Island arcs can either be active or inactive based on their seismicity and presence of volcanoes.

Environmental impact of hydraulic fracturing in the United States

methane leakage
Environmental impact of hydraulic fracturing in the United States has been an issue of public concern, and includes the potential contamination of ground and surface water, methane emissions, air pollution, migration of gases and hydraulic fracturing chemicals and radionuclides to the surface, the potential mishandling of solid waste, drill cuttings, increased seismicity and associated effects on human and ecosystem health.

Guardia Lombardi

Guardia
It has experienced a number of major earthquakes throughout its history that have devastated the town, and is considered within zone 1 of the Protezione Civile's seismic classification index, indicating very high seismicity.

Tidal triggering of earthquakes

may affect the frequency of earthquakesTides may also induce seismicity
Tidal triggering of earthquakes is the idea that tidal forces may induce seismicity.
