A real-time seismic monitoring infrastructure has been recently installed and it is actually operating in southern Italy, whose main purposes are to rapidly issue an earthquake alert, to provide near-real-time maps of the peak ground motion and intensity shaking and to test the feasibility of earthquake early warning following moderate to large earthquakes occurring along the southern Apenninic...

for the first time, on the basis of spitak earthquake experience (armenia, december 1988), it was found that an earthquake causes intensive and prolonged radon releases that are quickly dispersed in the open air and that is why they are not usually registered but contrastingly displayed in covered premises (such as dwelling houses, schools, kindergartens) even if they are at a considerable dist...

Earthquake is one of disaster that when happened causes many problems in economic and society in Iran, so earthquake disaster management is necessary for decreasing these problem effects. Because of most related data with earthquake and its effects have spatial properties, so GIS can be used as effective tool for managing and decision making in disaster. In some countries such as Iran, disaster...

S U M M A R Y We investigate the 2007 Pisco, Peru, earthquake (M8.0) using seismological and geodetic data. Analysis of teleseismic records indicates that the earthquake is characterized by a steadily increasing moment rate, with the maximum occurring between about 55 and 70 s and the associated slip occurring about 40 km south of the epicentre. We combine InSAR data from L-band (ALOS) and C-ba...

Probabilistic seismic hazard analysis (PSHA) is classically performed through the Cornell approach by using a uniform earthquake distribution over the source area and a given magnitude range. This study aims at extending the PSHA approach to the case of a characteristic earthquake scenario associated with an active fault. The approach integrates PSHA with a high-frequency deterministic techniqu...

At subduction zones, transient aseismic slip occurs either as afterslip following a large earthquake or as episodic slow slip events during the interseismic period. Afterslip and slow slip events are usually considered as distinct processes occurring on separate fault areas governed by different frictional properties. Continuous GPS (Global Positioning System) measurements following the 2016 Mw...

The 1985 prediction of a characteristic magnitude 6 Parkfield earthquake was unsuccessful, since no significant event occurred in the 95% time window (1985–1993) anywhere near Parkfield. The magnitude 6 earthquake near Parkfield in 2004 failed to satisfy the prediction not just because it was late; it also differed in character from the 1985 prediction and was expectable according to a simple n...

Point process models are useful for describing phenomena occurring at random locations and/or times. Following a review of basic concepts, some important models are surveyed including Poisson processes, renewal processes, Hawkes processes, and Markovian point processes. Techniques for estimation, simulation and residual analysis for point processes are also briefly discussed. A point process is...

Abstract Deep-focus earthquakes in the Tonga–Fiji subduction zone make up greater than 66% of the globally recorded deep seismicity. The high number of deep-focus seismicity in this active subduction zone allows us to search for deep-focus similar earthquake pairs and repeating earthquakes. We compile a waveform dataset for deep earthquakes with magnitude above 4.7 occurring in the Tonga–Fiji–K...
