New Zealand – Feature site: Seabreeze by Highace
Posted on July 17, 2012
Note: Whilst the owner of the site is an email acquaintance this appraisal is entirely unsolicited and has been made by me because a light is being hidden under a bushel.

One of the most comprehensive sites dealing with New Zealand earthquakes that I have come across is the site that is run by 'Highace'.

The main New Zealand data site is called Seabreeze and is packed with google maps, charts and graphs about seismicity in the area. Because New Zealand is often poorly covered by other data providers around the world it is good to know that, apart from the GeoNet site – the official NZ earthquake data providers, there is a place where you can view historical data and get to see some good analysis.

As an example the about page, where the maps are explained has a detailed set of information to guide you.

What I see from pages like this is time and attention to detail not being spared, the result being an excellent informative site.

In addition to the 'front page' you will also find:

New Zealand wide earthquakes for the last 7 days located by Geonet
New Zealand wide earthquakes for the last 30 days located by Geonet. Sample image.

Years Timeline – Similar to the graph above these graphs show the sequence of a years worth of earthquakes for New Zealand, the x axis(vertical) shows the magnitude, the y axis (horizontal) shows the date, (month/day)
NZ Seismic Cross Sections – This page contains 23 cross sections of New Zealand showing earthquakes located between Jan 1 and Jan 27 2011 by depth, latitude, longitude and magnitude.
SNZO Archives A selection of archived IU-SNZO webicorder plots. Not just boring old plots but mostly fully annotated as to the events being displayed.

I consider the Seabreeze site an outstanding contribution to earthquake blogging.

Please also note that this same blogger maintains a World Earthquakes Magnitude 7+ site and another jewel of a site call Earthquake archives (not USGS) where you will find listings for various providers, and other graphs etc. See image of the menu below.
