Earthquake activity in the greater New York City area: Magnitudes, seismicity, and geologic structures

Abstract Earthquakes recorded by stations of the Lamont-Doherty seismic network in the greater New York City area are analyzed to determine magnitudes and the relationship between seismicity and geologic structures. Between 1974 and 1983, the configuration of stations in this region remained relatively stationary and the type of recording devices (visual drum recorders and 16-mm photographic recorders) did not change. This distribution of stations and recording devices allows for a uniform measurement of magnitudes and seismicity. Magnitudes of these earthquakes are determined by comparing amplitudes and signal duration measured from high-frequency (5 to 10 Hz) data recorded by the local network with mbLg and ML determined from data at frequencies near 1 Hz. During the period of time studied (nearly 10 yr), 61 earthquakes were located in this region, but none of these earthquakes exceeded 3.0 on the mbLg scale. The largest event (mbLg = 3.0) occurred in the Coastal Plain province of northern New Jersey. The magnitude threshold for uniform detection of events throughout this region during the period of time studied is estimated to be mbLg = 1.6. With events below this threshold removed from the catalog of network seismicity, we find that about half of the earthquakes studied occurred within 10 km of the Ramapo fault system. This fault system lies about 30 km northwest of New York City and has been interpreted by several investigators to be the most active fault system in the greater New York City area. However, earthquakes at least as large as those recorded near the Ramapo fault were located as far as 50 km from this fault (and within 20 km of New York City), in geologic structures that surround the Newark basin. While the Ramapo fault can by no means be ruled out as a possible source zone for earthquakes in the greater New York City area, the geologic structures associated with most (if not all) earthquakes in this region are still unknown. Thus, the cause of earthquakes in this region remains an enigma.

The Relationship

This study aimed to analyze the changes in the 10 major categories of women’s healthcare services (WHSs) in Shanghai (SH) and New York City (NYC) from 1978 to 2017, and examine the relationship between these changes and maternal mortality ratio (MMR). Content analysis of available public policy documents concerning women’s health was conducted. Two indicators were designed to represent the delivery of WHSs: The essential women’s healthcare service coverage rate (ESCR) and the assessable essential healthcare service coverage rate (AESCR). Spearman correlation was used to analyze the relationship between the two indicators and MMR. In SH, the ESCR increased from 10% to 90%, AESCR increased from 0% to 90%, and MMR decreased from 24.0/100,000 to 1.01/100,000. In NYC, the ESCR increased from 0% to 80%, the AESCR increased from 0% to 60%, and the MMR decreased from 24.7/100,000 to 21.4/100,000. The MMR significantly decreased as both indicators increased (p < 0.01). Major advances have been made in women’s healthcare in both cities, with SH having a better improvement effect. A common shortcoming for both was the lack of menopausal health service provision. The promotion of women’s health still needs to receive continuous attention from governments of SH and NYC. The experiences of the two cities showed that placing WHSs among policy priorities is effective in improving service status.

The Relationship

The relationship between social movements and formal organizations has long been a concern to scholars of collective action. Many have argued that social movement organizations (SMOs) provide resources that facilitate movement emergence, while others have highlighted the ways in which SMOs institutionalize or coopt movement goals. Through an examination of the relationship between Occupy Wall Street and the field of SMOs in New York City, this article illustrates a third possibility: that a moment of insurgency becomes a more enduring movement in part through the changes it induces in the relations among the SMOs in its orbit.

Economic And Social Impacts

Saturday, 18 December 2010 was the first of a two day complete closure of all London area airports due to freezing temperatures and approximately five inches of snow. A week later on December 26th, New York City area airports closed in a similar manner from the sixth largest snowstorm in NYC history, blanketing the city approximately twenty inches of snow. Both storms grounded flights for days, and resulted in severe delays long after the snow stopped falling. Both London and NYC area airports produced risk communications to explain the necessity for the closures and delays. This short flash news report examines, in turn, the risk communications presented during the airport closures. A background is provided to understand how the risk perceptions differ between London and NYC publics. Finally, it compares and contrasts the perceptions of the decision making process and outcomes of the closures, which continue to accumulate economic and social impacts.

The Relationship

In this semi-biographical short story, the relationship between James Baldwin and Attorney General Robert F. Kennedy, and its culmination in their epic confrontation in New York City on 24 May 1963, is portrayed through the lens of an unidentified fictive narrator. In the midst of heightened racial tensions, Baldwin has been tasked with bringing together a delegation of prominent Black US personalities to meet with the Attorney General and share their views on the measures necessary to combat segregation and racism. The meeting has barely begun before the naivety of the administration’s view of the national situation becomes clear, and the atmosphere in the room grows increasingly strained. “The Fire Inside” has never before appeared in print. An earlier version of the story was broadcast by Swedish Radio on 29 November 2019.

Gains And Losses

This book offers the first quantitative long-term historical analysis of the migratory, winter, and breeding avifaunas of any New York City natural area—Van Cortlandt Park and the adjacent Northwest Bronx—and spans the century and a half from 1872 to 2016. Only Manhattan’s Central and Brooklyn’s Prospect Parks have published even lightly annotated cumulative species lists, last updated in 1967, and the most recent book addressing the birdlife of the New York City area was published more than 50 years ago. Addressed are the 301 Bronx, New York City and New York City area species known to have occurred within the study area, plus another 70 potential additions. These are contrasted with their status in adjacent Riverdale, the entire Bronx, Central and Prospect Parks, New York City, plus Long Island, Westchester, and Rockland Cos. The history of the 123 known study area breeding species are tracked from 1872—only 20 years after Audubon’s death in Manhattan—complemented by unique quantitative breeding data from Van Cortlandt Park censuses from 1937 to 2015. Gains and losses of breeding species are tracked and discussed as an expanding New York City inexorably extinguished unique habitat, offset only slightly by addition of two large reservoirs. Comparisons are provided with analogous data from heavily monitored Central and Prospect Parks. The tradeoffs in attempting to managing an urban park area for mass recreation at the same time as conserving its natural resources are highlighted.
