Earthquakes: slow down for safety
Article Abstract:
Slow earthquakes can be explained in terms of coefficient of friction, which depends on slip speed and past slip history. According to G.K.Gilbert's analysis in 1884, the strain in the Earth's crust increases to a point where it overcomes the starting friction on the fractured surface. Sudden motion relives the strain, and is followed by a period of relative calm in which the strain is gradually rebuilt. The slow earthquake at the San Andreas fault in California in 1992, caused minimum damage, as it occurred near an area similar to the transition from stick-slip to stable sliding.

Earthquakes triggered by silent slip events on Kilauea volcano, Hawaii
Article Abstract:
Swarms of high-frequency earthquakes that accompany otherwise silent slips on Kilauea volcano, Hawaii, are reported, where the earthquakes, located at depths of 7-8 km, constrain the slow slip to be at comparable depths because they must fall in zones of positive Coulomb stress change. Detection of such events could lead to a method for quantifying the increased hazard during slow-slip events, since triggered events have the potential to grow into destructive earthquakes.

New insights into old earthquakes
Article Abstract:
Scientists believe that the elastic rebound theory in geodetic surveys from the nineteenth-century can be useful in the prediction of future earthquakes. The research work of Harry Fielding Reid in the nineteen century is remarkable in its accuracy and invaluable in historical research regarding the great San Francisco earthquake of Apr 18, 1906.
