Description:

Abstract:

The New Jersey Geological Survey Digital Geodata Series DGS04-1 dataset shows earthquakes that had epicenters in New Jersey. This data has 204 earthquakes with epicenters in New Jersey. Most are minor with magnitudes ranging from 0.4 to 5.3 and depths up to 25 km below sea level. Earthquakes with magnitude of 0 (zero) implies that the magnitude is unknown.

Following earthquake added since Oct. 2, 2017 version:

1) 3.5 km NW of Keansburg, NJ on 11-08-2017, 08:33:44 (EST), Magnitude 1.38, Depth 4.34 km.

Purpose:

To provide information on earthquakes which had epicenters in New Jersey.

Attribute_Accuracy:

Attribute_Accuracy_Report: unknown

Logical_Consistency_Report: unknown
Completeness_Report:

Some earthquake locations were in Latitude and Longitude degrees and minutes, rounded to the nearest minute and converted to decimal degrees. Others were in decimal degree and they were converted to NJ State Plane coordinate system. Earthquakes with magnitude of 0 (zero) implies that the magnitude is unknown.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Instrumental epicenter accuracy is estimated to be within 0.0 degrees to 0.5 degrees and non-instrumental accuracy ranges from 0 degrees to 2.0 degrees (Stover, 1984 and NEIC).

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:

A formal accuracy assessment of the vertical positional information in the data set has either not been conducted, or is not applicable.

Lineage:

Process_Step:

Process_Description:

Data on earthquake epicenters were gathered from the regional seismic network at Lamont Doherty Observatory, Bulletins of the Northeast Seismic Network, New England Seismic Network, information from the U.S. Geological Survey and other books and reports. A table was created with this information in Microsoft Excel software. The tabular information was then imported into ESRI ArcMap software and converted into a shapefile.

Most of the earthquakes in this database were recorded with seismic equipment. The older earthquakes, included were not recorded by seismic equipment but were documented by NEIC, and the USGS. Instrumental epicenter accuracy is estimated to be within 0.0 degrees to 0.5 degrees and non-instrumental accuracy ranges from 0 degrees to 2.0 degrees (Stover, 1984 and NEIC). Earthquakes with magnitude of 0 (zero) implies that the magnitude is unknown.
