“…This approach was later successfully adopted for the investigation of regional seismicity in different regions (Guilhem & Dreger, 2010;Tsuroka, Kawakatsu, & Urabe, 2009). Following this general idea, a growing number of recent works attempt to achieve a similar joint inversion of location and moment tensor for microseismic events (Anikiev, Valenta, Stanek, & Eisner, 2014;Chambers, Dando, Jones, Velasco, & Wilson, 2014;Gharti, Oye, K€ uhn, & Zhao, 2011;Kawakatsu, 1998;Krieger, 2011;Vera Rodriguez, Sacchi, & Gu, 2012;Weber, 2006;Zhebel & Eisner, 2012), revealing the extreme interest in this type of applications for microseismicity monitoring and characterization. In fact, although a joint detection, location, and source parameter inversion modeling high-frequency signals is very demanding and requires the simultaneous determination of many unknowns, the large size of microseismic monitoring networks and the often available 3D network geometries are helpful to resolve this challenging inversion problem.…”
