Scientists drilled into the Japan Trench to study the fault zone that caused the 2011 Tōhoku earthquake, collecting sediment cores to understand earthquake triggers and improve future hazard assessments, with ongoing monitoring to observe fault evolution over time.
Geologists aboard the JOIDES Resolution ship have drilled down to 1,000 meters below the sea floor to collect mantle rock samples from beneath the Lost City Hydrothermal Field. The samples are expected to provide new insights into the composition and structure of the mantle, as well as processes that take place within it. The team has already sampled mantle rock that has never melted into magma, but some geophysicists argue that the samples show signs of seawater influence and should be termed deep crust rather than mantle.
