There was a great deal of criticism in the press about the inconvenience and there was growing pressure to improve the existing U. Tsunami Warning System, administered by the Honolulu Observatory (now known as the Pacific Tsunami Warning Center, or PTWC).
In 1964, the construction of the Hawaii Institute of Geophysics (HIG) building was completed at the University of Hawaii campus in Manoa Valley. George Woollard arrived from the University of Wisconsin to assume the HIG Directorship.
Finding the thinnest part of the earth's crust to drill the MOHOLE became one of the major research projects.
The Geology, Oceanography and Geophysics Departments came under the umbrella of HIG at that time.
On October 13 and 19, 1963, two Saturdays apart, the Honolulu Observatory (HO) of the U. Coast and Geodetic Survey (USCGS), issued tsunami warnings for earthquakes off Hokkaido, Japan.
No tsunamis of significance occurred in Hawaii and the public perceived that the tsunami warnings were faulty.
Together with Fred Duennebier they worked on T-phase sources, their spectral variations, and their use in earthquake epicenter determinations.
Gus Furumoto worked on ionospheric recordings of Rayleigh waves and the seismicity of Hawaii.
Gordon Groves, Bob Harvey and Eddie Bernard worked on the dissipation of tsunamis, their spectral decomposition and the non-linear behavior at islands and continental coastlines.
Bill Adams, George Pararas-Carayannis and others, continued to work on tsunami anomalies and precursory seismic phenomena as predictors of potential tsunami inundation.
