Earthquake Monitor v2.0.1 released

Dear readers,

2 weeks ago I have released v2.0.0 of the earthquake monitor. A lot has changed in this release.

Today v2.0.1 is released with some little bug fixes!

  • Added a new variable {tsunami}. When enabled in menu and added to the template it shows a tsunami icon when a major event in an oceanic region has occured.
  • Added a new variable {type} that will display the type of event (earthquake ,quarry, chemical explosion e.t.c.)
  • Added shortcode [eqmonitor] to add (multiple) earthquake lists in pages or posts (more details in the Shortcode examples and parameters section of this readme)
  • Switched to Semantic Versioning MAJOR.MINOR.PATCH
  • All links that take care of JSON data-exchange are now HTTPS (SSL)
  • All links to PHP documentation are now HTTPS
  • Adjusted the yellow pager color to be a bit more darker (and readable on white backgrounds) (This can be altered in the CSS)
  • You can now use this widget multiple times on the same site. Each widget has an unique identifier and uses it’s own unique cache.

You can try it out here :

Oh, and here is a live example of the shortcode that has been added.

<eqmonitor id=’unique1′ cachetimer=’3600′ numberedlist=’true’ showmax=’10’ showlink=’false’ minmagnitude=’7′ showdaysback=’364′>

(Where < = [ and > = ] , can’t paste that or the shortcode is executed :))

  2. M 7.1 - 2019 Ridgecrest Earthquake Sequence 4 months ago Tsunami Icon

Subnetinfo new WordPress Addon

I have been working on a new little plugin to make life a bit easier.
This addon uses a shortcode to parse IPv4 and IPv6 addresses in nice detailed boxes.

Will become

Address IPv6: 2001:485:7a2:1200:a285:c66f:fb56:1d77 / 64 Netmask: ffff:ffff:ffff:ffff:0000:0000:0000:0000 Wildcard: 0000:0000:0000:0000:ffff:ffff:ffff:ffff HostMin: 2001:0485:07a2:1200:0000:0000:0000:0001 HostMax: 2001:0485:07a2:1200:ffff:ffff:ffff:fffe IP Addr. full: 2001:0485:07a2:1200:a285:c66f:fb56:1d77 Heximal ID: 0x2001048507a21200a285c66ffb561d77 Type address: Global Unicast RFC2928
Address IPv4: / 24 Netmask: Decimal IP 3232261130 Heximal IP 0xC0A8640A Binary IP 11000000101010000110010000001010 Binary Subnet 11111111111111111111111100000000 Wildcard: Network: Broadcast: HostMin: HostMax: Usable hosts: 253 Network Class: C (Private Network RFC1918 )

This is all it does for now. Suggestions are welcome ofcourse.

Antenna mod for my WMR-200 weather station.

I was having a lot of problems with the default mounted antenna of my Oregon Scientific WMR-200
Weatherstation. This resulted in not receiving the temperature sensor. The distance between my temperature sensor and the receiver is aprox. 20 meters (line of sight) but this was enough to allow interference stop receiving the signal for a long time (usually all night)

You can see that in some historical records

2015-07-05 00_00_09-Stadspolders Dordrecht, NL Weekly weather summary








2015-07-05 00_01_07-Stadspolders Dordrecht, NL Current Weather Conditions


This resulted in a lot of N/A readings.

Today I have removed the original antenna from my WMR-200 and I have mounted a new antenna with a better gain. Since the signal is tranmitted over 433.92 Mhz I ordered an antenna that is suitable for this job.





So, i will tell you what materials I used for this little modification.

1 x High gain antenna (suitable for 433.92 Mhz) (Diamond RH9541S)

1 x SMA Male to SMA Female RG316 Cable

1 x Solderering Iron

1 x Little piece of wire

A little bit of Teflon tape (or other tape)

Earthquakemonitor Widget v1.7 released

2015-06-30 22_03_40-WordPress › Earthquakemonitor Widget « WordPress Plugins

Hooray again 🙂

Earhquake monitor v1.7 is released. This release has a total new cache structure and also a new feature is added.


PAGER (Prompt Assessment of Global Earthquakes for Response) background

PAGER (Prompt Assessment of Global Earthquakes for Response) is an automated system that produces content concerning the impact of significant earthquakes around the world, informing emergency responders, government and aid agencies, and the media of the scope of the potential disaster. PAGER results are generally available within 30 minutes of a significant earthquake, shortly after the determination of its location and magnitude. However, information on the extent of shaking will be uncertain in the minutes and hours following an earthquake and typically improves as additional sensor data and reported intensities are acquired and incorporated into models of the earthquake’s source.

Corresponding fatality thresholds for yellow, orange, and red alert levels are 1, 100, and 1,000, respectively. For damage impact, yellow, orange, and red thresholds are triggered by estimated losses reaching $1 million, $100 million, and $1 billion respectively.

2015-06-30 21_59_59-PAGER - Background






Further this is the changelog :


  • Need PHP v5.3 or higher
  • If the earthquake is located in the middle of no-where (not in or near a city or area) it will display the Flinn-Engdahl Region name. This prevents empty rows with only a magnitude showing.
  • Added optional display of PAGER (Prompt Assessment of Global Earthquakes for Response) color codes. ( See )
  • Bug fix when names with ‘ appeared in TITLE link.
  • Prefixed function-names to be more Unique.
  • JSON Feed error is only visible in source code (so it won’t destroy layout)
  • Cache function improved (now using database instead of /tmp directory)
  • Automatic refresh cache when feed properties are changed.
  • New screenshots frontend and backend.
  • Uninstall script present.
  • Various readme.txt adjustments.
