Why are so many volcanoes erupting around the world?
There are theories that volcanic eruptions are on the rise. A 2014 study found that changes in the speed of the earth’s rotation, caused by factors including the gravitational pull of the sun and the moon, lead to periods of increased volcanic activity. Three quarters of the world’s volcanoes can be found here.
Why are volcanic eruptions increasing?
The apparent increase in activity reflects increases in populations living near volcanoes to observe eruptions and improvements in communication technologies to report those eruptions. Graph showing the number of volcanoes reported to have been active each year since 1800 CE.

What causes a volcano to form and then erupt?
To conclude, volcanoes are mainly formed in subduction zones or magmatic hotspots. And the volcanic eruptions are caused by the upthrust of magma, the pressure created by gases, and the influx of new magma in existing magma chambers.
