CGPS, borehole strain and tilt data - 24 December 2018 eruptive intrusion Etna volcano

On the early morning of 24 December 2018, after two months of Strombolian activity, Mt Etna was suddenly penetrated by a violent dyke intrusion that opened an eruptive fissure and continued to propagate southward for more than ten hours.<br>In this collection are included raw CGPS data from 24 to 25 December 2018 (Zip archive). Moreover, borehole strain data are included for the 24 December (positive variation = compression; negative variation = dilatation). Finally, borehole tilt data (biaxial) for the 24 December are also included (negative variation = uplift).
