PKP travel times at near antipodal distances: implications for inner core anisotropy and lowermost mantle structure
Previous studies from PKP(AB^DF) differential travel times at large distances suggest that the central part of the inner core is very anisotropic. These differential times, however, can be affected greatly by strong heterogeneity in the lowermost mantle. Here we examine a unique data set of PKP travel times from global digital and analog stations at near antipodal distances, where the effects o...
متن کاملA Random Walk with Exponential Travel Times
Consider the random walk among N places with N(N - 1)/2 transports. We attach an exponential random variable Xij to each transport between places Pi and Pj and take these random variables mutually independent. If transports are possible or impossible independently with probability p and 1-p, respectively, then we give a lower bound for the distribution function of the smallest path at point log...
متن کاملTime dependence of PKP(BC)–PKP(DF) times: could this be an artifact of systematic earthquake mislocations?
Differential inner core rotation was first detected from time-dependent observations of differential travel times between PKP(DF) waves (which go through the inner core) and PKP(BC) waves (which turn at the bottom of the outer core) (Song and Richards, 1996). Criticisms concerning the reported detection have been raised, the most significant one being the possible bias from potential systematic...
متن کاملTravel Times of Longitudinal Waves From Surface Foci.
Tables and graphs for travel times of seismic waves propagated through the earth are based on earthquake records. This requires accurate knowledge of the longitude and latitude of the corresponding epicenters, focal depths, and origin times. It is highly desirable to compare the resulting travel time curves and tables with results derived from experiments in which all four fundamental quantitie...
متن کاملEarthquakes Around and Mountains the Pacific
Even after a century of intensive study, the problem of the origin of mountain systems remains as possibly the greatest enigma of the earth sciences. Specifically, what is the origin of mountain-building forces, and how are these forces manifested in the crustal rocks of the earth's surface? Field geologists who have studied such classical mountain systems as the Alps and the Appalachians have ...
