Delineating Deep Faults Most large, damaging earthquakes initiate in Earth's crust where friction and brittle fracture control the release of energy. Strong can occur mantle too, but their rupture dynamics are difficult to determine because higher temperatures pressures play a more important role. Ye et al. (p. 1380 ) analyzed seismic P waves generated by 2013 M w 8.3 Sea Okhotsk earthquake—the largest deep earthquake recorded date—and its associated aftershocks. The ruptured along fault...
Abstract The 1938 M S 8.3 and 2021 W 8.2 earthquakes both ruptured within the Semidi segment of Aleutian‐Alaska subduction zone. large‐slip distribution event is well constrained depth range 25–45 km, with seaward tsunami observations excluding significant shallower coseismic slip. slip more uncertain. Regional far‐field tide gauge for are modeled to constrain location large largest (2.0 m) located below continental shelf on a 180‐km‐long portion rupture extending further northeast than...
Abstract A great earthquake struck the Semidi segment of plate boundary along Alaska Peninsula on 29 July 2021, re‐rupturing part 1938 rupture zone. The 2021 M W 8.2 Chignik occurred just northeast 22 2020 7.8 Simeonof earthquake, with little slip overlap. Analysis teleseismic P and SH waves, regional Global Navigation Satellite System (GNSS) displacements, near‐field far‐field tsunami observations provides a good resolution process. During ∼60‐s long faulting, was nonuniformly distributed...
Abstract The Altyn Tagh fault (ATF) system forms the northern margin of Tibetan Plateau and plays a crucial role in uplift development Plateau. It mediates far-field effect collision between Indian Eurasian plates. Because limited constraints on lithospheric velocity structure, detailed deformation pattern central ATF remains unclear. With dense seismic array, 483 stations with an interval ∼1 km, across (the Tarim–Altyn–Qaidam nodal array) late 2021, we obtain 14,079 high-quality teleseismic...
Granular flows, such as landslides and rock avalanches, are a prevalent geological hazard in mountainous regions, necessitating accurate dynamic modeling for disaster prevention. We investigate the influence of particle composition flow regimes on granular dynamics seismic response through series flume experiments. By varying size distributions inclinations, we analyzed kinematic properties, signals, interplay between characteristics. The results demonstrate that significantly impacts...
The episodic stick-slip behavior of megathrust faults in subduction zones can lead to severe earthquakes and tsunamis that pose a catastrophic threat coastal populations. It is therefore great importance study their seismogenic conditions earthquake activity. Sumatra Java, located seaward the Sunda Arc, are geographically neighboring, but phenomena differ significantly. zone has been scene numerous very strong (Mw > 8), including 2004 magnitude Mw 9.1, while Java experienced only limited...
Abstract Most great earthquakes on subduction zone plate boundaries have large coseismic slip concentrated along the contact between subducting slab and upper crust. On 4 March 2021, a magnitude 7.4 foreshock struck 1 hr 47 min before 8.1 earthquake northern Kermadec island arc. The mainshock is largest well‐documented underthrusting event ∼2,500‐km long Tonga‐Kermadec zone. Using teleseismic, geodetic, tsunami data, we find that all substantial in located mantle/slab interface at depths...
Abstract Rapid determination of sea level variations caused by tsunamis or major storm surges is important for coastal hazard mitigation. Coastal Global Navigation Satellite Systems (GNSS) stations at elevations less than ∼300 m can record time‐varying changes tracking signals that reflect from the surface, relative to direct satellites. We demonstrate such GNSS rapidly provide local measurements a near‐field tsunami, involving many hours shelf resonance generated 2020 Shumagin earthquake as...
Despite a moderate magnitude, M w = 6.4, the 5 February 2016 Meinong, Taiwan, earthquake caused significant damage in Tainan City and surrounding areas.Several seismograms display an impulsive S-wave velocity pulse with amplitude of about 1 m s -1 , which is similar to large pulses recorded for past several larger damaging earthquakes, such as 1995 Kobe, Japan, (M 6.9) 1994 Northridge, California, 6.7).The observed PGV area 10 times than median 6.4 crustal earthquakes Taiwan.We investigate...
Abstract On 18 November 2022, a large earthquake struck offshore southern Sumatra, generating tsunami with 25 cm peak amplitude recorded at tide gauge station SBLT. Our W ‐phase solution indicates shallow dip of 6.2°, compatible long‐period surface wave radiation patterns. Inversion teleseismic body waves slip distribution extending from about 10 km deep to near the trench maximum ∼4.1 m and seismic moment Nm ( M 7.3). Joint modeling data rigidity ∼23 GPa. We find low moment‐scaled radiated...
