Deep CO2 emissions characterize many nonvolcanic, seismically active regions worldwide,
and the involvement of deep CO2 in the earthquake cycle is now generally recognized …

Fluids supplied by stored magma at depth are causal factors of volcanic unrest, as they can
cause pressurization/heating of hydrothermal systems. However, evidence for links between …

This paper reports a review on the relationship between seismic activity and the emissions
of CO2 and radon. Direct, indirect and sampling methods are mainly employed to measure …

The spatial and temporal evolutionary mechanisms of volatile components at plate
boundaries and their potential as earthquake precursors are not well understood. Based on …

Although many mechanisms of earthquake-induced hydrological response have been
proposed in recent decades, the origins of these responses remain enigmatic, and a …

Earthquakes are catastrophic natural disasters that cause extensive damage to
infrastructure and disrupt the lives of millions worldwide. Beyond the immediate physical and …

Fluid–earthquake interplay, as evidenced by aftershock distributions or earthquake-induced
effects on near-surface aquifers, has suggested that earthquakes dynamically affect …

Maar‐diatreme volcanoes are small volcanic structures with a funnel‐shaped crater
surrounded by a tephra‐ring. They are usually formed by the explosive phreatomagmatic …

In the search for precursors to earthquakes, correlation has been found between
geochemical characteristics of soil gases and seismic activity. In this paper we present …

Static and dynamic stress, along with earthquakes, can trigger the emission and migration of
crustal fluids, as frequently observed on the surface and within the upper crust of tectonically …
