ABSTRACT We report tremor or local earthquake signals that occurred during the propagation of Love and Rayleigh waves from the 2012 Mw 8.6 Sumatra earthquake in three intraplate regions: Yellowstone, central Utah, and Raton basin (Colorado). These surface waves likely also dynamically triggered seismic activity along the western boundary of the North American plate, and did not trigger seismic activity in the central and eastern United States. We report additional potential dynamic triggering in the three aforementioned intraplate regions by surface waves from 37 additional large earthquakes, recorded between 2004 and 2017. These surface waves’ transient stresses generally appear to trigger tremor in seismically, volcanically, and hydrothermally active regions, such as Yellowstone, if the waves also arrive from favorable directions. These stresses do not appear to be decisive factors for triggering local earthquakes reported for the Raton basin and central Utah, whereas, surface waves’ incidence angles do appear to be important there.


Subject Prospects for Syria to end-2019 Significance Fighting is continuing in north-western Syria's Greater Idlib region between forces loyal to President Bashar al-Assad and remaining rebels, despite recent Russian claims of a negotiated ceasefire. Meanwhile, the United States has not vacated the north-east, as US President Donald Trump indicated last December. The economic gains of 2017 and 2018 are foundering amid stiffened US sanctions on both Syria and Iran, a key economic partner.

AbstractThis article examines transnational connections between African American emancipation in the United States and Chinese and Indian indenture within the British Empire. In an era of social upheaval and capitalist crisis, planters and colonial officials envisioned coolies as a source of uninterrupted plantation labor. This vision was often bound to the conditions of African American emancipation. In British Honduras, colonial officials sought to bring emancipated African Americans to the colony as labor for sugar plantations. When this project failed, interest turned toward indentured Chinese labor managed by white planters from the U.S. South. In India’s North-Western Provinces, the outbreak of famine came to be seen as a “kindred distress” to the crisis in Lancashire’s textile industry. Unemployed English factory workers were seen as suffering from famine due to the scarcity of slave-produced cotton, just as colonial subjects suffered from scarcity of food. While some weavers in the North-Western Provinces were taken into the coolie trade, the emigration of unemployed Lancashire weavers was looked to as a possible alternative to indenture. Drawing upon archives in Australia, Belize, Britain, India, and the United States, this article explores connections between seemingly disparate histories. By focusing upon their interrelation, this article locates the formation of crisis not in raw materials, but rather within a transnational struggle over racialized labor exploitation, or what W.E.B. Du Bois called the “dark and vast sea of human labor.”

Organized crime is spreading like a global virus as mobs take advantage of open borders to establish local franchises at will. That at least is the fear, inspired by stories of Russian mobsters in New York, Chinese triads in London, and Italian mafias throughout the West. As this book explains, the truth is more complicated. The author has spent years researching mafia groups in Italy, Russia, the United States, and China, and argues that mafiosi often find themselves abroad against their will, rather than through a strategic plan to colonize new territories. Once there, they do not always succeed in establishing themselves. The book spells out the conditions that lead to their long-term success, namely sudden market expansion that is neither exploited by local rivals nor blocked by authorities. Ultimately the inability of the state to govern economic transformations gives mafias their opportunity. In a series of matched comparisons, the book charts the attempts of the Calabrese 'Ndrangheta to move to the north of Italy, and shows how the Sicilian mafia expanded to early twentieth-century New York, but failed around the same time to find a niche in Argentina. The book explains why the Russian mafia failed to penetrate Rome but succeeded in Hungary. A pioneering chapter on China examines the challenges that triads from Taiwan and Hong Kong find in branching out to the mainland. This book is both a compelling read and a sober assessment of the risks posed by globalization and immigration for the spread of mafias.

This forum builds on the discussion stimulated during an online salon in which the authors participated on June 25, 2020, entitled “Archaeology in the Time of Black Lives Matter,” and which was cosponsored by the Society of Black Archaeologists (SBA), the North American Theoretical Archaeology Group (TAG), and the Columbia Center for Archaeology. The online salon reflected on the social unrest that gripped the United States in the spring of 2020, gauged the history and conditions leading up to it, and considered its rippling throughout the disciplines of archaeology and heritage preservation. Within the forum, the authors go beyond reporting the generative conversation that took place in June by presenting a road map for an antiracist archaeology in which antiblackness is dismantled.
