This week, a potential lahar hazard developed at the erupting Mayon volcano. Meanwhile, a series of unusual earthquake swarms at Kilauea threatens a potential change in its eruptive series. And, in Alaska, the alert level of the Pavlof volcano was raised due to a detected series of long period earthquakes. Today's video will discuss these stories through the opinion and analysis of a geologist and list the 45 world volcanoes that are actively erupting. Note: This video's thumbnail image displays an eruption of the Mayon volcano from a prior year. Note #2: There is no guarantee that one or more lahars will occur on the Mayon volcano, there is just a possibility of such.
