More than a decade after Dellamora’s remarks, a collective dread evident in literature and film has not abated; rather, it has perhaps intensified. -

Therefore, a new universal severity classification scheme for natural 9 disasters is developed and is supported by data. This universal system looks at the severity of disasters based on the 10 most influential impact factor and gives a rating from zero to ten; zero indicates no impact and ten is a world-wide 11 devastation. This universal system is for all types of natural disasters, from lightning strikes to super volcanic eruptions 12 and everything in between, that occur anywhere in the world at any time. -
Landslide Hazard Analysis for Hong Kong Using Landslide Inventory And
ARTICLE IN PRESS Computers & Geosciences 30 (2004) 429–443 Landslide hazard analysis for HongKongusing landslide inventory and GIS K.T. Chau*, Y.L. Sze, M.K. Fung, W.Y. Wong, E.L. Fong, L.C.P. Chan Department of Civil and Structural Engineering, The Hong Kong Polytechnic University, Yuk Choi Road, Hung Hom, Kowloon, Hong Kong, China Received 20 February 2002; accepted 5 August 2003 Abstract This paper presents a landslide-inventory-based and GIS-based framework for systematic landslide hazard analysis by employing historical landslide data in Hong Kong, coupling with geological, geomorphological, population, climatic, and rainfall data. Based on 1448 landslide data from 1984 to 1998, the diurnal and seasonal distributions of landslides are established and compared with the seasonal rainfall variation. The cumulative fatalities and injuries caused by landslides increase with the cumulative rainfall in HongKong,indicatinga strongcorrelation between rainfall and landslide consequences. The averageannual fatality and injury rates in HongKongcaused by landslide are 11.35 and 11.63, respectively. In terms of beinghit by a landslide, squatter areas and roads on HongKongIsland are at the highest risk. A frequency–volume relation for Hong Kong Island was established, and, using this relation, it was estimated that the return period of a 26,000 m3 landslide (the size of 1995 Shum Wan Road Landslide) is about 3.12 years. A hazard zonation map for HongKongIsland is established by usinghistorical data. The potential use of GIS technology to incorporate various layers of information is illustrated using Hong Kong Island as an example. Both landslide hazard and risk maps are proposed usingraster calculation. -

Received: 12 December 2013; in revised form: 27 January 2014 / Accepted: 10 February 2014 / Published: 20 February 2014 Abstract: Owing to the development of spaceborne synthetic aperture radar (SAR) platforms, and in particular the increase in the availability of multi-source (multi-band and multi-resolution) data, it is now feasible to design a surface displacement monitoring application using multi-temporal SAR interferometry (MT-InSAR). Landslides have high socio-economic impacts in many countries because of potential geo-hazards and heavy casualties. -
Educators Guide
EDUCATORS GUIDE 02 | Supervolcanoes Volcanism is one of the most creative and destructive processes on our planet. It can build huge mountain ranges, create islands rising from the ocean, and produce some of the most fertile soil on the planet. It can also destroy forests, obliterate buildings, and cause mass extinctions on a global scale. To understand volcanoes one must first understand the theory of plate tectonics. Plate tectonics, while generally accepted by the geologic community, is a relatively new theory devised in the late 1960’s. Plate tectonics and seafloor spreading are what geologists use to interpret the features and movements of Earth’s surface. According to plate tectonics, Earth’s surface, or crust, is made up of a patchwork of about a dozen large plates and many smaller plates that move relative to one another at speeds ranging from less than one to ten centimeters per year. These plates can move away from each other, collide into each other, slide past each other, or even be forced beneath each other. These “subduction zones” are generally where the most earthquakes and volcanoes occur.

Its complex basement structure was one major influence on Cenozoic tec- tonics; the rifting history of the north Australian margin was another. Fragments that rifted from Australia in the Jurassic collided with Sundaland in the Cretaceous and terminated subduction. From 90 to 45 Ma Sundaland was largely surrounded by inactive margins with localized strike- slip deformation, extension and subduction. At 45 Ma Australia began to move north, and subduc- tion resumed beneath Sundaland. At 23 Ma the Sula Spur promontory collided with the Sundaland margin. From 15 Ma there was subduction hinge rollback into the Banda oceanic embayment, major extension, and later collision of the Banda volcanic arc with the southern margin of the embayment. -

Crisis-Proof Manufacturing: How to Enable Long-Term Resilience COVID-19: a Litmus Test for Factory Resilience
Crisis-Proof Manufacturing: How to Enable Long-Term Resilience COVID-19: A Litmus Test for Factory Resilience “COVID-19 will likely follow the pattern of a broad crisis, resulting in a rather deep decline and a lengthy recovery.” – Harvard Business Review1 Crises like the COVID-19 pandemic are a litmus test for factory resilience. It exposes the known and unknown vulnerabilities of manufacturing systems and processes. It spurs manufacturers to reevaluate their factory resilience and rethink their crisis management seriously. The impact of COVID-19 on manufacturing processes and supply chain is highly disruptive and rippling. Global process manufacturers had to contend with the following challenges: Larger-scale supply disruptions. Manufacturers heavily dependent on sourcing materials from China, where the outbreak started, faced supply chain shortages.2 Significant demand reduction. The demand for automotive paints and coating, for example, has plummeted due to the pandemic.3 Drastic labor shortage. According to a French trade group ANIA study, food makers suffered a 22% loss in turnover globally due to the health crisis. Personal care and cosmetics manufacturers, on the other hand, had to shut down their firms due to lack of manpower.4 Costly delays. Pharmaceutical manufacturers that conduct clinical trials in China faced study disruptions and slower regulatory approvals.5 Reactive, Uncoordinated According to a study published in IEEE Engineering Management Review in July 2020, faculty members saw that the response of manufacturers to COVID-19 disruptions “has been largely reactive and uncoordinated.”6 To keep their operations running, some manufacturers have taken these temporary measures: Reactive cost-cutting such as overtime reduction, layoff, and discretionary spend cuts.1 Repurposing production to meet new demands goals, which can be costly and full of challenges.7 Partial operations capacity.
