A geologist observes an ash plume rising above the crater of Parícutin on 22 March 1944, as seen from 1 km SW at Mesa de Cocjarao. During March 1944 the eruptive activity ranged from small ash plumes accompanied by deep rumbling to large but almost soundless ash plumes, as was true with the plume shown here.
