I watched this fascinating a.b.c. programme also. The volcano which worries your mum is Anak Krakatau. When it's parent volcano Krakatau blew itself up in 1883 one of the effects was a tsunami which drowned 90% of the recorded 36,000 people who died.
Tell your mum in Indonesia thirty-one volcanoes are continuously monitored from 35 volcano observatories by Volcanological Survey of Indonesia. Two of these observatories monitor the activities of Anak Krakatau.
