[...]... and in Figure 1.3 inthe bar marked ‘‘Average.’’ The average central intercept is cal a.d 650, the 1sigma range is a.d 636–660, and the 2-sigma range is cal a.d 610–671 Those ranges are the most precise and accurate approximation for the dating of the final thatching ofthe roofs of Structures 1, 2, and 3, and for the eruption of Loma Caldera volcano and the abandonment oftheCerén site The author expresses... Another exceptional aspect ofCerén is the preservation of agricultural fields with the plants growing in them The maize fields are ridged, with clusters of three to five plants germinating in a single planting hole The plants themselves decomposed introduction 7 within months or perhaps years after being encased inthe volcanic ash, but fortunately the ash had enough consistency to preserve the form of. .. multidisciplinary .The archaeology is introduced inthe first chapter, beginning with the Precolumbian village called Cerén that functioned inthe southern Maya periphery It was a villageof commoners, and as such inthe minds of many students of Mesoamerica might be expected to be a rather poor group of households under the economic, political, and religious domination ofthe elite After all, the largest and presumably... are sufficient to indicate that theCerén sequence is dispersed primarily to the south and west ofthe vent The distribution of deposits oftheCerén sequence suggests that the eruptions that buried the site occurred during a period of northerly and easterly winds Thickness measurements at the northern edge oftheCerén site (Operation 4), where the sequence is figure 2.2 Location map ofCerén site, nearby... ofthe ground surface, possible structural damage to their houses, and possibly other precursory activities inthe vicinity ofthe awakening volcanic vent may have provided ample warning to residents ofCerénofthe cataclysm that was soon to occur and given them the opportunity to escape beforethe arrival ofthe lethal pyroclastic surges of Unit 1 The frantic departure of residents ofCerén during... within the Ministry of Education, and ofthe nongovernmental organization Patronato Pro-Patrimonio Cultural are then described That is followed by an overview ofthe organization of the book and how the chapters integrate with the wealth of data, text, pre-eruption site reconstruction, and images available on the CD-ROM An Interactive Guide to Ancient Cerén: BeforetheVolcanoErupted and the Cerén. .. available on the CD-ROM An Interactive Guide to Ancient Cerén: BeforetheVolcanoErupted Thus, we believe this represents the best solution to the problems of data and interpretation availability, soaring printing costs, and the need to share a great amount of research data from a variety of disciplines at theCerén site This volume begins with volcanology, geophysics, and paleoethnobotany in Part I... to the east, of 1 to as much as 5 cm The location of fissures and faults within about 20 m of the top ofthe bank of the Río Sucio, their alignment roughly parallel to the bank of the river, and their extensional character and consistent down-to -the- east displacements suggest that the fissures resulted from slumping ofthe west bank ofthe Río Sucio Available stratigraphic and morphologic evidence indicates... that the timing ofthe dated events differs by less than a decade This demonstrates that the differences among the individual dates result from stochastic variation of isotopic decay and analysis, rather than from differences inthe dated events These reasons justified averaging the dates using a statistical function inthe CALIB program The results of that averaging are presented in Table 1.2 inthe row marked... during the earliest stages ofthe eruption would explain both the absence of remains of human occupants in structures excavated to date and the fact that residents abandoned most of their possessions Conclusions TheCerén sequence consists of a series of pyroclastic-fall and pyroclastic-surge beds deposited during fluctuating but essentially continuous eruptive activity At least the upper part oftheCerén . 238 BeforetheVo lcanoErupted the ancient cerén village in central america Edited by Payson Sheets university of texas press austin Tseng 2002. 3.21 12:14 6272 Sheets / BEFORE THE VOLCANO ERUPTED.
