Gas drilling has similarities with fracking, also causing shallow earthquakes.
This animation tries to show the quakes in Groningen via two ways: visually (red dots). The bigger the quake, the bigger the dot. And via sound: every beep represents a quake and the higher the beep, the heavier the quake.
IF a quake is above 3.4 a hotel bell rings, and also this will be noted in the time line.
On May 29, 1959 the NAM (= Shell and ExxonMobil) discovered the first Groningen gas in Kolham (Slochteren, the Netherlands / Holland). The Groningen field covers an area of approximately 900 km2, lies at a depth of 3,000 m and the thickness of the gas-containing layer is about 100 meters. Here you will find information about the earthquakes in Groningen . Since about 2012 the earthquakes caused by the gas exploitation increase in number and strength. The epicenter of all shocks is at about Loppersum and Huizinge. The expectation is that the quakes will get stronger.
The data are almost 'realtime'.

Gas drilling in Groningen gas field, the Netherlands
causing shallow & destructive earthquakes – realtime data – v2
Gas drilling is somewhat similar to fracking. Spoiler: In 2012, the shit really hits the fan…
Van der Sluis (geographer): ‘Gas extraction could result in quakes.’
Royal Netherlands Meteorological Institute (KNMI): ‘That wasn’t a quake, that was a plane breaking through the sound barrier.’
Attention: Some quakes are audible but not visible on the map.
‘In theory, gas extraction could cause quakes’ says Shell-ExxonMobil (= ‘NAM’).
‘Quakes up to 3.0 on the Richter scale are possible’ (MIT).
As early as 1991 houses started to collapse (discovered by Dutch radio program Argos, 2013).
Expert panel: ‘Sometimes, earthquakes are the result of gas extraction.’
Van der Sluis (geographer): ‘Shell-ExxonMobil is stalling.’
Earthquake at Roswinkel, M 3.4 / 3 km depth, very shallow.
Shell + ExxonMobil = NAM (‘Nederlandse Aardolie Maatschappij’).
‘Quakes probably caused by gas extraction’ (KNMI, Royal Netherlands Meteorological Institute).
Earthquake at Alkmaar, M 3.5.
KNMI, Royal Netherlands Meteorological Institute: ‘The relation between gas extraction and earthquakes is not coincidental.’
Earthquake M 3.5 / 3 km, triangle Middelstum, Stedum, Westeremden.
NOS (Dutch public broadcaster): ‘Perhaps it is just the frost causing this?’
‘Last year, the amount of gas sold abroad reached a record high.’ (NOS, Dutch public broadcaster).
Houses in Groningen damaged as a result of earthquake.
Again, Groningen is hit by a severe quake (Huizinge, M 3.6 / 3 km depth, very shallow).
Researchers: ‘Earthquakes stronger when more gas is extracted’. Shell-ExxonMobil: ‘Acceptable risk.’
‘Annual risk of earthquakes > M 3.9 is 7%. Advice: rapid reduction.’
Quake North of Groningen, M 2.8, 3 km depth, very shallow.
In 2013, ExxonMobil and Shell extracted twice the amount of gas from the ground than they agreed they would.
First earthquake close to the city of Groningen (200,000 inhabitants).
At least 1350 monuments are damaged.
100.000 house owners report damage.
