- A 4.4 magnitude earthquake struck 6 miles outside of Dover, Delaware.
- Social media users in Washington D.C. and New York City said they felt the quake.
- The strongest shaking near the earthquake’s epicentre could have caused moderate damage, according to the USGS.
Delaware got hit with a 4.4 magnitude earthquake late Thursday afternoon, and shaking was felt as far away as New York City.
The quake’s epicentre was just over 6 miles (10 km) from Dover, Delaware and hit at a depth of 4.3 miles (7 km).
The map above show’s the quake’s reach. The rings around its epicentre – represented by the yellow star on the map – show the varying degrees of intensity of the shaking. The sea-green ring around the epicentre represents level six shaking, according to the United States Geologic Survey (USGS).
Lucy Jones, a seismologist at the USGS, said on Twitter that Intensity VI shaking could “damage poorly built structures,” and “throw things off of shelves.” The strongest shaking at the quake’s epicentre was measured at Intensity VII, which can cause moderate damage, according to the USGS.
Though some New Yorkers reported feeling the quake, the shaking that hit the region was measured as Intensity II, which is characterised by the USGS as weak with no potential for damage.
Earthquakes are uncommon on the East Coast, and are much less intense than those on the West Coast. But they are typically felt over a larger area, according to the USGS.
