The threats to Elephanta Caves have been identified as the following : developmental pressures ( mainly due to its location within the Mumbai harbour ) , anthropogenic pressure due to growth of population of the communities residing on the island , industrial growth of the port facilities close to the island , no risk preparedness plan to address natural calamities such as earthquake , cyclones and terrorist attacks , unsustainable tourism and tourist facilities on the island , and poor management of the heritage monument . Preservation of Elephanta Island as a whole with its monuments has been ensured both through legislation and by physical restoration of the caves and its sculptures . The basic legislations enacted are : The Ancient Monuments and Archaeological Sites and Remains Act of 1958 and Rules ( 1959 ) ; The Elephanta Island ( Protected Monument ) Rules of 1957 , which prohibits mining , quarrying , blasting , excavation and other operations near the monument ; the Antiquities and Art Treasures Act promulgated in 1972 with its Rules promulgated in 1973 ; a Notification issued in 1985 declaring the entire island and a 1 @-@ kilometre ( 0 @.@ 62 mi ) area from the shore as a prohibited area  ; a series of Maharashtra State Government environmental acts protecting the site ; the 1966 Regional and Town Planning Act ; and the 1995 Heritage Regulations for Greater Bombay . The Archaeological Survey of India ( ASI ) , Aurangabad Circle , on the basis of the above legislation and rules , maintain and manage the monuments . The physical measures undertaken for conservation cover include stabilisation of the rock face , construction of supports to the cave structures where pillars have collapsed , and consolidation of cave floors and construction of a parapet wall surrounding the site . In addition , visitor facilities at the site have been upgraded ( such as toilet facilities , railing construction , pathways , and a flight of steps from the jetty to the caves ) . An on @-@ site museum has been established and a conservation plan has been put in place . Overall , conservation of the property is stated to be good . The site receives approximately 25 @,@ 000 visitors per month . Public information brochures are also available at the venue of the monuments . During the World Heritage Day on 18 April and World Heritage Week between 19 and 25 November there are special events held at the caves . Another popular event organised is an annual traditional dance festival that attracts many visitors . After declaring the caves a World Heritage Site , UNESCO granted $ 100 @,@ 000 to document the site 's history and draw up a site plan . A part of the grant was used for conservation of the caves . Based on assessments by UNESCO , management plans include : better communication and collaboration between the ASI , on @-@ site staff , and other responsible government departments ; improved public information and awareness programs ; monitoring environmental impact of tourists on the cave and island environment ; greater attention to the maintenance of the rocks to address water leakages into the caves ; and daily monitoring of both structural and chemical conservation measures . The Indian National Trust for Art and Cultural Heritage ( INTACH ) is also involved with the Archaeological Survey of India in improving the local conditions at the cave site . A book has been published jointly by UNESCO , INTACH and the Government of India which presents a comprehensive site plan for restoration and a brief history of each sculpture constructed inside the caves .
