Seismic magnitude scales the 1989 Loma Prieta earthquake, the Marina district of San Francisco was one of the most damaged areas, though it was nearly 100 km from the epicenter. Geological structures were also significant, such as where seismic waves passing under the south end of San Francisco Bay reflected off the base of the Earth's crust towards San Francisco and Oakland. A similar effect channeled seismic waves between the other major faults in the area. An earthquake radiates energy in the form of different kinds of seismic waves, whose characteristics reflect the nature of both the rupture and the earth's crust the
Therapeutic effect strategy or agent. To maximize therapeutic effects (desired) and minimize side effects (undesired) requires recognition and quantification of the treatment in multiple dimensions. In the specific case of targeted pharmaceutical interventions a combination of therapies is often needed to achieve the desired results. Therapeutic effect Therapeutic effect refers to the responses(s) after a treatment of any kind, the results of which are judged to be useful or favorable. This is true whether the result was expected, unexpected, or even an unintended consequence. An adverse effect (including nocebo) is the converse and refers to harmful or undesired responses(s).
