Examines the processes that shape landforms, the values placed on landscapes, hazards associated with landscapes and their management. Case studies: Australia and other countries.
Australia is known worldwide for some truly distinctive rock formations. But there are few more remarkable than the eerie and astounding Pinnacles Desert.

High up in the French Alps, the climbers who spend their days on the rocks and glaciers have come to a grim conclusion: the mountains are crumbling around them
Geography Teachers' Association of Victoria Inc. (GTAV)'s insight:
climate change is affecting the landforms of the alpine regions as they are more exposed.
Because it happened within the Australian Plate rather than at a plate boundary, shockwaves from the quake travelled more efficiently to Darwin than to cities closer to the epicentre.
Geography Teachers' Association of Victoria Inc. (GTAV)'s insight:
Earthquakes are few and far between in Australia, but a recent quake affected Darwin considerably.
At least 281 people are known to have been killed after a giant wave destroyed hundreds of homes, hotels and businesses along tourist beaches in Java and Sumatra on Saturday.

Anak Krakatoa has been active for more than 100 years and still packs a punch.
Seismic and deformation data indicate magma is trying to rise to the surface at Cerro Azul volcano in Galapagos, Ecuador. An eruption can be expected in the next few days or weeks, probably of the same type as those previously occurring at th

The full power of the biggest temblors could be determined in as little as 10 to 15 seconds after they begin, a new study finds, and long before it ends.
Geography Teachers' Association of Victoria Inc. (GTAV)'s insight:
Predicting earthquakes is, at present, impossiblke. This signal could give some warning.
Four years ago, this island arose out of almost nothing: a sprawling formation of jutting rock popping up in the South Pacific, where once there were only waves.

How does a volcano become a fully vegetated island...this shows the development.
"This is really a new thing to permafrost science. It has not been reported in the literature before,” an Arctic expert said.

Russian scientists recently discovered 7,000 earthen knobs erupting from the Siberian Arctic, each the size of a small hill. It was as though the permafrost had broken out into giant grass-covered mounds. What’s more, an unknown number of these bubbles could contain methane and explode, forming craters, the Siberian Times reported. Using a combination of satellite images and field study, the researchers tallied the bumps. They found far more than previously counted. “At first such a bump is a bubble, or ‘bulgunyakh’ in the local Yakut language. With time the bubble explodes, releasing gas,” Alexey Titovsky, director of the Yamal department for science and innovation, told the Siberian Times. “This is how gigantic funnels form.”
Tsunamis are giant, powerful waves most often caused by earthquakes beneath the ocean floor. Their incredible power can destroy entire communities, the
Earthquakes can cause immense damage to buildings and infrastructure, trigger tsunamis, and reshape the Earth's surface with their force. But how do earthquakes begin, and why are some much more devastating than others?
