Arculus, R.J., 1987. The significance of source versus process in the tectonic controls of magma genesis. In: S.D. Weaver and R.W. Johnson (Editors), Tectonic Controls on Magma Chemistry. J. Volcanol. Geotherm. Res., 32: 1-12. Despite the association of certain characteristic trace-element signatures with particular tectonic environments of eruption, there are accumulating data which would resu...

Seismic hazard analyses are associated with large uncertainties when historical data are insufficient to define secular rates of seismicity. Such uncertainties may be decreased with geological data in areas where seismicity is shallow and produced by Quaternary faulting. To illustrate, we examine intraplate Japan. Large intraplate earthquakes in Japan characteristically produce surface ruptures...

Seismic hazard assessment in several sites worldwide depends on two or more seismic sources. Many countries affected by subduction zones have strong motions earthquakes originated at least important In Mexico, interplate (subduction process) epicenters located the Pacific coast with hypocenter depths less than 45 km and intraplate (intermediate-depth earthquakes) normally inside continent depth...
