Microseismic catalogue of the surface network with local magnitude by B. Dyer - Soultz-sous-Forêts 2000 Stimulation

Description

Microseismic catalogue with local magnitude of the 2000 episode at Soultz-sous-Forêts calculated by B. Dyer (Semore Seismic) using the surface network. 
Number of events: 51.
Microseismic monitoring of the hydraulic programme at Soultz took place between June 30th and July 18th. The catalogue contains the 51 largest events detected on the surface network during the 2000 episode. Each event identity and location in the catalogue was assigned by correlating the times of the events on the surface network with the times of the microseismic events from the catalogue of the downhole network of B. Dyer (available here). Some discrepancies of few minutes for a same event between the two catalogues are possible because of the gap in time between the twok clocks on the two data acquisition systems. Some locations are missing because of insufficient picks, due to noise, or insufficient data, due to one or more sensors being inoperative.
Time period: 30/06/2000 23:09 - 25/07/2000 09:06 (UTC time).

The data parameters are the following:
Column 1: Event number
Column 2: Date (UTC)
Column 3: Time (UTC)
Column 4: Easting from GPK1 wellhead *
Column 5: Northing from GPK1 wellhead *
Column 6: Depth from GPK1 wellhead *
Column 7: Latitude WGS84 **
Column 8: Longitude WGS84 **
Column 9: Elevation WGS84 **
Column 10: Local magnitude

* The local coordinate system is based on the UTM32 system.
** Latitude, longitude and elevation have been derived from the local coordinate system.
