There were no immediate reports of injuries or damage and no tsunami warning was issued.
There are no major construction projects, and the shaking seems to be located right around the township building, according to officials.

ESA's GOCE mission has delivered the most accurate model of the 'geoid' ever produced. Red corresponds to points with higher gravity, and blue to points with lower gravity.
Anything that has mass has a gravity field that attracts objects toward it. The strength of this field depends on a body's mass. Since the Earth's mass is not spread out evenly, this means its gravity field is stronger in some places and weaker in others.
The magnitude 9.0 Tohoku-Oki temblor in March was the most powerful earthquake to hit Japan and the fifth-most powerful quake ever recorded. To see how the temblor might have deformed the Earth there, scientists used the Gravity Recovery and Climate Experiment (GRACE) satellites to analyze the area's gravity field before and after the quake.
The researchers found the Tohoku-Oki quake reduced the gravity field there by an average of two- millionths of a gal by slightly thinning the Earth's crust. In comparison, the strength of the gravitational pull at the Earth's surface is, on average, 980 gals. (The gal, short for Galileo, is a unit of acceleration; one gal is defined as one centimeter per second squared.)
Measuring devices this morning have picked up a large earthquake swarm, usually a tell-tale sign of a potential volcanic eruption.
The Icelandic Government last month announced it was increasing monitoring Katla, which is one of Europe's most feared volcanoes, following a consistent and strengthening spike of tremors and quakes.
And last week, officials at the Iceland Meteorological Office confirmed a series of smaller eruptions had occurred in July strengthening fears of an imminent, much larger, eruption.
Evidence gathered by geophysicists showed the magma had risen to the height of the glacier ice above the volcano causing it to melt.
They said the high seismic tremors recorded on July 8 and 9 confirmed Katla had become active and started small eruptions.
