Abstract
This report of the survey of the marine resources at Halape was conducted July 17-23, 1975. Since that time the area has been severely disturbed by natural phenomena. The November 29, 1975 earthquake, (Richter Scale magnitude 8.4), generated a small tsunami which claimed the lives of two people and also severely disturbed the marine flora and fauna at Halape. Many animals and some plant material were either crushed or left stranded on land. However, this destruction was minor compared with the gross change in the habitat brought about by the land subsidence during the earthquake and in the following weeks. The land in the Halape region has sunk approximately eleven feet. The benthic environment in the area will not recover for some years as the newly submerged land surface is colonized and the previously submerged regions adapt and change in response to their greater depth. Figures 1 and 2 illustrate the conditions at Halape before and after the earthquake. There was no volcanic activity in the Halape area. Though this report presents information about an area whose features have been radically altered by nature, the results contained herein are still of considerable significance for resource management purposes. The report is the first comprehensive qualitative inventory of marine organisms along the coastline of Hawaii Volcanoes National Park. As such it will form the basis for future resource inventory studies in the area and all consequent ecological studies that may be necessary for resource management. Some work on the colonization of the newly submerged coastline is already being sponsored by the CPSU UH.
