    Notes: Abstract Earthquake swarms in California are often localized to areas within dextral offsets in the linear trend in active fault strands, suggesting a relation between earthquake swarms and local crustal spreading. Local crustal spereading is required by the geometry of dextral offsets when, as in the San Andreas system, faults have dominantly strike-slip motion with right-lateral displacement. Three clear examples of this relation occur in the Imperial Valley, Coso Hot Springs, and the Danville region, all in California. The first two of these areas are known for their Holocene volcanism and geothermal potential, which is consistent with crustal spreading and magmatic intrusion. The third example, however, shows no evidence for volcanism or geothermal activity at the surface.

    Description / Table of Contents: Summary An organization for data-processing in phyto-sociology and plant ccology is deseribed. A good preparation by means of standard sheets for collecting and codifying information from the field is emphasized (Fig. 1). Fig. 2–5 present the arrangement and the logical sequence of the different methods of data analysis (ecological profiles, factor analysis,...) which allows the study of the relations between environmental and floristical variables, in a quick and efficient way. Cooperation with the Ecothèque méditerranéene at Montpellier is both necessary and fruitful. One example is presented using the selection ‘e’ of 58 relevés of salt marsh vegetation retained by the Working Group for Data-Processing of the International Society for Vegetation Science.
    Notes: Résumé Les auteurs proposent ici une organisation du traitement des données en phytosociologie et phyto-écologie. L'organisation repose sur un système bien développé pour rassembler et codifier l'information des reléves. (fig.1). Un ordinogramme (Fig. 2–5) présente l'agencement et l'enchaînement des différentes méthodes d'analyse des données (profils écologiques, analyse factorielle, ...) qui permettent d'étudier les relations entre variables du milieu et variables floristiques. La conception de l'enchaînement des fichiers et des programmes de traitement permet d'aboutir assez rapidement aux résultats, facilitant ainsi la tâche du phytosociologue et du phyto-écologue. Ce travail a été réalisé en commun entre le C.E.P.E. Louis Emberger et l'Ecothèque méditerranéenne conduisant à une coopération nécessaire et utile. Une exemple est traité utilissant la sélection ‘e’ de 58 relevés de milieux salés, sélection retenue par le groupe de travail ‘traitement des données en phytosociologie’ de l'Association internationale de phytosociologie.
