Similarly, the late June eruption of Cotopaxi aligns with 1877’s cold August — but there is no other reported evidence for related cooling in northern Norway after this eruption. This blue ...

Some studies have also found links between the cold Norwegian summer of 1877 and the eruption of Cotopaxi in Ecuador. But researchers say “there is no other evidence” to link the volcanic ...

The scientists identified blue rings caused by particularly cold summers in 1877 and 1902, which could potentially have been caused by the eruptions of far-off volcanoes Cotopaxi in Ecuador and Mount ...

Esa Hiltula/Daniel Jara/Getty The cooling may be linked to major volcanic eruptions: Mount Pelée on Martinique in 1902 and Cotopaxi in Ecuador in 1877. These eruptions likely cast a volcanic ...

While the blue rings from 1877 align with a June eruption of Cotopaxi in Ecuador, the blue rings from 1902 align with a May eruption of Mount Pelée in Martinique. Mostly observed in latewood, which ...

so a full eruption is expected anytime soon. The Cotopaxi is one of the most active volcanoes in Ecuador. At 5,897 meters above sea level, it is the second-highest peak in the country and together ...
