After a brief (incomplete) review of pre-seismic (strain-producing) phenomena, we describe our findings about the pre-seismic phase of the the April 6, 2009 L'Aquila earthquake, giving a few more details with respect to previous papers. Most past observations of crustal strain did not detect any pre-seismic deformation and have been used to constrain the size and strength of the source of possible pre-seismic phenomena. With respect to these, we performed a rather more sophisticated approach to… Expand
Space geodetic data (GPS) and earthquake forecasting: examples from the Italian geodetic network
Some considerations are given about attempts at predicting impending earthquakes by the use of space geodetic (GPS) observations in the Italian peninsula. Both short (weeks to days) andExpand

Competition between preslip and deviatoric stress modulates precursors for laboratory earthquakes
Abstract Variations in elastic wave velocity and amplitude prior to failure have been documented in laboratory experiments as well as in a limited number of crustal earthquakes. These variations haveExpand

Earthquake forecasting and hazard assessment: a preface
Forecasting potentially damaging future earthquakes and eruptions is a basic (and expected) outcome of scientific research. Several kinds of forecast are presently performed by considering differentExpand

A model is presented which allows us to reexamine the interpretation of velocity anomalies observed before some earthquakes occur. This model extends the well-known dilatancy models by accounting forExpand
