Improving tsunami hazard assessments depends on understanding what happens at the moment an earthquake ruptures beneath the seafloor, especially near deep-ocean trenches where measurements are often scarce.

As warmer temperatures melt polar ice, a parallel danger lurks in high mountain areas where melting glaciers have created thousands of new lakes.

A massive fault beneath Sulawesi, Indonesia, has been confirmed to extend offshore as a continuous deep fracture through Earth’s crust.
