Japanese Trench

The Japanese Trench is the last named stretch of an underwater route Jonas Taylor proposes Angel may be following toward the Mariana Trench. In his explanation, the trench turns a shark’s long-distance journey into a possible response to the Pacific’s seismic geography, though the route remains a hypothesis rather than a confirmed account of Angel’s movements.

Place in the Proposed Route

Jonas argues that sharks can use the Earth’s magnetic field and seismic vibrations along fault lines to orient themselves over long distances. He believes Angel bypassed the Bering Sea and continued southwest by following subtle vibrations from the Aleutian Trench. On the route he traces, the Aleutian Trench leads across the North Pacific toward the Kamchatka Trench and Kuril Trench; those trenches continue southwest past the Kuril Islands before becoming the Japanese Trench. Jonas identifies this sequence as part of the Ring of Fire.

Connection to the Mariana Trench

In Jonas’s account, the Japanese Trench empties into the Mariana Trench, which he describes as the species’ home for a million years or more. The Japanese Trench therefore serves as the proposed final passage in a chain connecting Angel’s movements across the North Pacific with the deep-sea habitat from which her species came. The explanation builds on the earlier journey of Angel’s mother, who escaped the Mariana Trench four years before and moved east along the Hawaiian island chain, then north beside the Central American coast to Monterey Canyon—locations Jonas also associates with the Ring of Fire.

Interpretation and Uncertainty

The route offers Jonas an alternative to the idea that Angel is following whale migration. Mac likens the trench system to an underwater highway, but Captain Morgan remains unconvinced that seismic orientation is the explanation. The Japanese Trench’s significance in the discussion thus rests on both geography and uncertainty: it completes Jonas’s proposed path, while the competing possibility of cetacean migration leaves Angel’s destination unresolved.
