- Probabilistic seismic hazard analysis model for the Philippines | GEM Foundation
Publications Probabilistic seismic hazard analysis model for the Philippines Share Facebook LinkedIn Download 2020 | Peer-reviewed The Philippine archipelago is tectonically complex and seismically hazardous, yet few seismic hazard assessments have provided national coverage. This article presents an updated probabilistic seismic hazard analysis for the nation. Active shallow crustal seismicity is modeled by faults and gridded point sources accounting for spatially variable occurrence rates. Subduction interfaces are modeled with faults of complex geometry. Intraslab seismicity is modeled by ruptures confined to the slab volume. Source geometries and earthquake rates are derived from seismicity catalogs, geophysical data sets, and historic-to-paleoseismic constraints on fault slip rates. The ground motion characterization includes models designed for global use, with partial constraint by residual analysis. Shallow crustal faulting near metropolitan Manila, Davao, and Cebu dominates shaking hazard. In a few places, peak ground acceleration with 10% probability of exceedance in 50 years on rock reaches 1.0g. The results of this study may have utility for defining the design base shear in the National Structural Code of the Philippines.
- EuroPython Conference - GEM Foundation
News EuroPython Conference By: Jul 2, 2018 Share Facebook LinkedIn GEM’s Michele Simionato presented ‘Lessons Learned from Parallel Programming’ during the 2017 Conference on July 14 held in Rimini, Italy. He was joined by IT Team members Paolo Tormene and Armando Scarpati in the week long event that featured five parallel tracks covering more than 200 sessions and attended by hundreds of developers across Europe. Michele, a Senior Software Developer at GEM, shared his hard-learned knowledge gained in several years of parallel programming covering performance and ways to measure it; memory usage; data transfer and ways to reduce data transfer time; and how to debug parallel programs and useful libraries. He also shared practical examples both in enterprise and scientific programming (importing CSV files in a database and numerical simulations respectively). The initial part of the talk was pedagogical, advocating the convenience of parallel programming in a small, single machine environment; while the second part focused more on advanced programming discussing a few things to know when writing parallel programs for medium sized clusters. EuroPython is the largest Python conference in Europe organized by the EuroPython Workgroups (WGs), reporting directly to the EuroPython Society Board. The conference series was started in 2002 in Charleroi, Belgium and considered to be the first major Python conference run entirely by volunteers. No images found. GALLERY 1/0 VIDEO RELATED CONTENTS

- Nigel Priestley Seminar 2018 - GEM Foundation
News Nigel Priestley Seminar 2018 By: Jul 12, 2018 Share Facebook LinkedIn The Fourth International Nigel Priestley Seminar took place on May 24 and 25 within the premises of the CAR College Auditorium in Pavia. The Seminar is named in honour of Prof. Nigel Priestley, co-founder of the ROSE School in 2001. The Seminar is an occasion for Master and PhD students of the Understanding and Managing Extremes (UME) Graduate School of the IUSS (Istituto Universitario di Studi Superiori) to present and discuss their research work to an audience of international experts in the field of Earthquake Engineering, Engineering Seismology and Hydrological, Weather, Geological, Chemical and Environmental Risks. On May 25 Alejandro Calderón, Physical Risk Engineer at GEM, delivered a presentation titled “Towards a Unified Earthquake Loss Assessment Model for Central America and the Caribbean”, which he also presented in Greece in June at the 16th European Conference on Earthquake Engineering. As part of his doctoral research, Alejandro is interested in the state of physical earthquake risk in the region of Central America and the Caribbean. Within the framework of the GEM CCARA project, Alejandro contributed in the risk assessment for the region by deriving exposure models for these countries combining census datasets and satellite imagery. The results presented in the seminar included the country earthquake risk profiles for the region that are part of the Global Risk Model currently in development by the GEM Foundation. Each profile contains valuable information about the exposed human and economic capital, the level of earthquake hazard and the expected average annual losses for each country. Alejandro also presented preliminary results on the assessment of possible future risk scenarios for which the spatial distribution of buildings, their structural typologies and earthquake vulnerability were inferred from the construction evolutive process observed in Central America and other regions of the world. In addition to standard presentations on research work carried out within the Programmes of the School, the annual Seminar features also the tradition of inviting a prominent scientist to deliver a keynote lecture on a given contemporary and highly relevant topic in the field of Earthquake Engineering and Engineering Seismology. At this year’s event, the keynote lecture entitled “Twenty-three years from Kobe - Japanese research and practice on collapse, performance, functionality, and resilience” was delivered by Professor Masayoshi Nakashima, Professor at the University of Kyoto. As it is customary at each end of the event, the Seminar concluded with the awarding of a prize to one of the most prominent scientists studying in the field of earthquake engineering. This year, the sixth edition of the ROSE School Prize has been awarded to Professor Anil K. Chopra. Below, an excerpt of the motivation: “Anil K. Chopra, Professor Emeritus at the University of California at Berkeley, is a renowned leader in structural dynamics and earthquake engineering.
