Strong Earthquakes Recurrence Times of the Southern Thessaly, Greece, Fault System: Insights from a Physics-Based Simulator Application

The recurrence time, Tr, of strong earthquakes above a predefined magnitude threshold on specific faults or fault segments is an important parameter, that could be used as an input in the development of long-term fault-based Earthquake Rupture Forecasts (ERF). The amount of observational recurrence time data per segment is often limited, due to the long duration of the stress rebuilt and the shortage of earthquake catalogs. As a consequence, the application of robust statistical models is difficult to implement with a precise conclusion, concerning Tr and its variability. Physics-based earthquake simulators are a powerful tool to overcome these limitations, and could provide much longer earthquake records than the historical and instrumental earthquake catalogs. A physics-based simulator, which embodies known physical processes, is applied in the Southern Thessaly Fault Zone (Greece), aiming to provide insights about the recurrence behavior of earthquakes with Mw ≥ 6.0 in the six major fault segments in the study area. The build of the input fault model is made by compiling the geometrical and kinematic parameters of the fault network from the available seismotectonic studies. The simulation is implemented through the application of the algorithm multiple times, with a series of different input free parameters, in order to conclude in the simulated catalog which showed the best performance in respect to the observational data. The detailed examination of the 254 Mw ≥ 6.0 earthquakes reported in the simulated catalog reveals that both single and multiple segmented ruptures can be realized in the study area. Results of statistical analysis of the interevent times of the Mw ≥ 6.0 earthquakes per segment evidence quasi-periodic recurrence behavior and better performance of the Brownian Passage Time (BPT) renewal model in comparison to the Poissonian behavior.

Improved The Behavior Of The Prevention Of Recurrence Of Hypertension On The Elderly Through Empowerment Support Group

Hypertension in the elderly can actually be prevented, but the lack of adequate knowledge about the elderly hypertension and prevention efforts are likely to increase the number of occurrence of hypertension and hypertension occurred so often repeated (relapse). With empowerment Support Group is expected to be an increase in prevention of recurrence behavior of hypertension in the elderly. The purpose of the study is to know the influence of the support group against the behavior of the elderly in the prevention of recurrence of hypertension at the village and subdistrict Bicak Trowulan Mojokerto. The design used was pre experiments with one group pre test and post testdesign. This research sample 24 elderly by using purposive sampling technique. Data collection through the pre test and post test using a questionnaire about the behavior of the elderly in the prevention of recurrence of hypertension. Intervention support group provided for 8 weeks. Data processing is started from the editing, coding, scoring and tabulating. then conducted a test of a different mode. The results showed there was a positive change in behavior in the prevention of recurrence of hypertensive elderly in the village of Trowulan subdistrict of Mojokerto Bicak. Empowerment Support group is effective in improving the behavior of the elderly in the prevention of recurrence of hypertensive diDesa Bicak subdistrict of Mojokerto Trowulan as much as 83.4%, because of the support group is a group that teaches the assistance and guiding the elderly behave healthy life which will result in reducing or eliminating personal and social problems.

Major Earthquakes Occur Regularly on an Isolated Plate Boundary Fault

The scarcity of long geological records of major earthquakes, on different types of faults, makes testing hypotheses of regular versus random or clustered earthquake recurrence behavior difficult. We provide a fault-proximal major earthquake record spanning 8000 years on the strike-slip Alpine Fault in New Zealand. Cyclic stratigraphy at Hokuri Creek suggests that the fault ruptured to the surface 24 times, and event ages yield a 0.33 coefficient of variation in recurrence interval. We associate this near-regular earthquake recurrence with a geometrically simple strike-slip fault, with high slip rate, accommodating a high proportion of plate boundary motion that works in isolation from other faults. We propose that it is valid to apply time-dependent earthquake recurrence models for seismic hazard estimation to similar faults worldwide.
