Abstract:
The dataset includes located earthquakes with origin time, location and magnitude and pick information.
The dataset consists of 11 months of seismicity data collected by 26 ocean bottom seismometers along around 160 km of the Knipovich Ridge rift axis.
Earthquakes were detected using Lassie, automatically picked with PSPicker followed by manual re-picking. Amplitudes were picked automatically with automag in SEISAN. Location was performed using HYPOSAT. The dataset includes all located events without any quality control.
