EQ Catalog Download¶
The “EQ Catalog Download” widget allows users to acquire earthquake data from two Open Data APIs: USGS (United States Geological Survey) and the Chile Sismology website. This tool enables precise data extraction based on user-defined parameters such as location, time period, and minimum magnitude.
Data Source Options¶
USGS: Provides global earthquake data, including parameters like magnitude, location, and depth.
Chile Sismology: Offers detailed seismic data specifically for Chile, ideal for regional studies.
Configuration Parameters¶
The widget offers a variety of configuration options to customize the data acquisition:
Data Source: Choose between “USGS” or “Chile Sismology”.
Time Period:
Start Date: Select the starting date for the data acquisition.
End Date: Specify the ending date for the data acquisition. Ensure that the end date is after the start date.
Minimum Magnitude: Define the minimum earthquake magnitude to filter events (range: 0.0 to 10.0).
Location Options:¶
By Rectangle: Define a bounding box with:
Min Latitude
Max Latitude
Min Longitude
Max Longitude
By Circle: Provide the central coordinates (Latitude, Longitude) and the radius (Max positive Radius in km).
Outputs¶
Data: A table containing earthquake events with attributes such as magnitude, location, depth, and timestamp.
Configuration Table: A summary of the user-defined parameters used for data acquisition.
Usage Tips¶
For precise results, adjust the magnitude and location parameters carefully.
Utilize the “Generate” button to initiate data acquisition, and the “Reset” button to clear configurations and start anew.
When using “Chile Sismology”, verify that the chosen coordinates are within the country’s geographical limits.
