Chrome web store

I have just been looking at what is available in the Chrome Web Store. There are some interesting applications or Web 2 tools that would be good for schools however...

I have been looking at the map showing earthquakes that have happened in the world during the last 7 days.

As you can see from the screen shot it tells us that there have been no earthquakes of a magnitude of 2.5 or above in my country in the last seven days. They say none at all!!!

This is completely incorrect as we have had 27 earthquakes in my city (or surrounding countryside) in the last seven days! Where am I? Christchurch New Zealand. The majority of these earthquakes are over 2.5 but of course that is not a big quake as far as we are concerned. Below you can see a screen dump of where some of these earthquakes happened, their magnitude and the depth.

What concerns me here is that if there is such a glaring error i.e. 27 earthquakes not registering on this site how accurate are any of the other offerings here?

If you are using any with your class I would suggest that you check it out carefully before the children use it.
