We often have a way of seeing patterns in otherwise random features, and rock outcrops are no exception. Do you see the heart on its side? To the untrained eye an outcrop like this is simply a heart-shaped feature in an otherwise grey rock. But to the geologist, the layers, swirls, shapes and colours tell a story. The ribbons in the granite show that the rock has been subjected to sheer forces and ...[Read More]

The unexpected seismic hazard
Public places such as airports are often designed to withstand strong earthquakes particularly in modern cities that are prone to earthquakes. When the ground shakes people have to be careful from objects falling off walls … or eagles falling from the roof! Two large eagles each having a wingspan of 15 meters and weighing 2 tonnes were suspended from the roof of Wellington Airport to promote ...[Read More]

Geosciences Column: Using tall trees to tot up tropical carbon
Forests in the tropics account for about half the above-ground carbon on Earth and as the trees grow older they are capable of storing more and more. In fact, their carbon-storing potential is so large that they are increasingly being viewed as a means of mitigating climate change. Take, for example, the United Nations effort to reduce degradation and deforestation by assigning value to forest car ...[Read More]
