Application of seismic stratigraphic techniques is nowadays standard practice for interpreting seismic datasets. The advantage of seismic stratigraphy for geological studies lies in the fact that the method combines different scales of observation: large scale remote sensing seismic measurements and the high-resolution well control logging / outcrop approach (Veeken 2007). Many workers have embraced seismic stratigraphic principles to add value to their seismic observations (e.g. Payton et al. 1977, Brown and Fisher 1976 and 1980, Rochow 1981, Halbouty 1982, Berg and Woolverton 1985, Bally 1987, Wilgus et al. 1988, Ziegler 1990, Armentrout and Perkins 1991, Cramez et al. 1993, Den Hartog Jager et al. 1993, Henri 1994, Brown 1999, Cosentino 2001, Biju-Duval 2002, Davies et al. 2004, Pomerol et al. 2005, Catuneanu 2006, Miall 2010). The proposed seismic interpretation procedure represents a systematic workflow that has proven to be a very powerful prediction tool for the evaluation of the subsurface structuration <...>

Seismic risk management in many countries around the world is a subject of crucial interest to today’s societies as the destructive effects of recent powerful earthquakes cannot be overlooked or ignored. Some of these seismic disasters that have hit Sabah (Malaysia) in 2015, Gorkha (Nepal) in 2015, Northwest Ecuador in 2016, Amatrice (Italy) in 2016, and Chaiapas (Mexico) in 2018 have affected millions of people and caused severe economic losses (Parra et al. 2016; Adhikari et al. 2015; Ramirez-Herrera et al. 2018; Faenza et al. 2016).
Accordingly, seismic design codes and frameworks are typically applied or improved after each earthquake disaster, but older buildings have not been updated to take advantage of these new methods, and they have shown poor behavior when subjected to the same seismic standards as newer constructions. <...>

The notes cover the second semester of a twosemester seismological course that the author teaches in the Department of Geophysics at the Colorado School of Mines The rst semester is devoted to the basics of elasticity theory of seismic sources and plane wave propagation in D isotropic media I begin with reviewing some relevant results from the rst part of the course in Chapters 1 and 2 <...>

Seismicity has been detected within the central "granite-free" part of the Black Sea depression, which earlier was considered aseismic.   The seismicity defines specific zones in the depression and its margins. In the depression, epicenters are grouped into diagonal linear chains separating large blocks.   The vertical distribution of seismicity has allowed us to distinguish four main levels in the Black Sea tectonosphere, which differ in elastic and strength properties: sedimentary layers, brittle crystalline crust, plastic upper mantle, and deeper mantle which is considerably more homogenous. At various levels, structures show azimuthal discordance. The plastic upper mantle appears to be connected with the asthenosphere.  It is most uplifted under the "granite-free" part of the Black Sea depression and is apparently responsible for its formation. A mantle asthenolith (or asthenolithes) probably occur there.
