RT : In 1927 Anak Krakatau (Child of Krakatoa), emerged from the 1883 Krakatau eruption and resulting caldera. It is the site of the current eruption that triggered the landslide that caused the tsunami

Out of curiosity, is there any drawback before the first wave, like there is when there is an earthquake tsunami?

A is type of surface wave; a combination transverse &longitudinal wave Each "wave" hits land is actually the crest of transverse wave; the drawback is when trough occurs on the transverse wave The longitudinal part gives an increase of water & pushes water mass forward

We would assume those near the shorelines would be affected. Those in open water would not feel much of a difference, thought it really depends on how close to the surface. Surface plankton would be pulled along, but not any great distance. Deep sea floor wouldn;t feel much.

News reports say the tsunami coincided with a lunar tidal wave. What impact will a tidal wave have on the tsunami?

Good question. Actually it was that high tide was in the harbor at the time, so this allowed for more volume of water to be involved in the tsunami So it wasn;t "adding of waves" as much as amount of water that aided the tsunami to grow larger

Anak Krakatau is a tiny island and a volcano as well. The landslide probably fell into the -200m deep 1883 caldera next to it and caused tsunami ? Could the entire volcano collapse and fill the main vent along with seawater ? The next big bang ?

Not sure on the 1883 eruption, will have to research Closing of a vent in cinder cone volcanoes is not a large deal, as their vents tend to be temporary, and solidify after each eruption. the next eruption works its way through the next weak part of the volcano. Normal.
