Assuming that earthquakes are the realization of a stochastic point process and magnitude distribution all is described by Gutenberg‐Richter law with constant b value, we model occurrence rate density in space time means an epidemic model. The computed sum two terms, one representing independent, or spontaneous activity, other activity induced previous earthquakes. While first term depends only on space, second factored into three terms include magnitude, time, location, respectively, past...
Earthquakes are regarded as the realization of a point process modeled by generalized Poisson distribution. We assume that Gutenberg‐Richter law describes magnitude distribution all earthquakes in sample, with constant b value. model occurrence rate density space and time sum two terms, one representing independent, or spontaneous, activity other induced previous earthquakes. The first term depends only on is continuous function geometrical coordinates, obtained smoothing discrete past...
We model the spatial and temporal pattern of seismicity during a sequence moderate‐magnitude normal faulting earthquakes, which struck in 1997 Umbria‐Marche sector Northern Apennines (Italy), by applying Dieterich (1994) rate‐ state‐dependent constitutive approach. The goal is to investigate rate earthquake production caused repeated coseismic stress changes computed through 3‐D elastic dislocation homogeneous half‐space. reference assumed time independent, it estimated smoothing that...
A field study after the Perugia earthquake of 29 April 1984 provided more than 300 well-recorded events concentrated within two parallel clusters separated by 2 km and trending along Apenninic direction. The length aftershock area is 14 km, focal depths being shallower 8 km. Relocation main event places epicenter at southern end zone, suggesting a rupture propagation from SE to NW. Most mechanisms are consistent with normal faulting. spatial distribution seismicity suggests that Gubbio fault...
Abstract The characteristic earthquake hypothesis is the basis of time‐dependent modeling recurrence on major faults. However, not strongly supported by observational data. Few fault segments have long historical or paleoseismic records individually dated ruptures, and when data parameter uncertainties are allowed for, form distribution difficult to establish. This case, for instance, Corinth Gulf Fault System (CGFS), which documents about strong earthquakes exist at least 2000 years,...
Abstract We forecast time‐independent and time‐dependent earthquake ruptures in the Marmara region of Turkey for next 30 years using a new fault segmentation model. also augment Brownian passage time (BPT) probability with static Coulomb stress changes (ΔCFF) from interacting faults. calculate M w > 6.5 26 individual sources region. consider multisegment rupture model that allows higher‐magnitude over some segments northern branch North Anatolian Fault Zone beneath Sea.

The present research aims at verifying whether there are significant differences between Land Use/Land Cover (LULC) classifications performed using Landsat 8 Operational Imager (OLI) and Sentinel-2 Multispectral Instrument (MSI) data—abbreviated as L8 S2. To comprehend the degree of accuracy these classifications, both S2 scenes covering study area located in Basilicata region (Italy) acquired within a couple days August 2017 were considered. Both images geometrically atmospherically...
We revisit the issue of so‐called Båth's law concerning difference D 1 between magnitude main shock and second largest in same sequence. A mathematical formulation problem is developed with only assumption being that all events belong to self‐similar set earthquakes following Gutenberg–Richter distribution. This model shows a substantial dependence on thresholds chosen for shocks aftershocks this way partly explains large values reported past. Analysis New Zealand Preliminary Determination...
The concept of background seismicity is strictly related to the identification spontaneous and triggered earthquakes. definition foreshocks, main shocks aftershocks currently based on procedures depending parameters whose values are notoriously assumed by subjective criteria. We propose a method for recognizing induced statistically. Rather than using binary distinction events in these two categories, we prefer assign each them probability being independent or triggered. This comes from an...
Abstract An estimate of the expected earthquake rate at all possible magnitudes is needed for seismic hazard forecasts. Regional magnitude frequency distributions obey a negative exponential law (Gutenberg‐Richter), but it unclear if individual faults do. We add three new methods to calculate long‐term California rupture rates existing Uniform Earthquake Rupture Forecast version 3 efforts assess method and parameter dependence on results faults. All solutions show strongly characteristic...
In recent years, new approaches for developing earthquake rupture forecasts (ERFs) have been proposed to be used as an input probabilistic seismic hazard assessment (PSHA). Zone- based with seismicity rates derived from catalogs are commonly in many countries the standard national models. Italy, a single zone- ERF is currently basis official model. this contribution, we present eleven ERFs, including five zone-based, two smoothed seismicity-based, fault- based, and geodetic-based, PSH model...

Abstract By using the accelerometric data obtained during heaviest earthquakes that occurred in Friuli 1976, an attempt was made to obtain a law of attenuation northeastern Po river area as dependence on frequency. The study carried out by comparison power spectra entire accelerograms at different distances. In frequency range 0.1 10 Hz, Q value found which proportionally dependent f n , with = 1.1. This result can be considered valid for region and distances up about 200 km from epicentral area.
Earthquake forecasts are usually underinformed, and can be plagued by uncertainty in terms of the most appropriate model, parameter values used that model. In this paper, we explore application two different models to same seismogenic area. The first is a renewal model based on characteristic earthquake hypothesis uses historical/palaeoseismic recurrence times, fixed rupture geometries. hazard rate modified Coulomb static stress change caused nearby earthquakes occurred since latest...
Nowadays, the huge production of Municipal Solid Waste (MSW) is one most strongly felt environmental issues. Consequently, European Union (EU) delivers laws and regulations for better waste management, identifying essential requirements disposal operations characteristics that make hazardous to human health environment. In Italy, define, among other things, sites be classified as “potentially contaminated”. From this perspective, Basilicata region currently Italian regions with highest...
The spatial pattern of the b value frequency‐magnitude relation has been analyzed using gridding techniques beneath Mount Etna, Italy. A regional data set 2900 events with M d (duration magnitude) ≥1.5 up to 15 km depth occurring between August 1999 and December 2005 used. Two regions an abnormally high have found, one centered southern part Valle del Bove, above 6 below sea level (bsl) deep basement, other summit region 2 bsl east Central Craters. We can infer that these anomalies are...
Abstract The Alto Tiberina Fault system, located in Central Italy, is an active structure about 60 km long composed of a principal low-angle normal fault and several minor synthetic antithetic splays. system monitored by dense seismic network, giving us the opportunity to construct high-definition catalogs with low completeness magnitude. We analyze clustering properties 2010-2015 seismicity using 3D stochastic declustering algorithm that also includes earthquakes’ depth. demonstrate...

Abstract The earthquake size distribution is well described by the Gutenberg Richter Law, controlled b-value parameter. In recent decades, a great variety of methods for estimating have been proposed scientific community, despite simplicity this relationship. All these underlie different views individual modelers and, therefore, often generate inconsistent results. study, we perform seismological experiment in which compare different, commonly adopted, methodologies, to estimate completeness...
