Geomagnetic activity as reported by NOAA (http://www.swpc.noaa.gov/products/notifications-timeline)

Geomagnetic activity on course, sudden impulses due to solar activity. Event
4005166231 marked with orange line.


Geomagnetic activity detected by Kiruna Geophysical Institute (Sweden )  http://www.irf.se/maggraphs/puls.php

Composite picture: 2 days before earthquake on top, 1 day before on middle, earthquake
day on bottom, event 4005166231 marked with orange line. Weak PC1 pulsation at 14:00 two days before earthquake. Weak activity, connected to geomagnetic turbulence in progress.


Geomagnetic activity detected by  Sodankyla Geophysical Observatory (Finland) http://www.sgo.fi/Data/Pulsation/latestPulsation.php

As above for Kiruna: any unusual activity, weak ones are connected to geomagnetic turbulence in progress. Event 4005166231 marked with orange line.
