article_snippet.sent: The map shows inferred faults (dashed) at the top of the Blenburger formation, injection wells (red squares), two production wells (API 36734045 and 36734139) with significant brine production near the faults (pink arrows) and earthquake epicentres (coloured circles) recorded by the temporary seismic network (triangles)
article_snippet.sent: In inferred faults (dashed) at the top of the Blenburger formation, injection wells (red squares), two production wells (API 36734045 and 36734139) with significant brine production near the faults (pink arrows) and earthquake epicentres (coloured circles) recorded by the temporary seismic network (triangles), there have been more than 950 magnitude 2 or higher quakes so far this year, according to the USGS.
