According to volcanologists, this eruption was triggered by tectonic spreading of the Kivu rift causing the ground to fracture and allow lava to flow from ground fissures out of the crater lava lake and possibly from a deeper conduit nearer Goma. At the time of writing, scientists are concerned that the continuing high level of seismic activity indi- cates that the tectonic rifting may be gradually continuing. Scientists agree that volcano monitoring and contingency planning are essential for forecasting and responding to fu- ture trends. The relatively small loss of life in the January 2002 eruption (less than 100 deaths in a population of 500,000) was remarkable, and psychological stress was reportedly the main health consequence in the aftermath of the eruption.

  • Establishing a Holocene Tephrochronology for Western Samoa and Its Implication for the Re-Evaluation of Volcanic Hazards
    ESTABLISHING A HOLOCENE TEPHROCHRONOLOGY FOR WESTERN SAMOA AND ITS IMPLICATION FOR THE RE-EVALUATION OF VOLCANIC HAZARDS by Aleni Fepuleai A thesis submitted in fulfilment of the requirements for the degree of Doctor of Philosophy Copyright © 2016 by Aleni Fepuleai School of Geography, Earth Science and Environment Faculty of Science, Technology and Environment The University of the South Pacific August 2016 DECLARATION Statement by Author I, Aleni Fepuleai, declare that this thesis is my own work and that, to the best of my knowledge, it contains no material previously published, or substantially overlapping with material submitted for the award of any other degree at any institution, except where due acknowledge is made in the next. Signature: Date: 01/07/15 Name: Aleni Fepuleai Student ID: s11075361 Statement by Supervisor The research in this thesis was performed under my supervision and to my knowledge is the sole work of Mr Aleni Fepuleai. Signature Date: 01/07/15 Name: Dr Eleanor John Designation: Principal Supervisor ABSTRACT Samoan volcanism is tectonically controlled and is generated by tension-stress activities associated with the sharp bend in the Pacific Plate (Northern Terminus) at the Tonga Trench. The Samoan island chain dominated by a mixture of shield and post-erosional volcanism activities. The closed basin structures of volcanoes such as the Crater Lake Lanoto enable the entrapment and retention of a near-complete sedimentary record, itself recording its eruptive history. Crater Lanoto is characterised as a compound monogenetic and short-term volcano. A high proportion of primary tephra components were found in a core extracted from Crater Lake Lanoto show that Crater Lanoto erupted four times (tephra bed-1, 2, 3, and 4).

  • The Natural Choice for Wildlife Holidays Welcome
    HOLIDAYS WITH 100% FINANCIAL PROTECTION The natural choice for wildlife holidays Welcome After spending considerable time and effort reflecting, questioning what we do and how we do it, and scrutinising the processes within our office and the systems we use for support, I am delighted to say that we are imbued with a new vigour, undiminished enthusiasm, and greater optimism than ever. My own determination to continue building on the solid foundation of twenty years of experience in wildlife tourism, since we started from very humble beginnings – to offer what is simply the finest selection of high quality, good value, tailor-made wildlife holidays – remains undaunted, and is very much at the core of all we do. A physical move to high-tech office premises in the attractive city of Winchester leaves us much better connected to, and more closely integrated with, the outside world, and thus better able to receive visitors. Our team is leaner, tighter, more widely travelled and more knowledgeable than ever before, allowing us to focus on terrestrial, marine and – along with Dive Worldwide – submarine life without distraction. In planning this brochure we deliberately set out to whet the appetite, and make no mention of either dates or prices. As the vast majority of trips are tailored to our clients’ exact requirements – whether in terms of itinerary, duration, standard of accommodation or price – the itineraries herein serve merely as indications of what is possible. Thereafter, you can refine these suggestions in discussion with one of our experienced consultants to pin down your precise needs and wants, so we can together create the wildlife holiday of your dreams.

Cuicocha volcano is part of Ecuador’s Western Andean volcanic cordillera together with some 16 other active volcanoes as result of interaction of the Nazca oceanic plate with the Caribbean and South American continental plates. Cuicocha represents the fourth most dangerous active volcano in Ecuador with its volcanic activity is represented by the upheating of its waters and a fumarolic activity expressed by gas bubbles and some dead vegetation due to the emission of CO2 through the soils. Monitoring Cuicocha volcanic crater lake has been a priority task due to the presence of a considerable amount of population living within a 20 km radius of Cuicocha caldera rim.

In many instances, however, data on past events is scarce or incomplete, such that the evaluation of possible future risks and/or the planning of adequate countermeasures can only be done with rather limited certainty.

  • Volcanic Hazards • Washington State Is Home to Five Active Volcanoes Located in the Cascade Range, East of Seattle: Mt
    CITY OF SEATTLE CEMP – SHIVA GEOLOGIC HAZARDS Volcanic Hazards • Washington State is home to five active volcanoes located in the Cascade Range, east of Seattle: Mt. Baker, Glacier Peak, Mt. Rainier, Mt. Adams and Mt. St. Helens (see figure [Cascades volcanoes]). Washington and California are the only states in the lower 48 to experience a major volcanic eruption in the past 150 years. • Major hazards caused by eruptions are blast, pyroclastic flows, lahars, post-lahar sedimentation, and ashfall. Seattle is too far from any volcanoes to receive damage from blast and pyroclastic flows. o Ash falls could reach Seattle from any of the Cascades volcanoes, but prevailing weather patterns would typically blow ash away from Seattle, to the east side of the state. However, to underscore this uncertainty, ash deposits from multiple pre-historic eruptions have been found in Seattle, including Glacier Peak (less than 1 inch) and Mt. Mazama/Crater Lake (amount unknown) ash. o The City of Seattle depends on power, water, and transportation resources located in the Cascades and Eastern Washington where ash is more likely to fall. Seattle City Light operates dams directly east of Mt. Baker and in Pend Oreille County in eastern Washington. Seattle’s water comes from two reservoirs located on the western slopes of the Central Cascades, so they are outside the probable path of ashfall. o If heavy ash were to fall over Seattle it would create health problems, paralyze the transportation system, destroy many mechanical objects, endanger the utility networks and cost millions of dollars to clean up. Ash can be very dangerous to aviation.
