文摘

We document seismic indicators of gas hydrate and related gas and fluid flow. We document submarine slope failure-features, such as scars, MTDs, and glide planes. We calculated present-day gas hydrate stability zone using in-situ physical properties. A close spatial relationship occurs between slope failures and fluid flow features and the GHSZ.
