Seismic and thermal precursors of crater collapses and overflows at Stromboli volcano.

Lava overflows are highly hazardous phenomena that can occur at Stromboli. They can destabilize the crater area and the "Sciara del Fuoco" unstable slope, formed by several sector collapses, which can generate potentially tsunamigenic landslides. In this study, we have identified precursors of the October-November 2022 effusive crisis through seismic and thermal camera measurements.

Connection between Rn emission and geophysical-geochemical parameters recorded during the volcanic unrest at Campi Flegrei caldera (2011-2017).

Studies concerning Rn emission from soils are growing interest in the Earth Sciences, due to the gas potential as a tracer of natural phenomena. This paper presents a study of radon monitoring in two sites of Campi Flegrei caldera (Neaples, Italy) during the period July 1, 2011-December 31, 2017. This area was characterized by several phases of volcanic unrest.

Geophysical precursors of the July-August 2019 paroxysmal eruptive phase and their implications for Stromboli volcano (Italy) monitoring.

Two paroxysmal explosions occurred at Stromboli volcano in the Summer 2019, the first of which, on July 3, caused one fatality and some injuries. Within the 56 days between the two paroxysmal explosions, effusive activity from vents located in the summit area of the volcano occurred. No significant changes in routinely monitored parameters were detected before the paroxysmal explosions.

Continuous radon monitoring during seven years of volcanic unrest at Campi Flegrei caldera (Italy).

This is a seven-year study (1/7/2011-31/12/2017) of radon monitoring at two sites of Campi Flegrei caldera (Neaples, Southern Italy) that in the last 70 years experienced repeated phases of volcanic unrest. The sites are equipped with devices for radon detection, based on the spectrometry analysis of the α-particles of radon daughters. A hybrid method, as combination of three known methods, is applied for the identification of residuals (anomalies) and trends of the time series of Radon.

Physiologic and symptomatic responses of cardiac patients to resistance exercise.

The purpose of this study was to investigate the symptomatic and physiologic responses during moderate to heavy resistance exercise in a population with coronary artery disease. After at least 12 weeks of aerobic training without experiencing complications, 15 male cardiac patients were selected for the study. Approximately one week after a graded exercise test (GXT), each patient's maximal voluntary contraction (MVC) was determined on seven upper-body Nautilus machines.
