Overview

In overall, Indonesia is located in the area “ring of fire” in which prone to natural disasters ranging from the one coming from endogenic process i.e. earthquake and tsunami to the one coming from the interaction between endogenic and exogenic process i.e. landslide, erosion and drought.

East Java province is one of the most crowded provinces in Indonesia after West Java Province. Geographically, East Java Province is bordered by Java Sea in the north-ward, Bali Strain in the east-ward, Indian Ocean in the south-ward and Central Java Province in the west-ward.

In physiographic term, East Java province can be categorized into three zones: southern zone (plateaus), middle zone (volcanic mountains) and northern zone (fault zones) (www.en.wikipedia.org). Southern zone which is directly facing subduction zone between the India-Australian Plate and Eurasian Plate leading this zone prone to geological hazard i.e. earthquake and tsunami. The Middle zone has relative fertile land due to volcanic eruption while northern part consists of topographic Karsts that may lead to water shortage.

As one of central industrial developments in Indonesia East Java, Province has high demand of infrastructure and settlement area for supporting its economic activities. Thus, overpopulation and overdevelopment increase pressure to environment as well as triggering environmental degradation leading the vulnerability of the population due to the natural and manmade hazards that may occur in the area.

In order reduce the impact of disaster occurrence i.e. loss of lives, property damages and economic losses, stakeholders including all level of governments, non – government and community based organization should conduct disaster risk management involving several activities of prevention, preparedness, response, recovery, mitigation and risk reduction and rehabilitation.

Disaster risk management information system (DRMIS) is a system function as a useful basis for planning, monitoring, controlling and reporting activities due to the efforts of reducing disaster’s impact. Hopefully, DRMIS can give both spatial and statistical data related to disaster occurrences in the study area.
