As one critical component towards carbon neutrality, clean energy is in dire need and has been actively developed in a number of countries. Benefiting from recent technical advances, shale gas has been actively developed in the past two decades with a boosted production volume. However, earthquakes that produced significant damages were found in different shale gas fields, raising significant concerns on how to balance the need for energy and mitigate risks of the induced earthquakes. The research results can be applied to earthquake monitoring in the shale gas field and mitigating earthquake risks.
