Weather station scripts - USGS earthquakes

They're free, but use at your own risk

The scripts referenced here are used in the operation of this weather station, and may be freely copied and used to support your station. Please note that you use these scripts at your own risk. No warranty is expressed or implied. I accept no liability for any damages that may ensue from their use.
You will need to configure them for your own particular weather station website.
RSS feed for Scripts Updates A RSS Feed is available to help keep you informed on updates to the scripts.

Many of these scripts are now available on GitHub at https://github.com/ktrue

If you find one or more of the scripts useful to you, please consider making a donation to help offset the routine expenses of operation of this website.
Thanks for your kind support!

A Version History is available -- check back from time to time to see if there are updates to scripts you have downloaded earlier. Announcements of version updates and new scripts are made on WXForum.net and Weather-Watch forums and saratogaWXPHP Twitter account as they become available.

PHP Scripts (run on webserver)

Recent nearby earthquakes (from USGS, NRC, BGS) PHP

Here in California, we're a bit sensitive to the earth moving (it happens a lot), so I wrote a PHP scripts to get, cache and reformat the last 7 days of earthquake information so it can be included on the website with links to additional info.

The output of these scripts is XHTML 1.0-Strict compliant. All of them use the same style for inclusion into your webpage as shown in the example below.

Note: Version 2.00 of the script replaced Google maps with Leaflet/OpenStreetMaps scripts, so you no longer need a Google API key (or any API key to use the 5 included maps with the script.
Version 3.00 adds two additional (free) maps: NatGeo and Delorme(Garmin) options. Also tectonic plates and/or faults can be displayed on the map. See the settings below for the geographical areas covered by the fault maps.

If you wish to use the OPTIONAL Mapbox.com tiles (terrain3, Satellite maps), you will need a Mapbox.com API key (called an "Access Token") which can be acquired (for free with 50K accesses usage/month) at:

https://www.mapbox.com/signup/?

in the quakes.php script you can put

$setMapboxAPIkey = '-replace-this-with-your-API-key-here-';

Note: if using the Saratoga template set, put a new entry in Settings.php

$SITE['mapboxAPIkey'] = '-replace-this-with-your-API-key-here-';

A Mapbox API key is OPTIONAL .. you do not need it to use maps from 5 included free map tile providers.

The USA/World earthquake script uses the new USGS GeoJSON feed for data and provides information on USA quakes of 1.0+ magnitude and Worldwide quakes of 4.0+ magnitude. This script is included in the AJAX/PHP Base-USA and Base-World template sets. Sample output with USA settings:

Earthquakes in the past 7 days of magnitude 2.0 or greater within 200 mi

The USGS GeoJSON earthquake script (V3.03 - 30-Jun-2020):
download .zip package [ see version history ]

This script loads the GeoJSON feed for all earthquakes in the last 7 days from the USGS. For the USA, magnitude 1.0+ quakes are available. For non-USA locations, the USGS only provides information on magnitude 4.0+ based on the data they receive from partner seismographic organizations. If you are installing the script for standalone use, do download the .ZIP package as it contains the graphics files needed for the Google Map. If you are using the AJAX/PHP template set (V3+), the script is already integrated into the Base-Canada, Base-USA, and Base-World templates.

For Base-World template users, the script is compatible with the language translation features of the template set. You may need to add to your language-LL.txt translation file the following entries (translated) in order to show the ouput in language LL.

The Canada earthquake script : demo and download [ see version history ]
Documentation on how to customize the script is in comments contained in the source. For anywhere in Canada, you just have to change $myLat and $myLong to your station's decimal latitude and longitude to see it work in your area. Defaults are for magnitude 2.0 (or greater) within a 500 km radius. This script uses data from Natural Resources Canada website and returns earthquake activity over the last 30 days. Version 1.03+ now provides both English and French display.

The UK earthquake script : demo and download [ see version history ]
Documentation on how to customize the script is in comments contained in the source. For anywhere in the United Kingdom, you just have to change $myLat and $myLong to your station's decimal latitude and longitude to see it work in your area. Defaults are for earthquakes within a 500 km radius. This script uses data from British Geological Survey website and returns earthquake activity over the last 30 days.
BGS data is used with permission as long as the attribution built into the script displays with the script output.

Deprecated Scripts

With the release of quake-json.php script on 8-Sep-2012, the following scripts are no longer maintained as the USGS is deprecating the pages on their website that these scripts require:

  • quake-CANV.php
  • quake-USA.php
  • quake-WORLD.php and quake-WORLD-ML.php

The quake-json.php script uses the USGS new GeoJSON feed for 1+ (USA) and 4+ (World) magnitude events and replaces the functionality of the above scripts.
