This follows the eruption of a sleeping volcano, which erupted at least 16 hours ago.
Kopar councillor Tom Kelly told this newsroom that the boats were sent out as soon as they noticed that something was wrong. However, the boats are yet to return.
Kopar is the nearest island – at least a thirty-minute boat ride to Kadovar.
Kelly said at the moment, thick clouds can be seen from the island, and the clouds are darker and increasing at an alarming rate.
He said they are yet to receive a response from the disaster office or government.
