MINAS - IPOC Mini Arrays

Three temporary (2 years) 10 element small-aperture arrays for IPOC.

Objectives:

• Detection/location of seismic signals without clear signal onset (e.g. tremors)
• Determination of slowness and azimuth of scattered energy (secondary arrivals); if present measurements from all three mini-arrays can be combined to estimate locations of scatterers
• Test of array methods for enhancing ambient noise Green's function estimates, e.g. by stacking. Also we can cross-check actual propagation directions against the great-circle path assumption
• Test of methods for tracking ruptures using high frequency arrivals from moderate size earthquakes

• Improve detection threshold for classic (impulsive) earthquakes
