AB - ABSTRACT: Plate tectonics and the seismic gap hypothesis provide the framework for long-term earthquake forecasting of plate boundary earthquakes. Unfortunately, detailed examination reveals that earthquake recurrence times and rupture length vary between successive earthquake cycles in the same subduction zone. Furthermore, larger coseismic slip is commonly associated with larger rupture length. Hence, large earthquake occurrence in subduction zones is characterized by variability in: (1) recurrence times, (2) rupture length, and (3) coseismic slip. These facts, plus many other observations, indicate that there are significant spatial variations in the "strength" of the plate interface. One simple description of these variations and their role in the earthquake cycle is the asperity model, where the large strong regions of the plate interface are called asperities, and the large earthquakes occur when the large asperities break. The asperity model of earthquake occurrence is able to qualitatively explain several features of large plate boundary earthquakes. To go beyond general qualitative notions, I pose the following scientific test: are the observed asperity distributions and a simple model of their interaction self-consistent with the above three observed features of large earthquake occurrence? The distribution of the major asperities along plate boundary segments has now been determined for several subduction zones. Rupture process studies of adjacent large and great earthquakes have provided reliable estimates of the along-strike asperity lengths and separations for several adjacent asperities in the Kurile Islands, Colombia, and Peru subduction zones. The simplest mechanical model for asperity interaction is to idealize two adjacent asperities as frictional sliders that are connected by main springs to the upper plate, by a coupling spring to each other, and maintain frictional contact with a conveyer belt (the lower plate) that moves with a constant velocity. An "earthquake" occurs when the net force on the asperity frictional slider reaches some specified level. The failure force and spring constants are determined by the observed asperity distribution and simple models of elastic interaction. Two different macroscopic failure criteria are used. This simple mechanical model displays a remarkable range of behavior from simple to complex. When the two asperities are identical in all their properties, sequences of identical "earthquakes" are produced. For the more realistic case of non-identical asperities, "earthquake" sequences show great variety. Using system variables from the observed asperity distributions, the "earthquake" sequences typically display: (1) variable recurrence times, (2) variable rupture length, i.e. a combination of single-asperity and double-asperity failures, and for one of the failure criteria (3) larger coseismic slip for double-asperity failures. Statistical summaries of thousands of simulated "earthquake" sequences for asperity pairs in the Kuriles, Colombia, and Peru subduction zones are broadly consistent with the observed features of large earthquake occurrence in these subduction zones. The main conclusion is that the asperity model provides a self-consistent explanation for: fault zone heterogeneity, the rupture process, and recurrence times and rupture mode of large earthquake sequences via a simple model for adjacent asperity interaction. In addition, a conclusion independent of any particular model for fault zone heterogeneity is that simple deterministic models of fault zone interaction can explain complex patterns of large earthquake occurrence in subduction zones.

AB - ABSTRACT: The trends delineated by D and (super 18) O contents of water discharges, from a wide range of geothermal and volcanic systems along convergent plate boundaries around the Pacific, point to the existence of a common magmatic component with a narrow range of delta D values of -20+ or -10 per mil. The delta D values for these waters, which are generally associated with andesitic magmatism, are well above those of -65+ or -15 per mil suggested for mantle water. The most likely source for this "andesitic" water is recycled seawater. It enters the subduction system in the form of porewater, or as the water of hydration in the clay minerals of accumulated marine sediments and is carried to the source region of arc magmas on the top of the subducting slab. Contributions from the continental and altered oceanic crusts appear to be minor, those from the mantle very minor (less than 1%). Large proportions of other components (CO2, N2 and probably Cl) in volcanic and, by implication, geothermal fluid discharges along convergent plate boundaries are likely to be also of predominantly subducted marine origin. Rather than being due to water rock isotope exchange within the crust, (super 18) O shifts in high temperature waters from thermal systems along convergent plate boundaries may largely reflect varying degrees of mixing with, in addition to D, (super 18) O enriched (+10+ or -2 per mil), and thus isotopically "pre-shifted", andesitic waters. Because of similarities, in terms of their formation conditions and D contents, with "evolved seawaters" associated with sedimentary basins and an accretionary prism in New Zealand, the term "devolved seawater" is proposed for magmatic waters produced from subducted sediments.
