WebJan 1, 2024 · These techniques are based on the idea that objects which form a dense region should be grouped together into one cluster. One of the most widely used density-based clustering algorithms, i.e., the DBSCAN (Density-Based Spatial Clustering of Applications with Noise), was originally proposed in Ester et al. (1996). WebIn general: A cluster is any group of earthquakes of similar type and magnitude in a given area over a period of months, but not including aftershocks (resulting from marginal adjustments to a main shock, and steadily diminishing in size and frequency), while a swarm is an elevated level of low and moderate magnitude events in a period of ...
