Earth's Correlation Wavefield: Late Coda Correlation

Pham, Thanh-Son; Tkalčić, Hrvoje; Sambridge, Malcolm; Kennett, Brian

Description

Cross correlation of seismograms provides new information on the Earth both through the exploitation of ambient noise and specific components of earthquake records. Here we cross‐correlate recordings of large earthquakes on a planetary scale and identify a range of hitherto unobserved seismic phases in Earth's correlation wavefield. We show that both arrivals with the timing expected for the regular seismic wavefield and previously unexplained phases are produced by interference between seismic...[Show more]
