The rumbling Ring of Fire putting parts of Asia in peril

The horseshoe-shaped string of active volcanoes bounding the Pacific Ocean has lived up to its Ring of Fire name in the past month, sparking mass evacuations in Indonesia and Vanuatu and now setting parts of southwestern Japan on edge.
The 450 or so volcanoes that make up the Pacific Ring of Fire are an outline of where the massive Pacific Plate is grinding against other plates that form the Earth’s crust, creating a 40,000km-long zone prone to frequent earthquakes and eruptions.

The Shinmoedake volcano in southwestern Japan started erupting on Wednesday for the first time in about six years.
According to Japanese broadcaster TBS, an ash plume rose 1,700m from the crater on Thursday and ash fell on cities and towns in Miyazaki prefecture.
Videos showed students wearing helmets and masks on their way to an junior school at the foot of Shinmoedake.
