Published on

"Hazard Mitigation: Volcán Barú, Panama"
By Julie A. Herrick
A review of mitigation efforts at the potentially active volcano, Volcán Barú. Historical seismicity, geologic mapping, lahar flow modeling, recent studies, and international efforts have developed hazard preparedness within the Chiriqui Province of western Panama."

Transcript of "Hazard Mitigation: Volcán Barú, Panama"

  1. 1. Hazard Mitigation: Volcán Barú, Panama International Collaboration Julie A. Herrick Returned Peace Corps Volunteer Panama
  2. 2. Outline: Volcanic Hazards  Worldwide  Events and Products  Strongest Impact  Monitoring Methods Invitation to Panama  Natural Hazards Volcán Barú Hazard Zones,USGS 2007.  Authorities  Mitigation Activities Nationwide  Decade for Natural Hazard Reduction  Volcanic hazards in western Panama  Field Methods  Frequency of events  Ongoing Collaboration
  3. 3. Volcanism WorldwideLess than half of the world’sactive volcanoes are currentlymonitored.In under-developed countries:•82% of active volcanolocations•86% of volcano-related deathsbetween 1600 AD and 1982(Lockwood, 2010; Chester, 1993) (Siebert et al. 2010) Volcán Barú, Panama
  4. 4. Volcanic Hazards Worldwide Events Each Century~60 events that pose a threat to aviation~60 events related to lava flows~20 events related to lahars, pyroclastic flows/surges~0.5-1.0 events related to structural collapse (e.g. sector failure)(Chester, 1993) Unzen Complex above Shimabara, Japan (Takashi Yamada, 1992).
  5. 5. Volcanic Hazards Worldwide Fatal Events (1600 to 1982)0.4% from lava flows19% from tsunamis30% from lahars, avalanches, pyroclastic flows/surges(Chester, 1993) Ashfall from Pinatubo, Philippines. (USGS, 1991). Buried to the roofline, children standing on a school’s roof above lahar flows from Pinatubo, Philippines. (USGS, 1991).
  6. 6. Hazard Forecasting (Ewert et al. 2005) “Keeping Monitoring as Simple as Practical” (Swanson, 1995)
  7. 7. The Republic of Panama*
  8. 8. Panama’s Three PrimaryVolcanic Centers Canal
  9. 9. Mitigation Authorities University of Panama Sinaproc  National System of Civil Protection Senacyt  National Council of Science and Technology CEPREDENAC  Center of Natural Disaster Prevention in Central America OSOP  Seismic Observatory of Western Panama
  10. 10. Seismic HazardsOrange and red points are ≥6.0 magnitude events. (UTP & Sinaproc)
  11. 11. Volcanic Hazards: Chiriquí ProvinceInternational effort of IAVCEI, “Decade for Natural Disaster Reduction”  Pro-active regional participant, CEPREDENAC  Significant, recent events:  Mount St. Helens, Nevado de Ruiz, Cameroon, Pinatubo, Unzen
  12. 12. First Report: Identification and Assessment Mitigation at Volcán Barú, 1992  Volcanic region supports major agriculture and tourism  “Economic risk”  Davíd, the 2nd largest populated center in the country is downslope  “Vulnerability”  High precipitation rates proximal to the edifice  “Natural climate”  Established general stratigraphy of the volcano with K/Ar dating  Calculated the lower limit for the volcano’s age  Formalized action plan  Inter-agency communication in Panamanian
  13. 13. Hazard ZonesProducts from assessments bythe US-based VolcanoDisaster Assistance Program,“VDAP.” (Sherrod et al. 2007)
  14. 14. Crisis Response “Earthquake activity beneath Panamas Baru Volcano in May 2006 served as a reminder that the slumbering volcano, long thought to be dormant by local residents, might one day reawaken. English News Panama 3/5/2008”Collaboration: Senacyt/US AID providing funding USGS consulting and VDAP visit, equipment loan, and training Sinaproc Universtiy of Panama Local community members
  15. 15. Volcán Barú’s Timeline (Sherrod et al. 2007)
  16. 16. Volcán Barú: Collapsed Edifice(1) Caisán Collapse; (2) Barriles Collapse Original Photo by K. Johnson (1995)
  17. 17. Mount St. Helens: Collapsed EdificePhotographed on Sept. 10, 1980; the collapsed profile is outlined in black.
  18. 18. CommunicationInformational meetings held with local authorities,Civil Protection of the Chiriqui Province, Sept., 2009. Ron and Kim Miller at an avalanche outcrop, Gariché Ranch, Feb., 2009.
  19. 19. Field MethodsIn the stratigraphy:A: The Barriles Deposit,the “young” deposit.B: Sedimentary beds offine sand and clay.C: The Caisan Deposit,the “old” unit. Scarp height: 15 meters
  20. 20. Volume Calculations Barriles Volume: 34 km^3 Caisan Deposit: 53 km^3
  21. 21. Radiocarbon Sampling:Barriles Deposit 3-120 meters thick: Sample GPS072 8,000 ±30 ybp Sample GPS309 8,590 ±50 ybpCaisán Deposit 4.5-128 meters thick: Sample GPS065 43,350 ±750 ybp Sample GPS248 >43,500 Discovering wood fragments from a broken and buried forest. Barú, Panama 200.
  22. 22. International CollaborationIn Panama: Seed money for seismic monitoring Professional publications disseminating new data Volcanic history has become well-established New research possibilities have appeared Increased hazard awareness for the public

Lockwood •Geology Graduate Seminar Participants Mount St. Helens from Johnston Ridge (Hinderman, 2004)."It should be emphasized that the short-term hazards posed by volcanoes are balanced by benefits of volcanism and related processes over geologic time." -- Robert I.Tilling, USGS, 1985.
