Deciphering the Fate of Plunging Tectonic Plates in Borneo
What happens when subduction stops? A team of scientists installed a dense seismic network in Borneo to investigate causes and consequences of subduction termination.
Linking Observations and Modeling of Flat-Slab Subduction
The Center for Tectonics and Tomography: Workshop on Flat Slab Subduction; Houston, Texas, 18–20 January 2019
Unraveling the Origin of Slow Earthquakes
Different nucleation styles detected in five slow-slip events in the same area of Japan’s Ryukyu subduction zone suggest the physical properties along this tectonic plate interface change over time.
Can Earthquakes Trigger Volcanic Eruptions?
A new study supports the idea that earthquakes may be associated with increased volcanic eruptions, but over longer time spans than prior research indicated.
Investigating the Northern Indian Ocean’s Puzzling Geodynamics
International Ocean Discovery Program (IODP) Proposal Nurturing Workshop on Indian Ocean; Goa, India, 17–18 September 2018
In a Submarine Trough, Permeable Rocks May Lead to Quakes
In Japan’s submarine Nankai Trough, rock permeability is much higher when measured at larger scales, likely because of big fractures and faults that are not captured at small scales.
Unraveling the Origins of Australia’s Ancient Mountain Chains
New data synthesis suggests that varying rates of trench retreat along the margin of the Gondwana supercontinent were responsible for the curvature of the Tasmanide mountain chains.
At-Sea Workshop Advances Subduction Zone Research
International Ocean Discovery Program Core-Log-Seismic integration at Sea (CLSI@Sea) workshop; Nankai Trough, Philippine Sea, off the coast of southwest Japan, January–February 2018
Constraining Central Washington’s Potential Seismic Hazard
Fault geometry and slip rate analyses show deformation in the Yakima Fold Province accelerated in the Pleistocene and has remained elevated, offering new insights into earthquake recurrence intervals.
