Earthquake Centers - United States Geological Survey Earthquake Hazards Program
type: Dataset
description: The USGS Earthquake Hazards Program of the U.S. Geological Survey (USGS) is part of the National Earthquake Hazards Reduction Program (NEHRP) led by the National Institute of Standards and Technology (NIST). The USGS role in NEHRP is to provide Earth sciences information and products for earthquake loss reduction. The goals of the USGS' Earthquake Hazards Program are: * Improve earthquake hazard identification and risk assessment methods and their use; * Maintain and improve comprehensive earthquake monitoring in the United States with focus on "real-time" systems in urban areas; * Improve the understanding of earthquakes occurrence and their effects and consequences. This dataset can be used to provide and apply relevant earthquake science information and knowledge for reducing deaths, injuries, and property damage from earthquakes through understanding of their characteristics and effects and by providing the information and knowledge needed to mitigate these losses.

  description: GeoJSON file for earthquake centers over a magnitude of 4.5 for the Pacific Islands Region for years 2000-2004. Data are derived from the ANSS Comprehensive Earthquake Catalog (ComCat). ComCat contains earthquake source parameters (e.g. hypocenters, magnitudes, phase picks and amplitudes) and other products (e.g. moment tensor solutions, macroseismic information, tectonic summaries, maps) produced by contributing seismic networks. Fields are defined below: alert Data Type: String Typical Values: “green”, “yellow”, “orange”, “red”. Description: The alert level from the PAGER earthquake impact scale. cdi Data Type: Decimal Typical Values: [0.0, 10.0] Description: The maximum reported intensity for the event. Computed by DYFI. While typically reported as a roman numeral, for the purposes of this API, intensity is expected as the decimal equivalent of the roman numeral. Learn more about magnitude vs. intensity. code Data Type: String Typical Values: "2013lgaz", "c000f1jy", "71935551" Description: An identifying code assigned by - and unique from - the corresponding source for the event. Depth Data Type: Decimal Typical Values: [0, 1000] Description: Depth of the event in kilometers. Additional Information: The depth where the earthquake begins to rupture. This depth may be relative to the WGS84 geoid, mean sea-level, or the average elevation of the seismic stations which provided arrival-time data for the earthquake location. The choice of reference depth is dependent on the method used to locate the earthquake, which varies by seismic network. Since ComCat includes data from many different seismic networks, the process for determining the depth is different for different events. The depth is the least-constrained parameter in the earthquake location, and the error bars are generally larger than the variation due to different depth determination methods. Sometimes when depth is poorly constrained by available seismic data, the location program will set the depth at a fi…
