Changes in groundwater trace element concentrations before seismic and volcanic activities in Iceland during 2010–2018
We analysed temporal variations of trace element concentrations in groundwater from a 101 m-deep borehole (HA01) in northern Iceland during 2010–2018 and compared them with seismic and volcanic events that occurred in the same period to identify potential hydrogeochemical precursors. An increase of...
