Earthquakes shake Arnold/Callaway for the fourth time

By  | 

ARNOLD, Neb. (KNOP) - A second, stronger earthquake in Custer County around 6:40 a.m. Tuesday morning. USGS confirmed the earthquake with a magnitude of 3.7 on the Richter Scale, southeast of Arnold.

Things shook a little harder, and a little longer this time, according to Justin Stockall of Arnold (who spoke about Monday's first earthquake).

This earthquake was 5 km, or 3.11 miles deep. The was the same measurable depth of Monday's earthquake.

An additional earthquake was confirmed at 6:55 a.m. which was weaker and just North of Arnold. It registered a magnitude of 2.5 meaning it was more that 10 times weaker than the first.

A third earthquake occurred at 10:49 a.m. This one was near the same area and depth as the first earthquake. It registered a magnitude of 3.1.

Officials at NEIC (National Earthquake Information Center) in Golden, Colorado, said Monday that there is nothing to worry about.

Justin Stockall of Arnold remembers waking up suddenly. "At first I thought it was thunder shaking the house but it was moving differently. It was the weirdest sensation."

Stapleton was listed as the focal point of the earthquake, but the USGS (United States Geographical Survey) lists Stapleton as 22.99 miles east south east of the epicenter. Most vibrations were felt in the Arnold/Callaway area.

Don Blakeman, a geophysicist with NEIC (National Earthquake Information Center) in Golden, Colorado, said that there is nothing to worry about. He said Monday morning's quake will not affect anything. 3.11 miles below the surface, the quake is a result of a earthquake by definition, according to Blakeman; "Stresses build up, and they become enough that they release energy."
