“…The series connection allows to avoid an intermediate evaporation step in the Lariviere et al (2005) procedure, with a significant reduction of its duration. Loading a sample in the Sr resin at 4-M HNO 3 did not affect the column capacity factor k' , as previously described (Plastino et al 2010). After the elution in Sr resin, as shown in Fig.…”

“…Within the framework of the Environmental Radioactivity Monitoring for Earth Sciences (ERMES) project carried out at the Instituto Nazionale di Fisica Nucleare (INFN) Gran Sasso National Laboratory, 1-L groundwater samples have been collected weekly since 2008 at ten different sites located in the underground laboratory (Plastino et al 2010;Plastino et al 2011). In order to analyze with high precision such large number of samples necessary for the development of 226 Ra time series, it has been proposed to develop a new analytical technology, which would be based on ICP-MS.…”

Background: Inductively coupled plasma mass spectrometry (ICP-MS) techniques have been widely used for analysis of long-lived environmental radionuclides. In this paper, we present an optimization of the sector field (SF)-ICP-MS technique for the analysis of 226 Ra in groundwater samples using a method of pre-concentration of radium in water samples. Methods: The separation protocol and a sequential application of ion exchange and extraction chromatography have been optimized, and related polyatomic interferences and matrix effects affecting the

“…In particular very intense and extended anomalies appear near tectonic lineaments since 30 March (few hours before the foreshock with M L ∼4.1) during the same period interested by anomalous variations of different geophysical parameters independently reported by several authors (e.g., Caporali, 2009;Pergola et al, 2010;Martinelli et al, 2009;Rozhnoi et al, 2009;Plastino et al, 2010). Among the others, particularly important seems the V P /V S seismological observations that Lucente et al (2009) …”

Abstract.A self adaptive approach (RST, Robust Satellite Technique) has been proposed as a suitable tool for satellite TIR surveys in seismically active regions devoted to detect and monitor thermal anomalies possibly related to earthquake occurrence. In this work, RST approach has been applied to 15 years of AVHRR (Advanced Very High Resolution Radiometer) thermal infrared observations in order to study the 6 April 2009 Abruzzo earthquake. Preliminary results show clear differences in TIR anomalies occurrence during the periods used for validation (15 March-15 April 2009) and the one (15 March-15 April 2008) without earthquakes with M L ≥4.5, used for confutation purposes. Quite clear TIR anomalies appears also to mark main tectonic lineaments during the preparatory phases of others, low magnitude(3.9

Abstract.A possible geophysical mechanism based on the conception of criticality and on new aspects of biological effects caused by electromagnetic fields is discussed as a stimulus to the unusual animal behavior prior to large earthquakes. This mechanism is related to transient electric signals of low frequency and intensity, which are emitted from the pre-focal area several days before the impending earthquake and fulfill all the conditions set by a recent bioeffect model.
