I read with interest the recent paper entitled ‘Geophysical Predictions: Overview and Recommendations’ (July 1 978 EOS, pp. 710–718).

Of particular interest to me was the location of a volcanic eruption center in central-northwestern Venezuela (Figure 4). In this area, to my knowledge, there is no volcanic activity, and there has not been, at least in the Quaternary and possibly as far back as the Late Cretaceous. There are only minor fumarolic shows which are located along the Boconó and other active faults. Between the Eastern Cordillera (Colombia)-Sierra de Perijá (Venezuela) and the Lesser Antilles, no tectonic environment conducive to volcanism is found.
