There is no definitive evidence that an eruption at one volcano can trigger an eruption at a volcano that's hundreds of kilometers/miles away or on a different continent. ... In some such cases, one eruption doesn't really "trigger" a nearby vent to erupt, but moving magma finds its way to the surface at multiple sites.
