Qaraxii ugu dambeeyay ee Rinjani wuxuu ka dhacay bishii Sebtember 2016 Gunung Barujari. Sanadkii 2010-kii ayaa waxaa la sheegay in dambas uu hawada ka soo baxay Barujari Cone oo ku yaalla Rinjani's caldera lake of Segara Anak. Lava ayaa ku qulqulay harada caldera, kor u qaadista heerkulkeeda, halka dambasku uu waxyeelo u geystay dalagyada dhaadheer ee Rinjani. Buurta iyo harada godkeeda, Segara Anak (ilmaha badda), waxaa ilaaliya Beerta Qaranka ee Gunung Rinjani oo la aasaasay 1997. Caddaymihii ugu danbeeyay waxay tilmaamayaan buurta Samalas, oo hada kaliya ka hartay caldera, inay aheyd halka uu ka yimid
1257 Qaraxii Samalas, oo ka mid ahaa qaraxyadii ugu waaweynaa ee taariikhda la diiwaan geliyo, kaas oo sababay isbeddelada cimilada adduunka oo dhan.
