Bárðarbunga - all earthquakes

Continually updated maps

In this article, the most recent earthquakes at Bárðarbunga 2014 are given by maps that are updated more or less continuously (see terms and conditions below) as well as all earthquakes since the onset of these events. Each earthquake is represented by a circle. The size of the circle indicates the magnitude. The timing of each earthquake is colour coded, see the bar to the right of each map. The date and timing of each map is in the lower right hand corner (yyyymmdd 00:00).

The first two maps show today's earthquakes (counting hours since midnight). The third one shows all earthquakes since the onset of this seismic event (counting days). The fourth shows the earthquakes each day (via link) and a video (certain period).

Manually processed earthquakes since midnight:

The bar on the right represents hours since midnight and it gives a colour code indicative of the time passed. The dark blue colour implies today's first earthquakes (just after midnight). As the day goes on, the colour of newly added earthquakes changes and a picture of today's events builds up. Earthquakes that occur after 22:00 are red. At 24:00, the map is cleared. A new day begins.

Automatic recording of earthquakes since midnight:

The bar on the right represents hours since midnight and it gives a colour code indicative of the time passed. The dark blue colour implies today's first earthquakes (just after midnight). As the day goes on, the colour of newly added earthquakes changes and a picture of today's events builds up. Earthquakes that occur after 22:00 are red. At 24:00, the map is cleared. A new day begins.

Manually processed earthquakes since 16 August 2014:

The bar on the right is counting days since the onset of events, 16.09.2014, and it gives a colour code indicative of the time passed. The dark blue colour implies the oldest earthquakes whereas the red colour implies the youngest earthquakes. Enlarge. Slowly, a thorough picture builds up of these prolonged seismic events.

Maps which show the earthquakes of each day are available. The link opens another web page where a map for each day can be chosen from a list of dates. Click the button "keyra" below the dates‘ column in order to run this sequence of events in chronological order. With every passing day, a new map is added to the list.

Additionally, a video has been made of such sequence for a certain period, 16 August til 23 September 2014. The bar to the right implies the age of any earthquake counting hours from the date and time given in the video at any given moment (these obligatory explanations are not important unless pausing the video). The period is run twice in the video, first fast and then at half speed.

Very clearly, the run of the video shows how the intrusive dike stretches towards northeast and how the earthquakes, large and small, cluster around the caldera rims of Bárðarbunga. Minor activity is seen in Tungafellsjökull (a small ice cap to the west); more impressive is the fact how dispersed the activity is initially and how it then clusters towards north (Kistufell) for a short while, before concentrating in two separate areas: along the dike and around the caldera.

Terms and conditions

Earthquake locations presented on this site are from preliminary analysis of the seismicity recorded by the Icelandic Meteorological Office. That is, locations from the automatic analysis system, SIL and the small fraction of the data that has been reviewed by analysts from IMO‘s SIL monitoring group. People using these data in their publications do so at their own risk, as earthquake locations and magnitudes may change upon further analysis and review.

If the data are used in publications, they should be clearly referenced as: "Preliminary analysed data by the SIL seismic monitoring group of the Icelandic Meteorological Office." Date of delivery from the data bank must follow.

Further information on usage of data from IMO's web-site is given under pages about IMO.
