An 1867-Class Tsunami: Potential Devastation in the US Virgin Islands
Watlington, Roy A. (2006) An 1867-class tsunami: potential devastation in the US Virgin Islands. In: Caribbean Tsunami Hazard, (A. Mercado and P. Liu editors, ISBN 981-256-535-3), pp 255-267. AN 1867-CLASS TSUNAMI: POTENTIAL DEVASTATION IN THE US VIRGIN ISLANDS ROY A. WATLINGTON University of the Virgin Islands Abstract This paper describes the potential devastation that might result in the United States Virgin Islands if a tsunami identical to the Virgin Islands tsunami of November 18, 1867 were to occur today. Comparisons are made based on the reported runup in 1867 and also on the changes in population, coastal infrastructure, shipping activity, and in warning and mitigation systems for natural hazards. To find examples and make comparisons to modern demographics and infrastructure, the impacts of recent damaging hurricanes are presented. Recommendations are made on preparing for and mitigating the effects of a local tsunami. Background The 1867 Virgin Islands’ tsunami was initiated by an earthquake along a fault beneath the Virgin Islands Basin. This deep body of water is defined by the islands forming its topographic barriers. St. Thomas, St. John and the British Virgin Islands separate it from the Atlantic; St. Croix separates it from the Caribbean Sea, while Vieques and Culebra define its western boundary. To the east the Basin opens to the Atlantic through the Anegada Passage. It connects to the Caribbean’s Venezuela Basin through the Jungfern Passage and Grappler Channel. Interpretation of historic data and the accounts of witnesses have placed the earthquake’s epicenter at a location approximately equidistant from St. -
A Modified Sverdrup Model of the Atlantic and Caribbean Circulation
MARCH 2002 WAJSOWICZ 973 A Modi®ed Sverdrup Model of the Atlantic and Caribbean Circulation ROXANA C. WAJSOWICZ* Department of Meteorology, University of Maryland at College Park, College Park, Maryland (Manuscript received 9 October 2000, in ®nal form 6 August 2001) ABSTRACT An analytical model of the mean wind-driven circulation of the North Atlantic and Caribbean Sea is constructed based on linear dynamics and assumed existence of a level of no motion above all topography. The circulation around each island is calculated using the island rule, which is extended to describe an arbitrary length chain of overlapping islands. Frictional effects in the intervening straits are included by assuming a linear dependence on strait transport. Asymptotic expansions in the limit of strong and weak friction show that the transport streamfunction on an island boundary is dependent on wind stress over latitudes spanning the whole length of the island chain and spanning just immediately adjacent islands, respectively. The powerfulness of the method in enabling the wind stress bands, which determine a particular strait transport, to be readily identi®ed, is demonstrated by a brief explanation of transport similarities and differences in earlier numerical models forced by various climatological wind stress products. In the absence of frictional effects outside western boundary layers, some weaker strait transports are in the wrong direction (e.g., Santaren Channel) and others are too large (e.g., Old Bahama Channel). Also, there is no western boundary current to the east of Abaco Island. Including frictional effects in the straits enables many of these discrepancies to be resolved. -

ATOLL RESEARCH BULLETIN No. 139 THE ISLAND OF ANEGADA AND ITS k'LORA by W. G. D'Arcy Issued by THE SMITHSONIAN INSTITUTION Washington, D. C., U. S. A. February 16, 1971 THE ISLAND OF ANEGADA AND ITS nORA The island of Anegada in the British Virgin Islands is of interest because of its isolated location in relation to the Antillean island arc, its unusual topography amongst the Virgin Islands, and also the fact that it has received very little scientific attention. It now seems destined to join the list of islands which have succumbed to modern "development". This checklist combines past published reports with the writer's own collections and attempts to correct the nomenclature formerly applied to this flora. THE ISLAND Anegada is the northeasternmost of the British Virgin Islands and of the entire West Indian arc for that matter, vying with the rocky lighthouse, Sombrero, well to the southeast, as the closest Antillean approach to Europe. Its geographic coordinates are 18'45'N and 64°20'W, and it encompasses 14.987 square miles (Klumb and Robbins 1960) or about 33 square km. In shape it is a rather lumpy crescent with its long axis running approximately west by north and east by south. The nearest land, Virgin Gorda, some thirteen miles (ca 22 km) to the south and slightly west, is a prominent feature on the horizon (Fig. I), as is the mass of the other Virgins--Tortola, Camanoe and Jost Van Dyke-- further to the southwest. To the north and east there is no land for a long way. -

Dunne and B.E. Brown Introductory Description Anegada is a most unique island from many aspects. Northernmost of the American and British Virgin Islands and easternmost of the Greater Antilles, it is a flat limestone island, 17 km long and 4 km wide with a total area of about 14.94 square miles (9,567 acres 54 sq km), It is set aside from the other British Virgin Islands, being some 19 km from Virgin Gorda, its closest neighbour. It lies in distinct contrast to the volcanic and mountainous landscapes of the Virgin Group, with a maximum elevation of only 8 metres, To the north and east (windward side) the island is edged by extensive reefs beyond which stretches the Atlantic Ocean. On the leeward side, a shallow sea (2 to 8 m) separates Anegada from the main Virgin Island Group. His tory Schmburgk (1832) is the earliest authority on the island, having visited it in 1831 when he completed a most extensive survey. He writes: 'Of its history little is known; there is no likelihood that it was settled early. Ere Labat, the only early writer who speaks of the Lesser West India islands, observes, that aborigines used it as an occasional rendezvous, where they procured great quantities of conchs (~trombusgigas); and large piles of these shells are still to be seen at the east end of the island, but nowhere else ; which seems to prove decidedly that it was not permanently accupied, but merely resorted to from time to time. -

Tsunami Stratigraphy in a Salt Pond on St. Croix, US Virgin Islands
Tsunami Stratigraphy in a Salt Pond on St. Croix, US Virgin Islands Thesis Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of The Ohio State University By Paul Russell, B.S. Graduate Program in Earth Sciences The Ohio State University 2018 Thesis Committee: Derek Sawyer, Adviser Audrey Sawyer Matt Saltzman Copyright by Paul Russell 2018 Abstract Tsunamis pose a major threat to human health and safety in the Caribbean and coastal communities around the world. In order to constrain the recurrence interval of these natural disasters and help build resilience, sedimentary deposits from both paleotsunamis and those in the historical record must be identified and examined. Preservation of tsunami deposits is often poor, but coastal salt ponds, a common occurrence in the Caribbean, have been recognized as having the potential to capture tsunamites. This study examined <1m cores from the West End Salt Pond on the island of St. Croix, US Virgin Islands for evidence of inundation events. One deposit that showed several characteristics of an inundation event and was present in multiple locations across the pond was identified, and interpreted as having originated from the 1867 Virgin Island Tsunami. Deeper cores may reveal deposits from other tsunamis that have been identified in the region. ii Dedication I dedicate this to the faculty of ORCA, who first sparked my passion for science. iii Acknowledgements I would like to acknowledge my advisor Dr. Sawyer, who funded my time at Ohio State and provided me with the opportunity to travel to the Virgin Islands to do research. -

Bats of Anguilla, Northern Lesser Antilles
Occasional Papers Museum of Texas Tech University Number 270 24 October 2007 Bats of anguilla, northern lesser antilles HugH H. genoways, scott c. Pedersen, carleton J. PHilliPs, and linda K. gordon aBstract Five species of bats are known in the literature from Anguilla—Monophyllus plethodon, Brachyphylla cavernarum, Artibeus jamaicensis, Natalus stramineus, and Molossus molossus. These records are scattered in the literature as parts of simple reports of the species from the island or included in revisions of taxonomic groups that occur on the island, but the first com- prehensive study of bats of Anguilla is presented herein. In addition to providing morphometric and natural history information for the five species of bats previously known from the island, records of a species of bat new to the fauna of the island of Anguilla—Tadarida brasiliensis—are documented. Based on data from this study, the conclusion is drawn that the Anegada Passage has had only a limited impact as a zoogeographic barrier for the chiropteran faunas of the Greater and Lesser Antilles, if a perspective of the last 10,000 years is taken. Key words: Anegada Passage, Anguilla, Chiroptera, natural history, Tadarida brasiliensis introduction The island of Anguilla is located at the northern revisions of taxonomic groups that occur on the island end of the Leeward islands (18°13'12"N, 63°04'22"W), (Goodwin 1959; Schwartz and Jones 1967; Swanepoel with only its political dependency, Sombrero Island, and Genoways 1978), but no comprehensive study of lying further to the north (58 km northwest). Because bats of Anguilla has appeared. Our field studies added no bats have been reported from Sombrero Island, the a sixth species of bat—Tadarida brasiliensis—to the chiropteran fauna of Anguilla is the northern-most official total known from the island and we expect that population of bats in the Lesser Antilles.
