Resolvability of the centroid-moment-tensors for shallow seismic sources and improvements from modelling high-frequency waveforms

Hejrani, Babak; Tkalčić, Hrvoje

Description

Shallow earthquakes in the depth range 0–30 km make up more than 60% of all world's earthquakes. However, resolving their seismic source parameters such as the depth and moment tensor components presents a challenge. Here, we investigate the effect of frequencies higher than 0.025 Hz on centroid‐moment‐tensor inversion for the earthquakes occurring in the top 10 km of the Earth's crust. For a synthetic source located at the depth of 1 km, the maximum amplitude of ground motion due to...[Show more]
