Title

Reykjanes Peninsula microseismicity (NERC Grant NE/W004690/1)

Abstract

Contains location and associated parameter information for microseismicity detected in the Reykjanes peninsula between June 2020 and August 2021. Primary detection and location carried out using Quakemigrate. Template matching used to find very small magnitude events. GrowClust used to obtain accurate relative relocations. Local magnitudes of events also computed. Data from a total of 42 stations were used for the detection and location process. Repository also includes the 1-D velocity model used for the relocation.

Lineage

Quakemigrate is an advanced computational tool for the detection and location of earthquakes through the application of waveform migration and stacking to data collected by arrays of seismometers. It has been widely applied throughout the world, but was originally developed by the Cambridge Volcano Seismology Group for application to data collected in Iceland. It is particularly adept in the presence of noisy data, and for discriminating between overlapping events. Growclust is a technique that enables accurate relocation of earthquake hypocenters based on waveform cross-correlation. The techniques is particularly effective when earthquakes exhibit similar waveforms, which turns out to be the case in Reykjanes. This property also facilitates the recovery of smaller events using match filtering.
