| This report summarizes early results of wide-ranging studies of the volcanic activity and eruptive products at Mount St. Helens in 1980 by the USGS, including some contributions by other participating government, university, and industry scientists. The papers collected here were mostly written in October and November, 1980, with some revisions and updating as late as January 1981. They accordingly constitute initial, in part preliminary, reports and interpretations of the 1980 activity; time constraints on publication have precluded full analysis and interpretation of some data, especially those related to the later events of 1980. More detailed discussions of some aspects of the volcanic activity summarized here can be expected in the future. -- Lipman and Mullineaux (eds.), 1981 |
