Landscape Evolution in Cebu, Central Philippines: The Impact of Sea Level, Social History, and Tectonism on Cultural Landscapes
Location: Tokioka Room, Moore 319; UHM
When: Tuesday, March 20, 3:00 P.M.
| Précis: |
Landscape formation is often discontinuous and punctuated by rapid change, and cultural landscapes may be fragmented and found in chronological and spatial mosaics rather than continuous progressions. Two periods of human occupation in the Carcar area of the central Philippines are discussed relative to these effects. Pleistocene evolution of landscapes in Cebu is a complex array of uplifted fossil coral reef platforms that form the lower benches of the central cordillera of the island. These formed during prior periods of high sea level, and their present altitude has been increased by periodic tectonic uplift. Submarine fossil coral reef platforms are components of this landscape evolution, and at least two at depths of 20 meters and 60 meters below present sea level formed in the mid- to late Pleistocene. A submarine flank-margin cave, Marigondon cave, formed in the 20 meter reef platform when subaerial in the period from 80,000 to 12,000 ybp. More recent Holocene era sea level change, rising by 1.8 meters above present sea level in the period from 2,000 to 5,500 ybp altered coastal terrain and constrained human settlement to the upper extent of the present coastal plain. Subsequent upland degradation has buried the mid-Holocene shoreline below 2-3 meters of colluvial deposits. These two contexts for human settlement are situated in the complex mosaic of the present geography of Cebu.

Dr. Peterson’s archaeological fieldwork during the past several decades has been undertaken in East and SE Asia, Hawai’i, the Western Pacific, and North America. His research has included studies of the origins of agriculture, terrestrial geomorphology, artifact characterization, Spanish contact and colonialism, and 19th century Texas. Much of his current research is centered on reconstructing and interpreting the dynamic articulation of natural and cultural landscapes in the central Philippines.
