Real-time W phase inversion during the 2011 off the Pacific coast of Tohoku Earthquake
2011
Overview
The real time W phase source inversion algorithm was independently running at three organizations (USGS, PTWC and IPGS) at the time of the 2011 off the Pacific coast of Tohoku Earthquake. Valuable results for tsunami warning purposes were obtained 20 min after the event origin time. Within the next hour, as more data became available, the W phase solutions improved, and converged to a common result (
M
w
≈ 9.0, dip ≈ 14°). A post-mortem W phase analysis using data selection based on pre-event noise confirmed the
M
w
= 9.0 result and yielded a best double couple given by (strike/dip/rake = 196°/12°/85°). We also ran the algorithm with increasingly longer periods (
T
≈ 1500 sec) to test for the possibility of additional slow slip. The seismic moment remained stable, confirming the prior results.
