This is truly great - thanks for posting!
The Wikipedia page says:
Seismic activity surrounding the Bárðarbunga volcano has been
gradually increasing since 2007 with a brief respite during the
eruption at Grímsvötn in 2011. Activity has now (2014) reached a level
similar to that just before the Grímsvötn eruption.
Is it possible to plot time series of average magnitude of the earthquakes since 2007? I tried but data seem to include just few last days:
DateListPlot[
Transpose[
{Normal[dataset[All, {"timestamp", "size"}]][[All, 1]],
Normal[dataset[All, {"timestamp", "size"}]][[All, 2]]}
],
PlotRange -> All]
Also - shouldn't Wolfram Alpha has all these data too somehow? I do not see this "gradually increasing since 2007"
