Sentences with phrase «active subduction»

This finding has applications to the seismic hazard of these regions, as it highlights the potential for future damaging earthquakes and tsunamis at active subduction margins with no measurable recent uplift.

We hope that this new finding will promote the mapping and discovery of such faults along active subduction margins and will also help explain the variability in the recurrence of great - earthquakes encountered on many subductions globally.»

Asked what's new with these findings Vasiliki Mouslopoulou explains: «For the first time temporal clustering of great - earthquakes is shown on active subduction margins, indicating an intense period of strain release due to successive earthquakes, followed by long periods of seismic quiescence.»

Vasiliki Mouslopoulou says: «It is not unlikely that coastlines along active subduction margins with no detectable tectonic uplift over the last 10,000 years will accommodate bigger than M7 earthquakes in the near future.»

The island nation sits atop an active subduction zone where the Pacific Plate slips below the Australian Plate.

In the early 1980s, two Caltech geophysicists, Tom Heaton and Hiroo Kanamori, compared Cascadia to active quake - prone subduction zones along the coasts of Chile and Alaska and to the Nankai Trough off the coast of Japan.

«Orogenic oceanic - continental subduction zones have been common as long as modern plate tectonics have been active,» Delph said.

Although the South America plate exhibits a chain of active volcanism resulting from the subduction and partial melting of the Nazca oceanic lithosphere along most of the arc, these regions of inferred shallow subduction correlate with an absence of volcanic activity.

The convergence associated with this subduction process is responsible for the uplift of the Andes Mountains, and for the active volcanic chain present along much of this deformation front.

However, it has been controversial whether these structures are old or whether the so - called subduction process is still active,» explains Heidrun Kopp.

Onno Oncken of GFZ comments: «This is an intriguing finding that changes the stereotype view that all or most great subduction earthquakes occur along the active contact, i.e. plate - interface, of the two converging plates.

«What this work shows is that, contrary to some previous estimates, the two middle sections of the Cascadia Subduction Zone that affect most of Oregon have a frequency that's more similar than different,» said Goldfinger, who directs the Active Tectonics and Seafloor Mapping Laboratory at OSU.
