Ap­prox­i­mately 70 earth­quakes oc­curred on the Bárðar­bunga caldera rim in the last 24 hours re­ports the Ice­land Met Of­fice this morn­ing. The strongest quakes were of the mag­ni­tude of 4.8 yes­ter­day at 13:21 and at 4.6 at 01:36. Seven earth­quakes al­to­gether ex­ceeded the mag­ni­tude of 4, and 15 earth­quakes were in the mag­ni­tude range of 3-3.9. Sub­si­dence of the caldera is con­tin­u­ous.

Ac­cord­ing to the Ice­land Met Of­fice, no sig­nif­i­cant changes are ob­served in the seis­mic ac­tiv­ity around the Bárðar­bunga vol­canic sys­tem.

Around 30 events have been de­tected in the north­ern part of the dyke in­tru­sion, be­tween north­ern Dyn­gju­jökull and the erup­tion site in Holuhraun. The strongest ones were both of the mag­ni­tude 1.4 yes­ter­day at 10:07 and 13:33.

An earth­quake of 3.0 oc­curred south­east of mount Herðubreið yes­ter­day af­ter­noon at 17:04 and around 10 smaller quakes fol­lowed. The re­gion around mount Herðubreið and Herðubreiðartögl has been mod­er­ately ac­tive in re­cent days. Al­though this ac­tiv­ity might be a re­sponse to in­creased stress due to the dyke in­tru­sion south-south­west, the re­gion has been fre­quently ac­tive in the past and a di­rekt link be­tween the in­tru­sion and the pre­sent ac­tiv­ity is not ob­vi­ous. No ac­tiv­ity was ob­served un­der Tung­nafell­sjökull.
