Ventusky is a wonderful app, however, I think there's another data set that could be added, certainly another premium layer, but....seismic data. Ventusky provides satellite and and a fair amount of oceanographic data in so far as it relates to weather, there is a proven correlative link between seismic potentials/activity and weather. I'm not asking for seismic predictive models, because that's still difficult even for experts, but current activity within the last "X" hours, raw info about tremors, quakes, landslides/mudslides, etc. I think such a layer would be an informative additional layer of data.
