Detection of an ultralow velocity zone at the core-mantle boundary using diffracted PKKPab waves
[1] Seismic phases diffracted around Earth’s core contain information about lowermost mantle wave speeds. By measuring the slowness of incident diffracted energy from array recordings, seismic velocity along the diffracted path can be estimated. Here we apply this principle to diffraction of the major arc seismic phase PKKPab recorded at the Canadian Yellowknife array to estimate P wave velocit...
متن کاملProbing an Ultra-low velocity zone at the Core Mantle Boundary with 13 and S Waves
Recent studies of the core-mantle boundary (CMB) have revealed some very anomalous tructures interpreted in terms of ultra low velocity zones (ULVZ). However, there remains considerable uncertainties about their physical descriptions or even if they occur above or below the CMB. They have only been detected in isolated situations using rather special techniques; these includes: distortions in S...
متن کاملDetermining Shear - Wave Velocity from Diffracted S H Waves
Profiles of SH waves diffracted around the core (Sd) for three deep events at stations across North America and the Atlantic (4 = 92 ° to 152 °) are used to determine the properties of the lower mantle in the vicinity of the core-manUe boundary (CMB). The S-wave velocity above the CMB is found to be tic = 7.22 __ 0.1 km/sec, in agreement with gross earth models, but higher than previously repor...
متن کاملLow-velocity damaged structure of the San Andreas Fault at Parkfield from fault zone trapped waves
[1] We used dense linear seismic arrays across and along the San Andreas Fault (SAF) at Parkfield, California to record fault zone trapped waves generated by explosions and microearthquakes in 2002. Prominent trapped waves appeared at stations close to the SAF main fault trace while some energy was trapped in the north strand at the array site. Observations and 3-D finitedifference simulations ...
متن کاملMega ultra low velocity zone and mantle flow
Mantle flow in Earth’s interior has been inferred from a variety of geo-disciplines. Two continentalscale, nearly antipodal, large low shear velocity provinces (LLSVPs) at the base of the mantle, thought to be dense and chemically distinct likely play a significant role in mantle dynamics and plume generation, and hence are targeted in a high-resolution seismic study. We analyze broadband SPdKS...
