Strong ground motion measuring and recording instruments play a major role in mitigation of seismic risk. The strong ground motion near the source of an earthquake describes the effects that endanger our built environment, and is also the most detailed clue concerning the source mechanism of the earthquake.

In Southern California, there is a tsunami threat that could be triggered by a submarine landslide off the Santa Barbara or Los Angeles Basin. Based on the directivity characteristics of tsunami energy propagation, the entire U.S. west coast is vulnerable.

Data retrieval is commonly organised using relational database systems and normalised tables, but metadata, other than the primitive data types used for table columns, are often not available online nor standardised.

Metadata concepts are often better representations of the world if they are based on hierarchical models such as object-oriented.

Using southern California events, Kanamori et al. () obtained a linear relationship between the log E and local magnitude [M E = (log E − )]. We have found that this describes the northern California events well, and we have added the energy magnitude estimation to the current stage for local magnitude.

Seismology is based primarily on the observation and modeling of three orthogonal components of translational ground motions. Although effects of rotational motions due to earthquakes have long been observed (e. g., []), Richter (see, p. in []) stated that: Perfectly general motion would also involve rotations about three perpendicular axes, and three more instruments for.

Between the CSZ and the source region of the Sarguenay M w strong earthquake (Somerville et al. ), a small earthquake group is evident, indicated by the number ‘’ in Fig.

We analysed the regional depth phases generated by the two largest events in this group and found the focal depths of the two events are almost the by: Seismology lies at the core of earthquake science because its main concern is the measurement and physical description of ground shaking.

The central problem of seismology is the prediction of ground motions from knowledge of seismic-wave generation by faulting (the earthquake source) and the elastic medium through which the waves propagate (Earth structure). The Caribbean earthquakes will then be relocated using the direct search software that I developed recently with Doug Dodge, and modern earthquake source analysis will be performed using the available seismograms.

The results will help us to characterize the tsunami sources in the Caribbean. (2) Rotational Motions in Seismology ().
