It looks like the banyan tree may have survived and even if the main tree has to be taken down for safety there are likely underground shoots that will come back in time.
This presents Lahaina with an opportunity to rebuild in a way they never could before, hopefully preserving the essential character of the town while making the utilities more resilient and the buildings more robust.
What really disturbs me are the reports that the civil defense or emergency management sirens didn't go off. The death toll is likely where it is (89 the last time I checked and probably going up) because residents didn't get a warning. My father worked for Civil Defense when he retired from the Air Force and I don't believe a situation with inoperative sirens would have been tolerated back then. We heard them monthly like clockwork in Honolulu in the 70s and 80s; Lahaina is seaside and those sirens are needed for tsunami warning (among other things). I hope the reports are wrong and that people just didn't hear them because they were isolated in their air-conditioned and sound-proofed rooms or plugged into their iBuds.
