-level readings. The results show a remarkable positive correlation
between water-level - a
proxy for discharge - and tremor intensity. This relationship is especially
apparent at fast-flowing, turbulent rivers. Similarly, an infrasound
array to the north of the Vatnajökull
ice-
cap shows diurnal variations in
acoustic signals that follow water-level
changes in a nearby glacial
