After several weeks with no noteworthy seismic activity, the West Pacific roared back to life this week with a M7.2 earthquake in Vanuatu, and now we have reports of a new eruption in Indonesia at Mount Rinjani volcano.
This new unrest follows multiple weeks of silence when it comes to earthquakes, and volcanic eruptions.
A full earthquake forecast was issued for the West Pacific on October 20, 2015. The forecast called for new large movement to begin , additionally the progression of earthquakes across the West Pacific was discussed. See the forecast video here:

The threat of eruptions in Indonesia always follows the deep earthquake activity in the West Pacific, and shallow larger earthquakes.
First we see deep movement occur below the Pacific plate, then we see shallower larger earthquakes strike the areas adjacent to the deep movement, then (ultimately) we see the other areas adjacent to the large earthquake show volcanic activity, or large additional compensation earthquakes.

Lombok’s Mount Rinjani Closed as Lesser Volcano Erupts
“Jakarta. Authorities in West Nusa Tenggara have closed off the Rinjani National Park to the public after a volcano in the area erupted on Sunday morning.
Mount Barujari, located in the crater lake of Segara Anak, just east of the better-known Mount Rinjani, erupted at 10:45 a.m. local time, spewing material some 200 meters into the air, several media outlets reported.
Rinjani observation post chief Mutaharlin told Tempo that officials had evacuated hundreds of climbers and Hindu worshipers planning to perform a religious ceremony at the lake.
Barujari, part of the same volcanic system as Rinjani, which towers at an elevation of 3,700 meters above sea level, was first formed from a 1944 explosion of the main volcano.
An eruption in 1994 further developed the Barujari volcano, which now rises to an elevation of 2,300 meters above sea level.”
