研究揭示尼泊尔西部喜马拉雅港湾状地形的形成
研究人员通过热运动学研究发现,沿着板块汇聚界面大型逆冲断层在中下部地壳深处的地壳物质堆叠塑造了高原的生长和区域水系的发育。
Billion-Year Rewind Tracks Supercontinents and Mantle Structures
Scientists have traced past pathways of tectonic plates back a billion years using computer models, with intriguing results. Incorporating geologic data as a check on model output, however, has proven tricky.
¿Tienen los terremotos y las placas tectónicas una relación bidireccional?
Un terremoto catastrófico en Turquía que sucedió en 1999 cambió el movimiento de la placa de Anatolia, según un estudio que podría modificar los fundamentos de modelamiento de los terremotos.
Seismic Sources in the Aleutian Cradle of Tsunamis
Research over the past decade in Alaska’s Aleutian Islands has offered surprising insights into the pulses of great earthquakes that generate dangerous, often long-distance tsunamis.
Global Seismic Networks: Recording the Heartbeat of the Earth
Global broadband seismographic networks have provided the science community with 30 years of data which is being used to understand the Earth.
Old Igneous Rocks Hold the Key to Crustal Thickness Evolution
The chemical composition of orogenic igneous rocks and their zircons is sensitive to crustal thickness and can be used to quantify the evolution of Moho depths beneath continents back in time.
Probing the Sedimentology of a Continental Megathrust
Detailed analysis of sediments covering the Main Frontal Thrust in Nepal show how climate-driven baselevel changes affect sedimentation and should be considered when inferring thrust activity.
Months of Gravity Changes Preceded the Tōhoku Earthquake
Using GRACE satellite data, researchers discovered anomalous gravimetric signals that occurred before a seismic event that started deep within Earth.
Uncovering the Formation of the Western Nepal Embayment
Using thermokinematics, researchers have found that crustal accretion along the megathrust at mid-lower crustal depths shapes plateau growth and regional drainage development.
