Increment in the volcanic unrest and number of eruptions after the 2012 large earthquakes sequence in Central America

Abstract Understanding the relationship cause/effect between tectonic earthquakes and volcanic eruptions is a striking topic in Earth Sciences. Volcanoes erupt with variable reaction times as a consequence of the impact of seismic waves (i.e. dynamic stress) and changes in the stress field (i.e. sta...
