In the same way that the number of rings in a tree can tell us its age, the characteristics of rocks such as breccia can tell us about the history of a region. The breccia around Ichinokawa Mine (located in Ehime prefecture) are of particular interest, as the mine is located south of the Median Tectonic Line. Researchers at Tohoku University uncovered how breccia can provide valuable evidence to estimate the energy of past earthquakes in the area.

Miyako Islands are home to various native species of snake and lizards. How these species came to call these islands home has long puzzled scientists. A group of researchers from Tohoku University have compiled the latest geological and biological data, proposing that an island once facilitated migration between Okinawa and Miyako Islands.

An international research team has discovered that a subduction zone’s age affects the ability for it to recycle water between the Earth’s surface and its inner layers. The more mature the subduction zone, the bigger the water storage capacity.

We don’t know much about the Earth’s inner core because recreating its conditions in a laboratory setting remains fraught with difficulties. Based on tracking seismic waves, scientists theorize that the area in and around the core comprises mostly of iron. But the values extracted from these indicators differ from how pure iron typically behaves. Now, a collaborative research group has succeeded, for the first time, in measuring the speed of sound of pure iron under pressures similar to the Earth’s inner core boundary.

The Gunflint Formation, which straddles Lake Superior’s northwestern shore, contains a treasure trove of geological clues about the evolution of life. After a recent geological reassessment of this area, a research team has unearthed new types of microfossils dating 1.9 billion years. The landmark discovery will help scientists pinpoint the timing and factors that ushered in the evolution of prokaryotes to eukaryotes.

Dinosaurs came to flourish during the Jurassic period after a volcanic eruption roughly 201 millions years ago wiped out many marine and land animals, leaving them able to evolve and grow. Now, further details about this eruption and the mass extinction have been revealed. A group of researchers demonstrated how low temperature magma slowly heated sedimentary rocks, causing high sulfur dioxide and low carbon dioxide emissions, a process which cooled the earth.
