Recently, Morner discussed his model of glacio-isostatic compensation in the light of new seismological models of the upper mantle below Fennoscandia (Miimer, 1990). He concluded that the P-wave velocity distribution is in “full agreement” with his estimate of the viscosity distribution as inferred from glacio-isostatic relaxation. Whereas the consistency of seismological and geodynamical earth...

Ground-motion (attenuation) relations are used to estimate strong ground motion for many engineering and seismological applications. Where strongmotion recordings are abundant, these relations are developed empirically from strong-motion recordings. Where recordings are limited, they are often developed from seismological models using stochastic and theoretical methods. However, there is a larg...

Seismic retrofitting of important structures is essential in seismological active zones. The importance is doubled when it comes to some buildings like schools, hospitals, bridges etc. because they are required to continue their serviceability even after a major earthquake. Generally, seismic retrofitting codes have paid little attention to retrofitting of foundations due to its construction co...

Recent global expansion of seismic data motivated a number of seismological studies of the Earth's inner core that proposed the existence of increasingly complex structure and anisotropy. In the meantime, new hypotheses of dynamic mechanisms have been put forward to interpret seismological results. Here, the nature of hemispherical dichotomy and anisotropy is re-investigated by bridging the obs...

We present the architecture of a so-called Seismic Data Management and Mining System (SDMMS) for quick and easy data collection, processing, and visualization. The proposed SDMMS architecture includes, among others, a seismological database for efficient and effective querying and a seismological data warehouse for OLAP analysis and data mining. We provide template schemes for these two compone...

Seismology offers the highest-resolution view of mantle structure. In the decades since Morgan [1971] first proposed deep-mantle plumes, seismologists have used increasingly sophisticated methods to look for evidence of such structures, but so far they have had little success. This abstract outlines the relevant seismological methods for non-specialists and summarizes the current state of knowl...
