Mount Rinjani

Mount Rinjani (Indonesian: Gunung Rinjani) is an active volcano in Indonesia on the island of Lombok. Administratively the mountain is in the Regency of North Lombok, West Nusa Tenggara (Indonesian: Nusa Tenggara Barat, NTB). It rises to 3,726 metres (12,224 ft), making it the second highest volcano in Indonesia.  It is also the highest point in the Indonesian province of West Nusa Tenggara.

Adjacent to the volcano is a 6-by-8.5-kilometre (3.7 by 5.3 mi) caldera, which is filled partially by the crater lake known as Segara Anak or Anak Laut (Child of the Sea), due to the color of its water, as blue as the sea (laut).  This lake is approximately 2,000 metres (6,600 ft) above sea level and estimated to be about 200 metres (660 ft) deep; the caldera also contains hot springs. The lake and mountain are sacred to the Sasak people and Hindus, and are the site of religious rituals. UNESCO made Mount Rinjani Caldera a part of the Global Geoparks Network in April 2018.

Mount Rinjani

Rinjani Volcano Observatory has detected an increase in volcanic tremor activity at Rinjani Volcano in Lombok Island, West Nusa Tenggara province. This increase is observed in the past 3 hours. The recorded tremor amplitudes vary around 5.0-24.0 mm while the background is around 0.5-1.00 mm. However, until now, no eruption plume could be observed from the observatory.

Volcanic ash is not visible/observed.

Volcanic tremors are still recorded until this report is made. This signature is relatively similar with the past eruption on September 27, 2016 06:45 UTC which was characterized by explosive activity (volcanic bombs and thick ashes) as well as effusive style (lava flow through the north-northeast direction on the Barujari flank and reached the caldera lake) styles.
