Global Earthquake Archive

<p><span>The US Geological Survey maintains official records of earthquake
activity from around the globe. This layer displays all earthquakes since 1900
with a magnitude 4.0 or greater, and updates once a day. For more recent activity,
please see the <a href='https://arcgis.com/home/item.html?id=9e2f2b544c954fda9cd13b7f3e6eebce' rel='nofollow ugc'>Recent

This change allows users to support analytics and export for local client consumption. Depth can be leveraged by using the elevation field. Anticipating online enhancements, we set the custom projection to support the change in the Z value range. Refined the schema to improve efficiency. Layer has been Time-Enabled to allow for Time Series display, but disabled by default. Data download has now been enabled.</li><li><b>May 5, 2023: </b>Updated service with four duplicated fields to match the Recent Earthquake Service's data schema. Depth, Event Time, Event Type, TZ are the duplicated fields. </li></ul></div>
