Relocated locations of NMSZ hypocenters using hypoDD-SVD inversion method on broadband data from year 2000~2019
Description
The intraplate New Madrid Seismic Zone (NMSZ) is located in the northern Mississippi Embayment and over 200 earthquakes are recorded every year. We relocated 4131 hypocenters for earthquakes occurring between 2000 and 2019 using the HypoDD double-difference relocation technique. The input catalog data are broadband data obtained from the Center for Earthquake Research and Information (CERI) earthquake catalog. We used earthquakes recorded from Jan 1st, 2000 to Dec 31st, 2019 within an area from 35.5 𝑁 to 36.9 𝑁 and from 90.6 𝑊 to 89.2 𝑊. This dataset includes 4568 earthquakes recorded by 314 stations.
