Exploration Activity: Micro-Earthquake At Kilauea East Rift Geothermal Area (Kenedi, Et Al., 2010)

Exploration Activity Details
Location Kilauea East Rift Geothermal Area
Exploration Technique Micro-Earthquake
Activity Date 2006 - 2010

Usefulness useful
DOE-funding Unknown

 
Exploration Basis
This study was conducted to gain a more detailed seismic velocity model.
 
Notes
A network eight of down-hole seismometers were placed in the Puna geothermal field. The instruments range in depth from 24 - 210 m. Five stations were equipped with 2 Hz Geophones and three had 4.5 Hz Geophones. Over 4000 microseismic events were recorded during this study. Most earthquakes recorded in the region were less than 0.5 and occurred 2-3 km deep. Three analytical techniques were applied to this study: Shear wave splitting, double difference earthquake location, and 3-D tomography. This study was beneficial in helping to improve the local velocity model, identify fault and fracture orientations, and locate zones of high and low velocities. Based on earthquake sizes, locations, and depths the evidence from this study suggests that the power plant does have an affect on local seismicity.
