Abstract To understand whether the 1992 M = 7.4 Landers earthquake changed proximity to failure on San Andreas fault system, we examine general problem of how one might trigger another. The tendency rocks fail in a brittle manner is thought be function both shear and confining stresses, commonly formulated as Coulomb criterion. Here explore changes conditions associated with or more earthquakes may subsequent events. We first consider criterion appropriate for production aftershocks, where...
We argue that key features of thrust earthquake triggering, inhibition, and clustering can be explained by Coulomb stress changes, which we illustrate a suite representative models detailed examples. Whereas slip on surface‐cutting faults drops the in most adjacent crust, blind increases some nearby zones, particularly above source fault. Blind thrusts thus trigger secondary at shallow depth typically produce broadly distributed aftershocks. Short ruptures are efficient triggering...
The 28 June Landers earthquake brought the San Andreas fault significantly closer to failure near Bernardino, a site that has not sustained large shock since 1812. Stress also increased on Jacinto Bernardino and southeast of Palm Springs. Unless creep or moderate earthquakes relieve these stress changes, next great southern is likely be advanced by one two decades. In contrast, north Los Angeles dropped, potentially delaying there 2 10 years.
In a study of geological and geophysical data from the Mid‐Atlantic Ridge, we have identified 17 large, domed edifices (megamullions) that surfaces corrugated by distinctive mullion structure are developed within inside‐corner tectonic settings at ends spreading segments. The elevated residual gravity anomalies, limited sampling has recovered gabbros serpentinites, suggesting they expose extensive cross sections oceanic crust upper mantle. Oceanic megamullions comparable to continental...
Abstract Combined analyses of deep tow magnetic anomalies and International Ocean Discovery Program Expedition 349 cores show that initial seafloor spreading started around 33 Ma in the northeastern South China Sea (SCS), but varied slightly by 1–2 Myr along northern continent‐ocean boundary (COB). A southward ridge jump ∼20 km occurred 23.6 East Subbasin; this timing also was coeval to onset Southwest Subbasin, which propagated for about 400 southwestward from ∼23.6 ∼21.5 Ma. The terminal...
First‐order (transform) and second‐order ridge‐axis discontinuities create a fundamental segmentation of the lithosphere along mid‐ocean ridges, in slow spreading crust they commonly are associated with exposure subvolcanic upper mantle. We analyzed available morphological, gravity, rock sample data from Atlantic Ocean to determine whether consistent structural patterns occur at these constrain processes that control patterns. The results show their older, inside‐corner sides, both first‐and...

A characteristic early Pleistocene strong reflector is also identified, marks top extensive...
In this paper we observe that isomorphism classes of certain metrized vector bundles over P^1-{0,infinity} can be parameterized by arithmetic quotients loop groups. We construct an asymptotic version theta functions, which are defined on these quotients. Then prove the convergence and extend functions to symplectic interpret them as sections line infinite dimensional torus, discuss relations with Heisenberg groups, give multiplication formula.
To better understand the implications of ridge axis morphology for thermal and mechanical structure accreting plate boundaries, we examine mechanisms creation stress‐supported axial topography its dependence on parameters such as spreading rate, asthenosphere viscosity, thickness near axis. Three basic are considered: (1) asthenospheric upwelling in a narrow, steady‐state conduit beneath axis; (2) mantle flow stresses due to spreading, extending lithosphere, or melt segregation associated...
The Wenchuan earthquake on the Longmen Shan fault zone devastated cities of Sichuan, claiming at least 69,000 lives. We calculate that also brought Xianshuihe, Kunlun and Min Jiang faults 150–400 km from mainshock rupture in eastern Tibetan Plateau 0.2–0.5 bars closer to Coulomb failure. Because some portions these stressed have not ruptured more than a century, could trigger or hasten additional M > 7 earthquakes, potentially subjecting regions Kangding Daofu Maqin Rangtag strong...
[1] We report on a broad and unprecedented increase in seismicity rate following the M=9.0 Tohoku mainshock for M ≥ 2 earthquakes over inland Japan, parts of Japan Sea Izu islands, at distances up to 425 km from locus high (≥15 m) seismic slip megathrust. Such an was not seen 2004 M=9.1 Sumatra or 2010 M=8.8 Chile earthquakes, but they lacked networks necessary detect such small events. Here we explore possibility that changes are product static Coulomb stress transfer faults. use nodal...
The 11 March 2011 Tohoku Earthquake provides an unprecedented test of the extent to which Coulomb stress transfer governs triggering aftershocks. During 11–31 March, there were 177 aftershocks with focal mechanisms, and so change imparted by rupture can be resolved on aftershock nodal planes learn whether they brought closer failure. Numerous source models for mainshock have been inverted from seismic, geodetic, tsunami observations. Here, we show that, among six tested models, is a mean 47%...
