DESCRIPTION:With UK’s net-zero carbon emissions goal for 2050\, geotherm
 al energy has become a promising renewable energy source with its low carb
 on footprint. In 2020\, it stood for 4.5% of UK’s renewable energy\, and
  there are several geothermal projects planned for the near future. Howeve
 r\, one of the risks associated with geothermal production is induced seis
 micity. Although small microseismic events are natural at geothermal sites
 \, a few recent cases of larger earthquakes overseas have alarmed the publ
 ic\, caused damage\, and paused or halted the energy development. Thus\, a
 s UK is developing its geothermal sites\, it is important to analyse the f
 irst earthquakes available from each location to better understand how the
  regions respond to ground motions and how the earthquakes behave. \n\nUsi
 ng a local Raspberry Shakes seismic network\, we examined the induced eart
 hquakes from the United Downs geothermal site in Cornwall\, UK\, and found
  that the region experiences more high-frequency content than expected bas
 ed on relevant models. We also concluded that low-cost Raspberry Shakes ar
 e a suitable alternative for preliminary seismic hazard analysis in region
 s lacking seismic networks. Additionally\, we investigated the first induc
 ed earthquakes from the Helsinki\, Finland\, deep geothermal site to get a
  closer look at the rupture behaviour of the earthquakes\, identifying cle
 ar rupture directivity and complex behaviour similar to larger\, natural e
 arthquakes.
