The article discusses the asteroid 16 Psyche, which is made almost entirely of the metals iron and nickel and is similar to planet Earth's metal core, according to geologist Linda Elkins-Tanton at the Carnegie Institution in Washington D.C.

The article discusses how tides could help predict major earthquakes, such as the March 2011 magnitude 9 earthquake in Japan, which triggered a tsunami. An overview of a report in "Geophysical Research Letters" magazine regarding research by Sachiko Tanaka and colleagues of the National Research Institute for Earth Science and Disaster Prevention in Tsukuba, Japan, investigating the link between minor earthquakes triggered by tidal forces and major earthquakes is presented.

The article discusses the environmental impact of Chile's magnitude 8.8 earthquake, which shook the region so violently that it may have caused a series of volcanic eruptions. Topics include an overview of research by geologists at the University of Oxford who found that volcanic activity increased following a high magnitude earthquake.

The article discusses research on the seeding of Earth with cyanide from comet and asteroid collisions. It references a study by Seiji Sugita of the University of Tokyo in Japan, and Peter Schultz of Brown University in Providence, Rhode Island, published in a 2009 issue of the journal "Geophysical Research Letters." To prove the hypothesis that life on Earth was triggered by cyanide seeding, the researchers fired projectiles made of organic material at metal targets at up to six kilometers per second.
