There are several islands that show trails of volcanic activities in Lombok Island mainly on its western part. Batubolong Beach is located in the well-known Senggigi Beach with its sands graining from abraded volcanic rocks. There is a cape consisted of andesite-basalan lava with sheeting joint located on top of volcanic breccias. In this location lies Batubolong Temple as one of shrines for Hindu in Lombok Island.

Andesit-basalan Lava and its Sheeting Joint

A hole formed by abrasion process

Malimbu Beach is a bay-shaped beach with its northern border being TanjungSerombong, which was formed by volcanic rocks of breccia and sheeting joints lava. Abrasion process causes a part of TanjungSerombong to cut making a small hill in a form similar to a temple, which is separated from the main land. The process also successfully created a perforation in there locally named Batubolong (Batu: rock, bolong: perforated). Its sands are white, made from abraded limestone coral sediment. These whole morphological beauties can be seen from TanjungRumbeh/Malimbu or TanjungBlambanan/Nipah.

Kerandangan Beach has geological phenomenon in the form of pillow lava contaminated by volcanic breccias. Pillow lava shows sheeting joints and vesicular.
