New Jersey Earthquake Fault Still Undiscovered as Aftershocks Continue

Researchers deploy additional seismometers to monitor ongoing aftershocks and attempt to locate the elusive fault responsible for the rare Northeastern quake.

• Scientists have not yet identified the fault responsible for the April 5 earthquake in New Jersey, which was felt from Maryland to Maine.
• Over 50 aftershocks have been recorded since the initial 4.8-magnitude quake, prompting the deployment of new monitoring equipment.
• The U.S. Geological Survey has installed five new seismometers near the quake's epicenter and plans to add more to improve data accuracy.
• Researchers are using advanced technologies like lidar to investigate the complex fault system, but the exact fault location remains unclear.
• Aftershocks, ranging up to magnitude 3.8, are expected to continue, affecting millions in the densely populated region.
