Geodesy, the oldest science, has become an important discipline in the geosciences, in
large part by enhancing Global Positioning System (GPS) capabilities over the last 35 years …

As subducting plates reach the base of the upper mantle, some appear to flatten and
stagnate, while others seemingly go through unimpeded. This variable resistance to slab …

Subduction zones are home to the most seismically active faults on the planet. The shallow
megathrust interfaces of subduction zones host Earth's largest earthquakes and are likely …

We present a narrative of the eruptive events culminating in the cataclysmic January 15,
2022 eruption of Hunga Tonga-Hunga Ha'apai Volcano by synthesizing diverse preliminary …

Since its inception in the 1960s, probabilistic seismic-hazard analysis (PSHA)(Cornell, 1968;
McGuire, 2004, 2008) has emerged as the principal methodology for assessing the potential …

Abstract We reconstructed Philippine Sea and East Asian plate tectonics since 52 Ma from
28 slabs mapped in 3‐D from global tomography, with a subducted area of~ 25% of present …

We study the age of the subducting Pacific slab beneath East Asia using a high-resolution
model of P-wave tomography and paleo-age data of ancient seafloor. Our results show that …

The subduction zone in northern Chile is a well-identified seismic gap that last ruptured in
1877. The moment magnitude (M w) 8.1 Iquique earthquake of 1 April 2014 broke a highly …

Indonesia is one of the most seismically active countries in the world, and its large,
vulnerable population makes reliable seismic hazard assessment an urgent priority. In 2016 …

The water cycle at subduction zones remains poorly understood, although subduction is the
only mechanism for water transport deep into Earth. Previous estimates of water flux,–exhibit …
