This paper examines the possible causes of collapse of a primary school in San Giuliano, Italy, in the 2002 Molise earthquake, which killed 27 students and one teacher. It also considers the general sources of seismic vulnerability of school buildings in Italy prior to the introduction of new seismic zonation and new seismic codes in 2003. In addition to incomplete seismic zonation and inadequa...

The degree of hazard due to landslide in any region is difficult to assess manually. An automated system having capability to correlate causes contributing automated landslide hazard is expected to be an efficient alternative. The objective of this paper is to explain LHAZ (Landslide Hazard Automated Zonation) system, an automated system that has been developed to determine the intensity and ex...

abstract this survey accomplished for asessment and mechanism recognition of chenaran watershed landslide effective factors and its zonation based via lim model. primarily recognized effective factors, through studing and field survey and evaluated by landslide index method(lim) then based on their weight in model, landslide hazard zonation was done.then evaluated this model competence in zonat...

Geological disaster causes loss of lives and damage to man-made and natural stuctures. In this paper, a coupling method with optimal combination weighing law and extension model was established. Based on dynamic impact factors such as forest coverage, annual average rainfall, topography and gemorphogy, geologic structure, and type of rock and soil, the amount of disaster points and human engine...

We experimentally examined plant zonation in a previously unstudied Chilean salt marsh system to test the generality of mechanisms generating zonation of plants across intertidal stress gradients. Vertical zonation in this system is striking. The low-lying clonal succulent, Sarcocornia fruticosa, dominates the daily flooded low marsh, while intermediate elevations are dominated by the much tall...

The Government of Madagascar plans to increase marine protected area coverage by over one million hectares. To assist this process, we compare four methods for marine spatial planning of Madagascar's west coast. Input data for each method was drawn from the same variables: fishing pressure, exposure to climate change, and biodiversity (habitats, species distributions, biological richness, and b...
