Earthquakes and Fault Lines in Northern New Jersey
Here are some of the entries:
Ringwood Boro, Passaic County, 1/2/2016, 5:58 am, Lat. 41.1298, depth= 8.38 km. Magnitude: 2.07, Location: 2.4km NW of Ringwood, N.J.
In the map above, I brought in some shape files that I downloaded several years ago. The January 2, 2016 earthquake location is shown by a green star. Light rail lines in red. Earthquake sites are shown by a color coded dot based on the magnitude of the quake. I used Jenkins-Box to assign the various ranges. The highest magnitude is in red. Each earthquake site shows the date of the quake and the magnitude. I also brought in fault lines (from a download of several years ago) and a raster file of elevations in NewJersey. The higher the location, the lighter the color. Notice that the non-electric light rail line that goes to Camden sits on the site of a prior earthquake.
Folks, do not make any decisions on this map. I am not a geologist. I am just having some fun with maps and I hope you find this information useful.
25 Earthquake Sites are within 500 Feet of a Fault: Analysis Done by ARGIS. A buffer of 500 Feet was set up around the fault shape file data. Those sites within this buffer are shown. They represent 13.1% of the total. Notice that southern NJ does not seem to have fault lines?
