JJNN: Remap

Welcome again to JJNN for March 3rd, 2009. Today I will be talking about the remapping of Japan.

There are a lot of little dangers when you live in the land of active volcanoes and earthquakes. I mean, your house could be swept away by a river of magma, or something could fall on you and kill you during an earthquake. Those are both terrible, but they don't even come close to the terror of not being able to find your way around with your car's navigation system. Sure, it is not as obvious as buildings falling down and burning to the ground, but that is also one of the side effects that you have to deal with when you live in land of active plate tectonics.

According to this news story, there have been changes in the landscape of Japan because of earthquakes and plate tectonics. A good example of this is Mt. Odaigahara in Southern Japan. The height of the mountain actually increased 12 centimeters (almost 5 inches) since last they measured how high it was. At another place in southern Japan the Geographical Survey Institute has to remeasure over 3000 triangulation points because they have moved. They are using GPSs to help make the measurements.

I will leave you with a picture of the new taller Mt. Odaigahara.
