‘Supershear’ Quakes More Common Than Believed |
Some of California’s biggest faults can produce a rare and dangerous kind of quake — and most people have never heard of it. In a recent opinion piece, USC Dornsife Earth scientists warn that “supershear” earthquakes could hit the state hard and fast.
Why it matters: Supershear quakes move faster and pack more power than typical earthquakes.
|
- Their speed makes them harder to detect in time to react.
- They create stronger ground shaking — especially along major fault lines near cities.
|
- High-risk faults include parts of the San Andreas, San Jacinto and Elsinore faults — all near heavily populated areas.
|
The big picture: Supershear quakes are rare — but concern is rising as scientists learn more.
|
-
The 2018 quake in Palu, Indonesia, is among the most destructive recent examples.
- Past California quakes, including 1979’s Imperial Valley quake, showed supershear characteristics.
|
How it works: Supershear quakes happen when the rupture races faster than seismic shear waves, creating a shockwave-like effect similar to a sonic boom.
|
- The result is longer and more intense shaking in the direction of the rupture.
|
Earthquake early warning systems may struggle to keep up with supershear events, and more fault zones may be reclassified as “supershear-capable” as research expands.
The bottom line: The authors warn that California needs to up its game with better monitoring near major faults, advanced computer simulations of supershear scenarios, and stronger building codes.
In his words: “Critical structures should be built to [a] higher standard, and so far, they are not,” Ben-Zion said.

Ocean Allies Tag-Team Methane Cleanup |
Deep in the ocean, microbes are working together to consume methane, a powerful greenhouse gas. New USC Dornsife research reveals how these tiny partners make the planet a bit safer.
Why it matters: Methane traps heat at least 80 times more effectively than carbon dioxide over 20 years.
|
-
Oceans hold huge stores of methane under the seafloor.
- Microbes help keep that methane from reaching the atmosphere.
|
What’s new: Dean’s Professor of Physics and Astronomy Moh El-Naggar and collaborators discovered surprising teamwork between two types of microbes.
|
-
Organisms called archaea start the job by breaking down methane.
- Bacteria finish it by processing leftover compounds.
- The collaboration happens in oxygen-free zones under the ocean floor.
|
How they did it: Researchers used advanced gene sequencing on deep-sea sediment samples from the Santa Barbara Basin off California.
|
-
They studied gene activity to see how the microbes shared the work.
|
What it means: The microbes’ relationship is more flexible and efficient than expected.
|
-
It’s a form of syntrophy — sharing resources to survive.
- They can adapt to different environments and methane levels.
|
Between the lines: This discovery could improve climate models and methane control strategies.

Tiny Foxes Defy Evolutionary Rule |
Tiny foxes on California’s Channel Islands evolved larger brains than their mainland cousins, challenging a long-held scientific theory.
Why it matters: This finding, from a study led by biology PhD candidate Kimberly Schoenberger, forces scientists to rethink how animals adapt to isolated environments — crucial knowledge as climate change creates more fragmented habitats worldwide.
The big picture: Scientists have long believed that island-bound animals evolve relatively smaller brains to conserve energy.
What’s new: USC Dornsife researchers found that five of six Channel Island fox sub-species have bigger brain-to-body ratios than their mainland gray fox cousins, who share a common ancestor.
The discovery suggests that the demands of survival, not isolation itself, drive brain size changes on islands.
|
-
A relatively larger brain helps Channel Island foxes with the motor control and spatial skills needed to forage, navigate harsh terrain and coexist with rivals like the spotted skunk
|
In her words: “The Channel Island foxes show that brain size reduction is not a universal feature of island life. It depends on the pressures each species faces,” said Kimberly Schoenberger, the study’s lead author.
