Over the years HVO has attempted to maintain its scientific energy, enthusiasm, and insights by melding a permanent staff with a smaller cadre of rotating, research-oriented scientists. The observatory has about one rotating researcher for every four or five permanent staff. Rotating scientists generally stay 3-5 years.

What is often overlooked is that the largest and deadliest locally generated tsunami also occurred in the month of April.
