Determining the spatial orientation of a fault given ground acceleration magnitude in different directions
Accelerographs measure ground acceleration in three different components of motion: east-west, north-south, and vertically (up-down). I know that fault orientation is important here, so let's say we ...

Is "seismic energy released" a regionalized variable and can be analyzed using geostatistics?
In geostatistics, we can assess and analyze regionalized variables. Tectonic stresses releases in seismically active regions by occurring earthquakes. We can calculate and estimate the seismic energy ...

Relationship between tides and earthquakes
Ide et al. (2016) suggest that earthquakes (especially those of high magnitudes) are more probable during periods of high tidal stress (during full and new moons). While they show a comprehensive ...

Calculating the displacement of a fault
In the calculation of scalar moment magnitude of an earthquake we have the formula
$$M_0=\mu AD$$
where:
$\mu$ is the shear modulus of the rocks involved in the earthquake (in Pa)
$A$ is the area ...
