Last Week’s Tremors
We have been tracking activity over the last week closely in this region.
Tremors count eight events with a magnitude 2.5 or above centered nearby.
The most significant was a three-point-three magnitude earthquake registered on Aug. 7.
This event stands out as part of recent seismic history for locals here.
Magnitude and Energy
Magnitude measures the energy released at the source of the earthquake, USGS says clearly.
It replaces the old Richter scale which is being phased out slowly now.
Quakes between 2.5 and 5.4 magnitude are often felt but rarely cause much damage.
This information comes from Michigan Tech regarding their research on seismic data.
Safety Protocols for Earthquakes
If an earthquake strikes, it’s best to protect yourself right away immediately.
Here are tips from experts that apply regardless of your location today.
Pull over and stop if you’re in a car with the parking brake set.
Turn face-down and cover your head with a pillow while lying in bed.
If you are outdoors, stay away from buildings during sudden shaking events.
Stay inside and do not run to the outdoors or open spaces like that.
The best way is drop down to your hands and knees per officials say.
Aftershocks and Hazards
“Wherever you are, drop down to your hands and knees and hold onto something sturdy,” officials state clearly in their guidance documents.
Cover head and neck with arms if no shelter is available nearby at all.
Crawl under a sturdy table or interior wall away from windows generally.
“There can be serious hazards after an earthquake, such as damage to the building.”
Expect aftershocks to follow the main shock of an earthquake soon enough.
Be ready to Drop, Cover, and Hold On if you feel any subsequent tremors later on.
