Answer: Some geographic areas have obvious natural advantages that result in cluster formation. For example, proximity to a large port will attract exporting firms or areas rich in minerals will attract clusters of mining firms. In addition, there are three well-established reasons why firms choose locate in close proximity. The cost of transporting goods is reduced when firms are located close to their customers or suppliers. Input suppliers can exploit economies of scale in large clusters of downstream firms who, in turn, benefit from timely delivery and lower inventory costs.
Explanation: There are various types of clustering are that include:
^ Connectivity-based Clustering (Hierarchical clustering)
^ Centroids-based Clustering (Partitioning methods)
^ Distribution-based Clustering.
^ Density-based Clustering (Model-based methods)
^ Fuzzy Clustering.
^ Constraint-based (Supervised Clustering)

Answer:
The correct answer is: a) it relies on testimony from people.
Explanation:
The Mercalli intensity scale, unlike the Richter scale, does not directly measure the energy of an earthquake. Rather, it takes into account the damage and effects that the earthquake caused. When there is little damage, it relies on the testimony of people who felt the earthquake, which may vary and is ultimately subjective to people's perception.
The Mercalli Intensity Scale ranges from "Not felt" to "Catastrophic" going through 12 scale intensities.
