Rescue efforts are being hampered by blocked roads but heavy lifting equipment is being transported to badly hit areas to help search for victims. Indonesia's disaster mitigation agency said, the death toll following the tsunami has risen to at least 373.
In a statement, agency spokesman Sutopo Purwo Nugroho said, more than 1,400 people are injured, while 128 remain missing.
The Indonesian Medical Association of the worst-affected Banten region said that it sent doctors, medical supplies and equipments.
Coastal residents near the volcano have been warned to keep away from beaches amid fears it could trigger a new tsunami.
Hundreds of buildings were destroyed by the wave, which hit the coast of southern Sumatra and the western tip of Java on Saturday after a volcano known as the "child" of the legendary Krakatoa, erupted. It was the second deadly tsunami to hit seismically active Indonesia this year.
A powerful earthquake triggered a tsunami that hit Sulawesi island in September.
