In the Central American Republic of El Salvador the Rio Lempa divides the eastern third of the country from the rest. In its lower course it flows through a large coastal plain, built up in geologically recent times by river deposits and sediments from the volcanic chain in the north (San Vicente and the volcanic group of the east). From west (Balsam range) to east (Colinas de Jucuarán) this plain has a length of about 100 km. and a width of 20 km. Some 20 years ago the nearly flat land, which slopes only very slightly from the volcanic chain to the Pacific coast, was still heavily wooded, but since then most of the forest has been cleared away for cotton crops, only leaving tiny patches of the original vegetation. In this process a number of archaeological sites were revealed, especially east of the Rio Lempa, in the department of Usulután.

Abstract We propose a cross-validated seismic hazard (CVSH) method contrasting time-independent and dependent models via the Poisson and Weibull probability cumulative distributions. Based on the upper-limit spectral accelerations retrieved from the time-dependent models, we infer that in the memoryless Poisson approach, the selected lifetime of buildings is location-dependent rather than a fixed classical value of 50 years for all sites. All models compute the seismic hazard for magnitudes M 5-7.83 by the influence of the interface subduction zone in El Salvador at three locations, the Capital City San Salvador, the Port of Acajutla on the coastline, and Arcatao Town in the North of the country returning average spectral accelerations with less than 10% differences in all cases.

AbstractThis paper examines the actions of one Salvadorean priest – Padre David Rodríguez – in one parish – Tecoluca – to underscore the importance of religious leadership in the rise of El Salvador's contentious political movement that began in the early 1970s, when the guerrilla organisations were only just beginning to develop. Catholic leaders became engaged in promoting contentious politics, however, only after the Church had experienced an ideological conversion, commonly referred to as liberation theology. A focus on one priest, in one parish, allows for generalisation, since scores of priests, nuns and lay workers in El Salvador followed the same injustice frame and tactics that generated extensive political mobilisation throughout the country. While structural conditions, collective action and resource mobilisation are undoubtedly necessary, the case of religious leaders in El Salvador suggests that ideas and leadership are of vital importance for the rise of contentious politics at a particular historical moment.
