About
This dataset provides essential information on earthquakes, including their magnitude, location, and frequency, as recorded by the United States Geological Survey (USGS) across the United States and surrounding areas. Understanding these seismic activities is crucial for deciphering their causes and for the prevention of damaging quakes. The data offers valuable insights for building a clearer picture of the potential dangers posed by seismic events.
Columns
The dataset is primarily available in two files,
usgs_current.csv and usgs_main.csv, both containing the following columns:- time: The time of the earthquake. (DateTime)
- latitude: The latitude of the earthquake. (Float)
- longitude: The longitude of the earthquake. (Float)
- depth: The depth of the earthquake. (Float)
- mag: The magnitude of the earthquake. (Float)
- magType: The type of magnitude measurement used. (String)
- nst: The number of seismic stations used to calculate the magnitude. (Integer)
- gap: The maximum angular distance between azimuthal gaps. (Float)
- dmin: The distance to the nearest station. (Float)
- rms: The root-mean-square travel time residual. (Float)
- net: The network detected. (String)
- updated: The time the earthquake was last updated. (DateTime)
- place: The location of the earthquake. (String)
- horizontalError: The horizontal error of the earthquake. (Float)
- depthError: The depth error of the earthquake. (Float)
- magError: The magnitude error of the earthquake. (Float)
- magNst: The number of seismic stations used to calculate the magnitude error. (Integer)
- status: The status of the earthquake (e.g., reviewed, automatic). (String)
- locationSource: The source of the location of the earthquake. (String)
- type: The type of event (e.g., earthquake, quarry blast). (String)
- magSource: The source of the magnitude. (String)
Distribution
This dataset is provided in CSV format. The
usgs_current.csv file, for instance, is approximately 35.41 kB and consists of 22 columns. While specific numbers for rows/records are not explicitly stated for the entire dataset, the usgs_current.csv sample indicates 183 records are typically present for most fields, with some columns having fewer valid entries due to missing data.Usage
This dataset is ideally suited for geophysical research and analysis related to seismic activity. Key use cases include:
- Uncovering geophysical insights about earthquakes.
- Generating earthquake hazard maps to pinpoint seismic activity and risk levels in different regions.
- Developing predictive models for earthquake magnitude and probability of occurrence, based on geographic characteristics, historical seismic data, and observed patterns.
- Conducting analysis to identify correlations between geological features, human activities, and seismic events to better understand their causes and effects.
Coverage
The dataset focuses on earthquakes occurring across the United States and its surrounding areas. The time range for the
usgs_current.csv sample spans from 11th December 2022 to 13th December 2022. Latitude values range from approximately -22.4 to 65.4, longitude from -179 to 160, and earthquake depths from -0.26 to 577 units. Magnitude values range from -0.1 to 5.5.License
