Abstract
Abstract. Fluid injection into geological formations for energy
resource development frequently induces (micro)seismicity. Moderate- to
large-magnitude induced earthquakes may cause injuries and/or economic loss,
with the consequence of jeopardizing the operation and future development of
these geo-energy projects. To achieve an improved understanding of the
mechanisms of induced seismicity, develop forecasting tools and manage the
associated risks, it is necessary to carefully examine seismic data from
reported cases of induced seismicity and the parameters controlling them.
However, these data are challenging to gather together and are
time-consuming to collate as they come from different disciplines and
sources. Here, we present a publicly available, multi-physical database of
injection-induced seismicity (Kivi et al., 2022a;
https://doi.org/10.20350/digitalCSIC/14813), sourced from an extensive
review of published documents. Currently, it contains 158 datasets of
induced seismicity caused by various subsurface energy-related applications
worldwide. Each dataset covers a wide range of variables, delineating
general site information, host rock properties, in situ geologic and
tectonic conditions, fault characteristics, conducted field operations, and
recorded seismic activities. We publish the database in flat-file formats
(i.e., .xls and .csv tables) to facilitate its dissemination and utilization
by geoscientists while keeping it directly readable by computer codes for
convenient data manipulation. The multi-disciplinary content of this
database adds unique value to databases focusing only on seismicity data. In
particular, the collected data aim at facilitating the understanding of the
spatiotemporal occurrence of induced earthquakes, the diagnosis of
potential triggering mechanisms, and the development of scaling relations of
maximum possible earthquake magnitudes and operational parameters. The
database will boost research in seismic hazard forecasting and mitigation,
paving the way for increasing contributions of geo-energy resources to
meeting net-zero carbon emissions.
