The Mariana Trench itself is not an active geological feature in terms of eruptions or surface activity, as it is primarily a deep-sea trench formed by tectonic processes. However, the area is seismically active due to the subduction of the Pacific Plate beneath the Mariana Plate. Significant seismic events, such as earthquakes, occur in this region, but there isn't a specific "last active" date for the trench itself. Instead, it is constantly shaped by ongoing tectonic activity.
