Description
Abstract
This database constains information on historical Idaho Idaho earthquakes derived from a search of the Advanced National Seismic System (ANSS) catalog. It contains earthquake epicenter location, magnitude, date, and time. The search was performed for dates between 1970 and 1/27/2011. The data are listed for each of Idaho's 44 counties.

Purpose
This dataset provides an Idaho earthquake catalog for each county in Idaho (not all counties have experienced historical earthquakes). It was developed to assist counties mitigate earthquake hazards.

Advanced National Seismic System (ANSS) Composite Earthquake Catalog
Search parameters used to extract Idaho data from the catalog:
·	catalog=ANSS 
·	start_time=1970/01/01,00:00:00 
·	end_time= 2011/01/27,11:59:59
·	minimum_latitude=42.0 
·	maximum_latitude=49.0 
·	minimum_longitude=-117.0 
·	maximum_longitude=-111.0 
·	minimum_magnitude=1 
·	maximum_magnitude=8 
·	event_type=E 
This yielded a dataset of earthquakes from 1970-2011/1/17 with minimum magnitude 1 and maximum magnitude = 8
Details regarding the fields in the dataset (Time, Lat, Lon, Depth, Mag, Magt etc. are given in
