Presentation Transcript

  1. Pelatihan : Techniques in Active Tectonic Study Juni 20-Juli 2, 2013 Instruktur: Prof. J Ramon Arrowsmith (JRA) Dari Arizona State University (ASU) - US Tempat Pelaksanaan: Ruang Pangea, Laboratorium Gempabumi (LabEarth) – Puslit Geoteknologi LIPI dan Kuliah lapangan akan dilakukan disekitar Sesar Lembang, Jawa Barat. * Lebih jelas baca TOR/KAK dan daftar acara

  2. 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

  3. 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 https://ondemand.azpm.org/videoshorts/watch/2009/7/30/kuat-ua-tree-ring-lab/

  4. Cape Suckling, Alaska: diminished growth due to tree shaking and tilting in the 1964 Alaska earthquake Sheppard and Jacoby, 1989

  5. Significant decrease in growth rate in winter 1812 helps with interpretation of location of 1812 earthquake in southern California Sheppard and Jacoby, 1989

  6. 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

  7. Ground shaking effects

  8. damages during the 2006 Yogyakarta Earthquake in Prambanan Temple Suryolelono et al., 2009

  9. Suryolelono et al., 2009 damages during the 2006 Yogyakarta Earthquake in Prambanan Temple

  10. 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

  11. 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

  12. 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
