Lombok is an island in West Nusa Tenggara province, Indonesia. It forms part of the chain of the Lesser Sunda Islands, with the Lombok Strait separating it from Bali to the west and the Alas Strait between it and Sumbawa to the east. It is roughly circular, with a "tail" (Sekotong Peninsula) to the southwest, about 70 kilometres across and a total area of about 4,514 square kilometres. The provincial capital and largest city on the island is Mataram.

Lombok is somewhat similar in size and density, and shares some cultural heritage with the neighboring island of Bali to the west. However, it is administratively part of West Nusa Tenggara, along with the larger and more sparsely populated island of Sumbawa to the east. Lombok is surrounded by a number of smaller islands locally called Gili.

The island is home to some 3.35 million Indonesians as recorded in the decennial 2014 census.

It caused over 550 deaths and more than 7000 were injured. Another Lombok earthquake occurred on 19 August 2018, killing 13 people and damaging 1800 buildings.

TOURISM

Public Ferries depart from Padang Bai (Southeast Bali) and Lembar (Southwest Lombok) every hour, taking a minimum of 4–5 hours make the crossing in either direction. 

Tourism is an important source of income on Lombok.  The most developed tourism area of the island is on the west coast of the island and is centered about the township of Senggigi. Direct fast boat services make a direct connection to the Gili islands. The Gili islands provide both a lay-back backpacker's retreat and a high-class resort destination.
