The level of seismicity of G. Rinjani after the first eruption dated on October 25, 2015 showed an increase mainly in the amplitude of tremor. This one was recorded continuously from November 2, 2015 23:00 until November 5, 2015 at 18:00. Direct field observations on November 3 to 4, 2015 indicate that earthquakes are correlated with the constant eruptions occurring on the cone of the G. Barujari.
Visually, the G. Rinjani surface activity after the eruption of October 25, 2015, shows an observed increasing. Emission of smoke was observed coming out of the crater continuously with a maximum height of 2000 m above the G. Barujari.
G. Barujari products ash emissions, pyroclastic impact on the cone of G. Barujari and lava flows that descend to the north of the crater. The threat of immediate danger as pyroclastic flows and lava emissions are still present in the caldera of Rinjani.
Until today the eruption still has the potential to continue as indicated by the tremor, recorded continuously.
Based on the visual and instrumental analysis as well as considering the potential threat of danger, November 5, 2015 at 18:00, Mount Rinjani is registered at Level II activity level (Alert / Waspada).
Intensive surveillance is conducted to assess the level of activity on G. Rinjani.
The communities around Mount Rinjani and visitors / tourists are not allowed to move or camp in G. Rinjani caldera and within a radius of 3 km around the crater of G. Barujari in G. Rinjani caldera.
If emission of ash, people should stay at home, and if they are outside the houses are encouraged to wear a mask to cover the nose and mouth and eye protection to prevent respiratory infections (ARI) and eye irritation.
