Monday Volcano Roundup

You may have noticed that we have a new look for our blog, twitter and Facebook. It was designed to tie in with the celebrations for the 50th anniversary of UEA. If you turn it upside down, what do you see? It looks suspiciously like a big top tent to us…

In real volcano news, there was some activity at Mount Merapi, the volcano we’ve chosen to build a replica of. It started spewing ash up to 1 km into the air,  leading to some villagers around the volcano evacuating their homes.  According to a local geologist and lecturer, this wasn’t an eruption, just the movement of volcanic material from the peak of the volcano – a common process where the volcano’s lava dome partially collapses, releasing ash and other materials. Nonetheless, this just highlights how active Mount Merapi is, and also how the lives of many people living in that region are affected by it.

We’ve made some more progress with our volcano build. We’ve got some GIS data for the volcano, and from this, we’re extracting the height contours every 200 m. Using this data, we’ll make templates for the workshop to cut out of wood, and we’ve these pieces we’ll build a volcano frame. Then we’ll cover the frame with other materials to make it look just like Mount Merapi.

One of the things we still have to work out is how much vertical exaggeration we want for our volcano.  Landscape features look very flat when built to scale, so it is common for the height to be exaggerated by factors of around 2 to 2.5. But we don’t want too much exaggeration, then the volcano would look silly – we just need to figure out exactly how big we can (and want) to make this volcano!
