Update 22:26 UTC: Interesting read from USGS about earthquakes in the Eastern USA

Why should people in the eastern U.S. be concerned about earthquakes?
1) Severe earthquakes have occurred in the Eastern U.S.:
In November of 1755, an earthquake with an estimated magnitude of 6.0 and a maximum intensity of VIII occurred about 50 miles northeast of Boston, Massachusetts. Boston was heavily damaged. Other strong earthquakes recorded in the continental US were centered in southeastern Missouri near the border with Arkansas, Kentucky and Tennessee.  In the winter of 1811-1812, a series of three powerful earthquakes of magnitudes about 7.0 to 7.8 and hundreds of aftershocks occurred near New Madrid, Missouri. These shocks were so strong that observers reported that the land distorted into visible rolling waves. They changed the course of the Mississippi River, created a vast area of ground deformation and liquefaction features; and they were felt widely along the east coast of the U.S. 800 to 1000 miles away.  Because the surrounding area was mostly undeveloped at the time, few deaths were reported and these events stirred relatively little attention then. In August of 1886, a strong earthquake occurred in Charleston, South Carolina. Magnitude is estimated at 6.8 to 7.2. Much of the city of Charleston was damaged or destroyed. Earthquakes in the East are not confined to these areas; they have been recorded in every State east of the Mississippi. Damaging earthquakes have occurred historically in nearly every eastern State.

2) Earthquakes of the same magnitude affect larger areas in the East than in the West:
The size of the geographic area affected by ground shaking depends on the magnitude of the earthquake and the rate at which the amplitudes of body and surface seismic waves decrease as distance from the causative fault increases. Comparison of the areas affected by the same Modified Mercalli intensity of ground shaking in the 1906 San Francisco, California, the 1971 San Fernando, California, the 1811-12 New Madrid, Missouri, and the 1886 Charleston, South Carolina, earthquakes shows that a given intensity of ground shaking extends over a much larger area in the Eastern United States. Ground shaking affects a larger area because amplitudes of seismic waves decrease more slowly in the east than in the west as distance from the causative fault increases.

Update 15:41 UTC: For those among you downloading our iOS or Android app, you will unfortunately not find this earthquake in the eq list because our system only picks up M2.8 or bigger. Using the I FELT IT screen at the bottom of the app can be done without a problem.

Update 15:40 UTC: Latest calculated location of the epicenter

Update 15:37 UTC: USGS reports now a Magnitude of 2.7 at a depth of 6.25 km. Our data have been created to keep the earthquake in our list 🙂

Update 15:27 UTC: Our earthquake list has problems with this earthquake because our system does normally not list earthquakes below M2.8 and ... it is currently 2.7 but before it jumped from M2.6 to M3.1. These updates are normal as the scientists are re-calculating all data.

Update 14:58 UTC: Based on the present earthquake parameters (Magnitude, Depth, Population, etc) and our experience with earthquake damage impact, earthquake-Report.com does not expect any damage from this earthquake.

Understanding and reading about it now, it seemed like either an unusually strong vibration from heavy equipment, or incredibly mild but noisy earth shimmy. Or figured noise had to do with Millville Lake dam, the huge metal pipe or metal grate being thumped by something, but what would have thumped it, I didn’t know, just the sound.

It was rather nerve racking. The kitties were concerned a bit but settled right down. I checked the entirety of the home to be certain it was ok and that I did not miss something mechanical, which I did not. The entire place shook and rumbled!

Small to moderate slides in roadside cuttings and unsupported excavations. Small water and sand ejections and localized lateral spreading adjacent to streams, canals, lakes, etc.
    MMI IX (Violent shaking) ?
    Structures Many low standard buildings destroyed. Ordinary workmanship buildings heavily damaged, some collapse. Reinforced masonry or concrete buildings damaged, some with partial collapse. Buildings and bridges designed and built to resist earthquakes damaged in some cases, some with flexible frames seriously damaged. Damage or permanent distortion to some buildings and bridges, designed and built to normal use standards. Houses not secured to foundations shifted off. Brick veneers fall and expose frames. Environment : Cracking of ground conspicuous. Landsliding general on steep slopes.
