Solar-driven temperature shifts alter rock properties and underground water movement, potentially making the Earth’s crust ...

This suggests that tectonic forces—not just mountain weight—are pulling the land downward. The shifting plate could lead to increased seismic activity. As stress redistributes within the crust ...

The quake was initially recorded at 7 magnitude which struck at a depth of 10 kilometres (6.2 miles) off the southwest tip of the South Island, the USGS said.

Pressure from a pool of magma has just cracked solid rock, creating a volcano-tectonic (VT) event. This type of quake produces relatively high-frequency shaking, usually between one and five ...

Plate tectonics is the theory that Earth's outer layer is made up of plates, which have moved throughout Earth's history. The theory explains the how and why behind mountains, volcanoes ...
