Thermal anomalies and fluid geochemistry framework in occurrence of the 2000-2001 Nizza Monferrate seismic sequence ( northern Italy ) : Episodic changes in the fault zone heat flow or chemical mixing phenomena ?

Abstract

The paper discusses the correlation between the heating of shallow groundwater over a 10× 20 km wide area close to the town of Nizza Monferrato (Piemonte Region, Northern Italy) and the concomitant local seismic sequences during the period August 2000 – July 2001. The first seismic sequence started on 21 August 2000 with a Ml = 5.2 earthquake. Within few… (More)
