In that study which involved 19,065 people during a 15-year period, rates of infidelity among men were found to have risen from 20 to 28%, and rates for women, 5% to 15%.
It is one of the most active Chilean volcanoes, with 59 documented eruptions since 1558, according to the European Space Agency.
The snow-covered volcano is one of only a small number of volcanoes around the world with an active lava lake.
In January, an eruption at Mount Agung in Indonesia disrupted the flights of thousands of holidaymakers.
At the start of May, Hawaii’s Kilauea volcano began spewing lava and smoke, sparking mass evacuations and damaging vital infrastructure.
Results, however, vary year by year, and also by age-group surveyed.
For example, one study conducted by the University of Washington, Seattle found slightly, or significantly higher rates of infidelity for populations under 35, or older than 60.
In general, national surveys conducted in the early 1990s reported that between 15–25% of married Americans reported having extramarital affairs.
People who had stronger sexual interests, more permissive sexual values, lower subjective satisfaction with their partner, weaker network ties to their partner, and greater sexual opportunities were more likely to be unfaithful.
Scientists have discovered that the increase in ice coverage correlated with a decrease in volcanic eruptions in the country, and that the same was true in reverse: when the ice depleted, the number of eruptions increased.
Current trends in climate change indicate that Oraefajokull, Iceland’s largest active volcano, may be heading for an eruption, a theory backed by increased tectonic activity.
Geophysicist Pall Einarsson says the increased number of earthquakes at the site “are telling us that there’s plenty of reason to monitor the course of events carefully”.
