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.

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

15 earthquakes found. Click on location or map links for more details from the USGS

This was invoked by using the following code:

<?php 
  $doIncludeQuake = true;
# uncomment ONE of the $setDistanceDisplay lines to use as template for distance displays  
#  $setDistanceDisplay = 'mi (km)';
  $setDistanceDisplay = 'mi';
#  $setDistanceDisplay = 'km (mi)';
#  $setDistanceDisplay = 'km';

  $setDistanceRadius  = 200;  // same units as first unit in $setDistanceDisplay
# NOTE: quakes of magnitude 1.0+ are available for USA locations only.
#    non-USA location earthquakes of magnitude 4.0+ are the only ones available from the USGS
  $setMinMagnitude = '2.0';  // minimum Richter Magnitude to display
  $setHighMagnitude = '4.0';  // highlight this Magnitude and greater
  
  $setMapZoomDefault = 7;    // default zoom for Google Map 1=world to 13=street
# script will use your $SITE[] values for latitude, longitude, timezone and time display format
  include_once("quake-json.php");
  ?>

Also required is the styling and JavaScript <script> statements in the <head>...</head> part of the page (see the sample quakes.php page in the distribution quake-json.zip package for details).

The USGS GeoJSON earthquake script (V1.08 - 06-Jul-2015):
demo | download .zip package | download script only [ 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-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.
