New drone technology was combined with satellite and ground-based data to improve volcanic gas flux monitoring at the remote Bagana Volcano in Papua New Guinea.
Mantle rocks in Papua New Guinea contain curious geochemical signatures that scientists have traditionally interpreted as evidence of billions-year-old melting. New evidence suggests otherwise.
Geologic and geomorphic observations of an active low-angle normal fault reveal a rolling-hinge mechanism accommodating the exhumation of a metamorphic core complex in Papua New Guinea.
When volcanic mountains slide into the sea, they trigger tsunamis. How big are these waves, and how far away can they do damage? Ritter Island provides some answers.
