It's a trend for the past two months at least. Volcanic activities (from the newsanyway) that began in Indonesia, then Vanuatu, and now an eruption in Japan.

Is it Possible for Global Warming , Current Weather Pattern (Increasing Intensity of Hurricanes), have any correlation to these Seismic Activities?
Is the overheating contributing to these movements?
