  The increasing rate in earth quakes in the Netherlands is attributed to the
enhanced depletion of Groningen natural gas, currently at a rate of 50 billion
m3 per year. We performed a model-independent analysis of the earth quake event
counts in KNMI data. We find an exponential growth since 2001 with a standard
deviation of 0.37% and a doubling time of 6.2 years, giving rise to one event
per day in 2025. A trend in the magnitude of the quakes is indiscernible. There
is no apparent sensisitivity to NAM pruduction of natural gas, which increased
linearly with a standard deviation of 9.4% over the last decade. We identify
the earth quakes with an avalanche triggered by a pressure drop, currently 50%
away from the equilibrium pressure at the depth of 3 km. Re-establishing
pressure equilibrium will proceed with an anticipated drop in soil surface up
to a few meters.
