Dendro and archeoseismologyOutline of this lecture

• Dendroseismology definition and examples

• Archeoseismology definition and examples

• -> Direct and indirect effects

Someof this lecture comes from this excellent book

Dendroseismology

• Application of tree ring analysis to earthquake studies: direct and indirect effects

• Need to look at numerous trees to check for broad response at the same time

Cape Suckling, Alaska: diminished growth due to tree shaking and tilting in the 1964 Alaska earthquake

Sheppard and Jacoby, 1989

Significant decrease in growth rate in winter 1812 helps with interpretation of location of 1812 earthquake in southern California

Sheppard and Jacoby, 1989

Archeoseismology“focuses on individual seismic events occuring at precise moments over relatively recent time (last few millenia), whose action affected precise locations—human constructions and their environment—which in turncan be studied through the archeological record” Stiros and Jones, 1996 quoted by McAlpin, 2006•Direct rupture damage•Ground shaking•Secondary phenomena

damages during the 2006 Yogyakarta Earthquake in Prambanan Temple

Kedulan Temple, Yogyakarta

• Buried by sequences of laharic deposits of Merapi volcano

• Occurrence of well-preserved tree in the main area of the temple at the same stratigraphic level of the base of the temple suggests the abandonment prior to burial, archaeological interpretation: not common to have tree in temple area

• Rubble at the base of the temple not related to the laharic flow nor any landslide, interpreted as cause of an earthquake that badly damaged the temple and force abandonment
