Megathrust earthquakes occur when stress at subduction zones is released, causing significant plate slippage. These events disrupt long-term tectonic changes, complicating modeling efforts.

More specifically, subduction zones — where tectonic plates slip over and under each other — can push land to open or close oceans. Researchers found that an inactive subduction zone under the ...

Amid Earth’s mobile tectonic plates, subduction zones arise as regions of intense geological activity and concentrate minerals into ore deposits like gold.

A 4.2 magnitude earthquake struck about 143 miles southwest of Tofino, B.C., at around 5:53 a.m. A second 3.0 magnitude ...

Aside from the danger they pose, such earthquakes disrupt the slow, long-term changes occurring at subduction zones. The cycle of sudden earthquakes and slow plate movement makes it difficult for ...

The magnitude 7.9 Bonin Islands earthquake sequence in May 2015, which ruptured deep within the earth near the base of the ...

The modern understanding of the plate tectonic cycle predicts that remnants of submerged plates will be found near subduction zones. However, a new high-resolution model shows that these remnants ...

PORTLAND, Ore. (KOIN) – A new study mapping the Cascadia Subduction Zone is giving scientists clues about the state of the ...

Tozer said the findings could also be compared with data from other subduction zones to better understand what made some faults more likely to generate big tsunamis than others. For instance ...
