Abstract

Detection and location of small (mlcroselsmlc) earthquakes Is critical due to Increasing subsurface lluld injection activities.
Accurately locating recorded earthquakes is paramount for Improving productivity and reducing potential hazards. A
fundamental parameter for location accuracy Is the 30 velocity mode. Current seismological velocity building techniques based
on large earthquakes rely on high slgnal-to-nolse data. I present a new method to jointly invert for the velocity structure and
accurately locate small magnitude earthquakes that is suitable for microselsmlc monitoring. Thus, it Is useful to for varied
applications from induced seismicity to teleselsmlc monitoring.
