Long-lived eddies are an important part of the ocean circulation. Here a dataset for studying eddies in the Gulf of Mexico is created through the analysis of trajectories of drifting instruments. The method involves the identification of quasi-periodic signals, characteristic of particles trapped in eddies, from the displacement records, followed by the creation of a measure of statistical significance. It is expected that this dataset will be of use to other authors studying this region.

Earthquakes have triggered numerous landslides, and much progress has been made in their study. But, so far, the dynamic behavior of slope disasters still lacks understanding, such as whether there is a definite energy and spacial distribution of earthquake-induced landslides or whether giant landslides and small landslides follow different formation mechanisms. In this study, we attempt to answer these questions from the point of view of the self-organized critical (SOC) theory.
