[2005 War Of The Worlds] why did the first tripod keep switching between people buster and building buster shots?

The tripod starts shooting people but then it starts firing blasts powerful enough to destroy buildings. Why not open with that? And why keep switching back to the peewee people buster shots if you have shots that can destroy buildings?

It's tough to say without knowing more about Martian weaponry or combat doctrine. There may be a difference in charge or cooling cycles that encourages switching back and forth between fire modes (compare a main battle tank crew switching between the main gun and a co-axial 50 cal as appropriate targets present themselves), or it may be part of a psychological warfare plan to keep the enemy off-balance about the true maximum firepower of any given tripod.
