There’s just been a large earthquake near Tonga in the South Pacific. (BBC article) Nobody was hurt thankfully, so it seemed like a good time to compare how Earth Browser and Google Earth report the event.

I’ve noticed that the Google Earth USGS network link for recent earthquakes has been improved with a floating legend. It’s one of the most useful Google Earth add-ons.The image below illustrates how the network link has displayed the earthquake in Tonga.

Earth Browser is still my favourite application for near real time analysis of tectonic hazards in school, being slightly faster and more reliable on my rather over-stretched school laptop. The globe has been enhanced recently and is even more beautiful. The image below shows the earthquake in Earth browser.

In both appplications, clicking on the earthquake icon takes you to the relevant USGS page. I marginally prefer the way that Earth Browser displays the magnitude of the event on the icon, and it is faster to display earthquakes once the database has refreshed.

I thought I’d post a Google Earth placemark created by Year 8 students as part of my lesson for visualizing a safer San Francisco. The placemark locates a suitable site for a new hospital. See previous post

Lots of placemarks were created by the class, and a peer assessment exercise selected this one as the best overall site. I was impressed by the detail, and the way the students selected information from the standard Google Earth layers as well as the overlay information provided. The students also make links to previous learning.

A class of (very) mixed ability year 8 students have begun work on my San Francisco decision-making exercise.

After the first session they have come up with some suggested sites for a new hospital, designed to be safe from earthquakes. Download the file here

The original lesson resource is here

Next lesson we will have a little peer assessment and the opportunity to improve and refine their decisions.

Any feedback is most welcome and will be passed to the students.
