Downloads records of earth quakes from the USGS Earthquake Catalog
Usage
get_earthquakes(
start_time = today() - 30,
end_time = NULL,
min_magnitude = NULL,
base_url = "https://earthquake.usgs.gov/fdsnws/event/1/query"
)Arguments
- start_time
character string specifying the start date for the records in the form 'yyyy-mm-dd'
- end_time
character string specifying the end date for the records in the form 'yyyy-mm-dd'
- min_magnitude
numeric quantity specifying the minimum magnitude considered for a record
- base_url

Value
data frame of earth quake records. Detailed information on each of the variables can be found as part of the [USGS ComCat Documentation](https://earthquake.usgs.gov/data/comcat/index.php). By default, data for the last 30 days is requested from the archive. This is similar data to what USGS provides as `All Earthquakes` for the past 30 days in their spreadsheet/csv feed at https://earthquake.usgs.gov/earthquakes/feed/v1.0/csv.php
