A M7.4 earthquake struck off the southern Philippines on October 10. Where the Philippine Sea Plate dives beneath the Sunda Plate, complex subduction on both sides of the Philippines archipelago makes the region highly seismically active.

M7.4 just struck the coast of the #Philippines at a depth of 58.1km according to the USGS.
The #earthquake shown occurred on the western margin of the Philippine Trench, where the Philippine oceanic plate begins its subduction beneath the Mindanao microplate.

The information box highlights the main event.

No single map of sediment thickness across the conterminous U.S. existed that used a consistent method — until this new one based on Transportable Array seismic data.

Magnetotellurics (MT) measure the conductivity (or resistivity) of the Earth. Earth’s magnetic field induces electric currents in the Earth. The strength of this induced signal depends on the conductivity of the materials below the surface.

As the NSF GAGE and SAGE facilities come to a close, we thank the NSF for its sustained investment and our community for advancing geophysical research and education. EarthScope is honored to serve as operator of the new NSF National Geophysical Facility, ushering in the next era of geophysics.

Infographic titled "Celebrating the Impact of NSF’s GAGE and SAGE Facilities (2018–2025)." Lists: 551 experiments, 31,942 unique datasets, 12,643 peer-reviewed publications, 14,001 unique authors, and 448,729 citations. Each statistic is paired with a simple icon. Background shows a shaded relief map with a red-to-purple gradient border at top and bottom.

Each arrow on this map is a GPS velocity vector showing how the ground is moving relative to interior eastern North America. The arrow’s length tells us the speed (longer means faster), and its direction shows where the ground is moving, revealing how tectonic forces are shaping the western US.
