Abstract
Anthropogenic earthquakes pose a rapidly increasing threat to society, infrastructure and the energy sector. Currently, neither the physics nor the expected hazard levels of induced seismicity are well understood. This cross-faculty PhD project will assess differences between induced and tectonic earthquakes in terms of source properties and ground motions. The aim is to exploit a better understanding of the mechanics and shaking for risk assessments of induced seismic hazard.

| Description | We analyse microseismic earthquakes to calculate characteristic physical measurements of the earthquake source, which can be used after and before operations to better inform hazard assessment. 1. Operators should take care to ensure that the recording equipment along a borehole does not show spurious frequencies, especially towards deeper stations. 2. Traditional models used to calculate the speed that size of an earthuqake may not be appropriate for microseismicity. |
