EARTH Magazine: Precise to a fault: How GPS revolutionized seismic research

Prior to the quake, geoscientists had placed GPS markers in and around the San Francisco area. Immediately after the quake, researchers converged on the area to collect and compare the pre- and post-quake GPS data, which revealed the direction and speed of surface movements, allowing scientists to infer the pattern of slip on the fault plane that had ruptured far underground.

EARTH Magazine: Ocean Dynamics Speed Sea-Level Rise Along U.S. East Coast

Changing Gulf Stream patterns, shifting climate and increased computing powers are helping answer why sea-level rise on the U.S. East Coast is higher than the global averages, according to a new story in EARTH Magazine.

EARTH Magazine: Giant Quakes Sloshed Fjords Half a World Away

Norwegian citizens living along fjord coastlines were perplexed as rare waves sloshed along local docks and seawalls. Scientists identified and described the rare phenomenon: seismically generated water waves called seiches, which had been set in motion by the massive Tohoku earthquake half a world away.
