 4.3, and 4.2. The larger earthquakes were felt in Thórsmörk and by residents in areas S of Mýrdalsjökull glacier (the glacier that covers Katla). The intensity of the events decreased after noon, though smaller earthquakes continued. Seismicity had decreased significantly by the next day with only five events recorded during 0000-0915 on 5 May. In an update posted at 1140 the activity was described as normal, and the Aviation Color Code was lowered to Green. More than 40 earthquakes had been recorded during the previous day and no other data indicated significant changes or anomalies. It was noted that the magnitudes were unusually large and similar to events that last occurred in 2016.

On 29 July the Iceland Met Office (IMO) reported that a glacial outburst flood (jökulhlaup) in the Múlakvísl river, SE of Katla, had begun, and a M 3 earthquake along with a few smaller earthquakes were located in the N part of the caldera. Nearby seismic stations detected tremor possibly linked to the flood, though a subglacial volcanic component was not ruled out. The Aviation Color Code was raised to Yellow, the second lowest level on a four-color scale. The public was advised to stay away from the river; it was dark colored and had a sulfur odor. By 31 July the jökulhlaup had subsided with conductivity measurements and tremor slowly reaching normal levels. The Aviation Color Code was lowered to Green.

The Iceland Met Office (IMO) reported that an intense seismic swarm began at Katla on 29 September. The activity intensified again at 1202 on 30 September with tremor and several earthquakes M 3 or larger. The Aviation Color Code was raised to Yellow, the second highest level on a four-color scale. On 3 October IMO stated that the seismic swarm was the largest one in decades, though it appeared to be over. According to a news article from 3 October popular travel destinations near the glacier had been and remained closed to traffic.

The Iceland Met Office (IMO) reported that seismic activity within Katla's caldera had increased in mid-June and then began to decline. On 29 August two earthquakes of about M 4.5 occurred in the NE part of the caldera, the largest earthquakes detected at Katla since 1977. The ensuing swarm that same day produced over 100 earthquakes, the largest of which was M 3.3. Seismicity was low after the swarm had ended.
Throughout the summer, electrical conductivity levels in the Múlakvísl River, which drains from the E side of the Mýrdalsjökull glacier that covers Katla, had remained unusually high, reflecting a constant source of geothermal meltwater. There had also been frequent reports of a sulfur odor close to Múlakvísl; gas measurements near the source of Múlakvísl revealed unhealthy levels of hydrogen sulfide, also indicating high concentrations of geothermal fluids. IMO noted that the recent earthquake activity does not appear to have significantly affected conductivity levels in Múlakvísl.
IMO stated that summertime increases in caldera seismicity are an almost annual occurrence at Katla, often associated with the drainage of geothermal meltwater causing minor floods in glacial rivers from Mýrdalsjökull.

The Iceland Met Office reported increased seismic activity within Katla's caldera. Unrest was first noted in July, when a short-lived glacial flood burst from the Myrdalsjökull glacier that covers Katla occurred in connection with increased seismicity. Since then, several hundred micro-earthquakes had taken place within the area of the caldera. On 5 October an intense earthquake swarm was detected. Most of the earthquakes originated at 5 km depth; the largest one was approximately a M 3.7.

The Iceland Met Office and news sources reported that on 9 July a jökulhlaup from Myrdalsjökull, the ice sheet that covers Katla, originated from three ice cauldrons in the SE part of the caldera. During previous weeks microseismicity had been registered near several of the ice cauldrons. Around the time of peak harmonic tremor, in the early evening on 8 July, the Myrdalsjökull flood monitoring system indicated increased conduction. The water level reached the bridge around midnight and damaged the sensors. According to news articles, one new cauldron that had formed, along with cracks in the glacier around the cauldrons, may have been caused by a small eruption at Katla although no evidence of an eruption was observed. The jökulhlaup had destroyed a 128-m-long bridge and caused damage, resulting in the closing of part of the Ring Road. About 200 people were evacuated from the area but allowed to return home later that day. On 10 July the water had subsided and returned to normal levels.

Tremor in mid-July followed by a jökulhlaup and ice cauldron formation
In the early morning of 18 July, a small jökulhlaup (sudden glacier-outburst flood) lasting less than 24 hours, occurred in "Jökulsá á Sólheimasandi," one of the rivers draining from the Mýrdalsjökull icecap (figure 2) towards the S. Inspection of the icecap revealed that a new ice cauldron, ~2 km wide, and 50 m deep, had formed just above the origin of the Sólheimajökull outlet glacier. The jökulhlaup was preceded on 17 July by a 20-minute-long burst of modest volcanic tremor (reported by P. Einarsson). Intrusion of magma at a low level within the subglacial Katla volcano or even a small subglacial eruption may have occurred, possibly associated with pulse of CO2 which could have caused boiling in geothermal areas under the icecap.

From 18 July until mid-August, ten new ice cauldrons formed along the W, S, and E borders of the Mýrdalsjökull caldera (figure 3), signifying increased geothermal activity along a large part of the caldera rim. Changes on the icecap surface have been reported for some of the earlier eruptions of Katla, and the current activity could be a possible long-term precursor to a new eruption. A flight over the area on 9 September by Reynir Ragnarsson at Vík, revealed that the ice cauldrons did not develop much after mid-August.

This fissure eruption, the "Eldgjá Fires", produced one of the largest lava flows recorded, comparable to the volume of the nearby 1783 Laki (Skaftar) lava flow. The lava flow spread out in a broad lobe on the coastal plain, reaching the sea at Mydalssandur. The eruption produced an estimated 18 km3 of basaltic lava and 1.3 km3 of tephra (Thordarson et al., 2001). Including the amount deposited at sea, Larsen (2000) estimated a volume in excess of 4 km3. Conflicting descriptions of the estates of early settlers suggests that the eruption affected farms in the area (Larsen, 1979). Jonsson (1987) considered the Landbrotshraun portion of the flow to be much older; however, Larsen (2000) and Thordarson et al. (2001) considered this lobe to part of this eruption. The eruption was considered to have lasted until 940 CE by Oladottir et al. (2008). | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Catalogue of Icelandic Volcanoes (Link to Katla) | The Catalogue of Icelandic Volcanoes is an interactive, web-based tool, containing information on volcanic systems that belong to the active volcanic zones of Iceland. It is a collaboration of the Icelandic Meteorological Office (the state volcano observatory), the Institute of Earth Sciences at the University of Iceland, and the Civil Protection Department of the National Commissioner of the Iceland Police, with contributions from a large number of specialists in Iceland and elsewhere. This official publication is intended to serve as an accurate and up-to-date source of information about active volcanoes in Iceland and their characteristics. The Catalogue forms a part of an integrated volcanic risk assessment project in Iceland GOSVÁ (commenced in 2012), as well as being part of the effort of FUTUREVOLC (2012-2016) on establishing an Icelandic volcano supersite. |
Copernicus Browser | The Copernicus Browser replaced the Sentinel Hub Playground browser in 2023, to provide access to Earth observation archives from the Copernicus Data Space Ecosystem, the main distribution platform for data from the EU Copernicus missions. |
MIROVA | Middle InfraRed Observation of Volcanic Activity (MIROVA) is a near real time volcanic hot-spot detection system based on the analysis of MODIS (Moderate Resolution Imaging Spectroradiometer) data. In particular, MIROVA uses the Middle InfraRed Radiation (MIR), measured over target volcanoes, in order to detect, locate and measure the heat radiation sourced from volcanic activity. |
MODVOLC Thermal Alerts | Using infrared satellite Moderate Resolution Imaging Spectroradiometer (MODIS) data, scientists at the Hawai'i Institute of Geophysics and Planetology, University of Hawai'i, developed an automated system called MODVOLC to map thermal hot-spots in near real time. For each MODIS image, the algorithm automatically scans each 1 km pixel within it to check for high-temperature hot-spots. When one is found the date, time, location, and intensity are recorded. MODIS looks at every square km of the Earth every 48 hours, once during the day and once during the night, and the presence of two MODIS sensors in space allows at least four hot-spot observations every two days. Each day updated global maps are compiled to display the locations of all hot spots detected in the previous 24 hours. There is a drop-down list with volcano names which allow users to 'zoom-in' and examine the distribution of hot-spots at a variety of spatial scales. |
WOVOdat
Single Volcano View Temporal Evolution of Unrest Side by Side Volcanoes |
WOVOdat is a database of volcanic unrest; instrumentally and visually recorded changes in seismicity, ground deformation, gas emission, and other parameters from their normal baselines. It is sponsored by the World Organization of Volcano Observatories (WOVO) and presently hosted at the Earth Observatory of Singapore.
GVMID Data on Volcano Monitoring Infrastructure The Global Volcano Monitoring Infrastructure Database GVMID, is aimed at documenting and improving capabilities of volcano monitoring from the ground and space. GVMID should provide a snapshot and baseline view of the techniques and instrumentation that are in place at various volcanoes, which can be use by volcano observatories as reference to setup new monitoring system or improving networks at a specific volcano. These data will allow identification of what monitoring gaps exist, which can be then targeted by remote sensing infrastructure and future instrument deployments. |
Volcanic Hazard Maps | The IAVCEI Commission on Volcanic Hazards and Risk has a Volcanic Hazard Maps database designed to serve as a resource for hazard mappers (or other interested parties) to explore how common issues in hazard map development have been addressed at different volcanoes, in different countries, for different hazards, and for different intended audiences. In addition to the comprehensive, searchable Volcanic Hazard Maps Database, this website contains information about diversity of volcanic hazard maps, illustrated using examples from the database. This site is for educational purposes related to volcanic hazard maps. Hazard maps found on this website should not be used for emergency purposes. For the most recent, official hazard map for a particular volcano, please seek out the proper institutional authorities on the matter. |
IRIS seismic stations/networks | Incorporated Research Institutions for Seismology (IRIS) Data Services map showing the location of seismic stations from all available networks (permanent or temporary) within a radius of 0.18° (about 20 km at mid-latitudes) from the given location of Katla. Users can customize a variety of filters and options in the left panel. Note that if there are no stations are known the map will default to show the entire world with a "No data matched request" error notice. |
UNAVCO GPS/GNSS stations | Geodetic Data Services map from UNAVCO showing the location of GPS/GNSS stations from all available networks (permanent or temporary) within a radius of 20 km from the given location of Katla. Users can customize the data search based on station or network names, location, and time window. Requires Adobe Flash Player. |
DECADE Data | The DECADE portal, still in the developmental stage, serves as an example of the proposed interoperability between The Smithsonian Institution's Global Volcanism Program, the Mapping Gas Emissions (MaGa) Database, and the EarthChem Geochemical Portal. The Deep Earth Carbon Degassing (DECADE) initiative seeks to use new and established technologies to determine accurate global fluxes of volcanic CO2 to the atmosphere, but installing CO2 monitoring networks on 20 of the world's 150 most actively degassing volcanoes. The group uses related laboratory-based studies (direct gas sampling and analysis, melt inclusions) to provide new data for direct degassing of deep earth carbon to the atmosphere. |
Large Eruptions of Katla | Information about large Quaternary eruptions (VEI >= 4) is cataloged in the Large Magnitude Explosive Volcanic Eruptions (LaMEVE) database of the Volcano Global Risk Identification and Analysis Project (VOGRIPA). |
EarthChem | EarthChem develops and maintains databases, software, and services that support the preservation, discovery, access and analysis of geochemical data, and facilitate their integration with the broad array of other available earth science parameters. EarthChem is operated by a joint team of disciplinary scientists, data scientists, data managers and information technology developers who are part of the NSF-funded data facility Integrated Earth Data Applications (IEDA). IEDA is a collaborative effort of EarthChem and the Marine Geoscience Data System (MGDS). |
