Seismic Spike at 2,700 Kilometres: Scientists Finally Explain the Deep Earth Signal
Roughly 2,700 kilometres beneath the surface, seismic waves are speeding up in a way that standard geology cannot explain. These waves, triggered by powerful earthquakes, pass through the mantle at expected speeds until they reach a narrow layer just above the outer core. At that point, they suddenly accelerate. The increase is sharp and measurable, […] The post Seismic Spike at 2,700 Kilometres: Scientists Finally Explain the Deep Earth Signal …
