Earthquake Notifier for Google Chrome

Note - May 26. 2011: This information is kind of outdated. It will be updated within the next couple of weeks or months. But it is still informative.

This extension is for those who have relatives or friends in parts of the world that got hit by an earthquake, for
those who want to know how hard aftershocks are hitting nearby regions and for those who are directly affected by them.

It's for those who want to look at raw scientific data in a way which matters most, easily understandable
with all the noise filtered out, in an extension built with love and great care to detail.

It transforms this

into this

and let's you know when something new occurred


After clicking on the install link, the extension will be downloaded.
Once this is done, you will need to click on the continue button to add the extension to the browser.

Then you need to give the permission for the extension to access the data on the domain, which will be providing the earthquake data.

Once the extension is installed, you can click the earthquake badge which has just been added to the browser.

Clicking on the badge will open the popup window which will show you all the current earthquakes.


Next you will need to configure the extension by adding the cities and countries you care about.

To get to the options page, 1) right click the new badge and 2) click on Options

Please watch this introduction video to see how to configure the cities and countries you care about.

In the Updates section of you can decide how often new earthquake data should be downloaded.

Selecting "As often as possible" will let the server which is providing the data tell the extension
how often it should look for new data, always attempting to make the update interval as small
as possible.

The "blue mark" on the icon is a small text labeled "chk" which let's you know when data is being
downloaded from, and how long it is taking. Some may find it distracting
so it's possible to turn it off.

In the Distances section you can select your unit of preference (default is km).

Usually earthquakes which are further away than 400km are not really that dangerous, so they
can be dimmed out so that the closer, more dangerous ones are more visible. You can change this
value so that it suits your preferences.

If an earthquake which is more than 400km away should be considered as dangerous, then it must
be a strong one and will very likely show up as a completely red marked earthquake, as configured
in the next secion.

Earthquakes which happen really far away from a city are dimmed out even more, since that data
is always irrelevant.

These options here are quite self explanatory.

If you increase the number of days into the past, the older data may need to get downloaded first.
To do this, you need to click on the Download the missing x day(s) button and wait.


You can leave the popup open, it will refresh itself automatically when new earthquakes are detected.
