Displaying 15 of about 16 resultsBenthic foraminifera from the South China Sea were studied to assess mass mortality and to monitor the composition and recovery of the benthic communities following the 1991 Mt Pinatubo ashfall. Surface distribution data from monitoring stations in the eastern South China Sea that were occupied during four cruises between spring 1994 and summer 1998 dis…
The June 1991 eruption of Mount Pinatubo, Philippines, was the second largest of the 20th century, emplacing 5--6 km 3 of pyroclastic-flow material and creating record high sediment yields on rivers draining the volcano. This thesis explores landscape response to and recovery from sediment loading in the 1991 eruption from the drainage basin scale to mo…
Rice farmers living in Sidoarjo Regency, Indonesia, awoke to a strange sight on May 29, 2006. The ground had ruptured overnight and was spewing out steam.
In the following weeks, water, boiling-hot mud and natural gas were added to the mixture. When the eruption intensified, mud started to spread over the fields. Alarmed residents evacuated,…
This book shares the findings not only of 18-month study of Concepcion but also two-month research on the situation in Central Luzon. The book focuses on the experience of Concepcion set against the backdrop of the lingering Mt. Pinatubo disaster in Region III to highlight opportunities and problems which may also exist in other municipalities similarly…
We determined vegetation structure and environmental variables in the Pasig-Potrero and Sacobia River systems on the east flank of Mount Pina-tubo, Luzon, Philippines, to define growth form and taxonomic groups that have influenced primary succession during the 15 yr since the eruption. We selected eight sites within an east-west range of 11.5 km, a nor…
Studying recovering plant biodiversity on Mount Pinatubo may provide valuable insights that improve our understanding of recovery of other ecosystems following disturbances of all types. Ongoing sheet and rill erosion coupled with mass waste events in the unstable pyroclastic flow deposits persist, effectively re-setting primary succession at micro-land…
The U.S. Agency for International Development (USAID) contracted with the U.S. Army Corps of Engineers (USACE) for the preparation of a comprehensive Recovery Action Plan (RAP). The RAP evaluates methods for controlling the sedimentation within eight river basins and the higher risk of flooding due to sediment-clogged drainage channels resulting from th…
The research aims to formulate disaster mitigation measures to reduce the damages caused by the volcanic eruption of Mount Gamalama and identify plans for evacuation routes in disaster-prone areas. Effective mitigation planning is needed for communities living in areas prone to disasters, including natural calamities such as volcanic eruptions. The deve…
The catastrophic eruption of Mt. Pinatubo in 1991 destroyed the forests that covered the peak and impacted the surrounding habitat over a broad area of central Luzon. Information on the mammal fauna of Mt. Pinatubo prior to the eruption is limited but documents a variety of native mammals. In 2011 and 2012, we surveyed mammals at localities along an ele…
The catastrophic 1991 eruption of Mt. Pinatubo in the Philippines inflicted severe damages to agriculture. It blanketed the landscape with a thick layer of unconsolidated silica-rich tephra. The remobilization of this material by rain produced debris flows (or lahars) that flooded and buried the lowland soils. Nearly three decades after this catastrophi…
Mt Pinatubo is located on the main island of Luzon in the Philippines. Its 1991 eruption is considered one of the most powerful volcanic explosions of the 20th century. The first victims of the eruption were the Aeta indigenous communities living on the slopes of the mountain. In 1999, approximately 50,000 people were still trying to resume life on the…
Our project focused on the investigation of the post-eruption hazards at Mt. Pinatubo (Philippines) using remote sensing data, and field observations of the 1991 eruption deposits. Through the use of multiple satellite images, field work, and the 1996/2000 PacRim data sets, we conducted studies of the co- and post-eruption hazards of the volcano due to…
In view of recovery of the livelihood and equitable regional development as well as the anticipated disasters due to flood and mudflow, the Government of the Philippines (GOP) requested a technical assistance to the Government of Japan (GOJ) to conduct a master plan formulation and feasibility study (the study) for sabo and flood control in the western…
More than 70% of the population in Indonesia live within 100km of one or more of the country’s 130 active volcanoes—that’s a staggering 175 million people. 8.6 million Indonesians live within 10km of an active volcano—well within the range of deadly pyroclastic flows.
After volcanic eruptions, communities are often encouraged to “build back better”. Bu…
This study explored the role Center for the Study of Active Volcanoes (CSAV) plays in the development of human resources of volcano observatory staff around the world using qualitative and quantitative approaches. The study design included a literature review, interviews with representatives from 10 national volcano observatories, and electronic su…
