[1] Earthquake source time functions deconvolved from teleseismic broadband P wave recordings are used to examine rupture variations for 417 underthrusting earthquakes located on the interplate interface in circum-Pacific subduction zones. Moment-scaled duration of significant moment release varies with depth, with longer-duration events occurring in the shallowest 20 km of the megathrusts. The...

Joint inversions are now commonly used in the earth sciences. They have been developed to better understand the structure of the earth, since they provide more constraints on the inverted parameters. We propose a new process to simultaneously invert several data sets in order to better image 3D crustal and upper mantle structures. Our inversion uses three kinds of data that present good complem...

I present a teleseismic waveform study of the lithospheric structure beneath the Tibetan Plateau, using data collected during the 1991-1992 SinoUS Tibet seismic recording experiment. Crustal thickness at each of the 11 broadband stations is estimated from the differential travel time between the Moho P -to-S converted phase and direct P . I demonstrated that this estimation is not sensitive to ...

a r t i c l e i n f o a b s t r a c t USArray has facilitated significant advancement in tomographic models and methodologies. While there persists a fundamental tradeoff between horizontal and vertical resolution due to the components of the wave train analyzed, advances in joint inversions are continuing to refine the tomographic images generated with USArray. The DNA13 model incorporates tel...

The InSight mission (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) has been collecting high-quality seismic data from Mars since February 2019, shortly after its landing. Marsquake Service (MQS) is the team responsible for prompt review of all recorded by InSight's seismometer (SEIS), marsquake event detection, curating seismicity catalogues. Until sol 1011 (end...
