Short term prediction of earthquake magnitude, time, and location is currently not possible. In some cases, however, documented observations have been retrospectively considered as precursory. Here we present seismicity transients starting approx.

- - The study demonstrated that real-time seismic monitoring helped manage induced earthquakes during the stimulation of a geothermal well near Helsinki, Finland, by tracking their rates and locations.
- - Over 49 days in 2018, researchers injected 18,160 m of water into deep crystalline rocks, using a network of 24 seismometers to gather data.
- - By adjusting pumping pressure and flow rates based on seismic data, the team successfully avoided a significant earthquake (magnitude 2.0), which was a critical limit set by local authorities.
A primary hurdle in observing small foreshocks is the detection-limit of most seismic networks, which is typically about magnitude M1-1.5. We show that a start-up test of a borehole-based seismic network with a much lower detection limit overcame this problem for an M4.

Our analysis focuses on a two-week period during which prominent downhole pressure fluctuations in the reservoir were accompanied by a leakage of CO2 and CH4 along the monitoring well equipped with an array of short-period borehole geophones. We applied state of the art seismological processing schemes to the continuous seismic waveform recordings.
