Earthquake

The Maine Geological Survey says all of Maine has a moderate risk for earthquake. While Maine has experienced numerous measurable earthquakes in the last 100 years, none have caused substantial damage. The largest recorded earthquake in Maine was estimated to be a 5.9 magnitude that occurred near Eastport in 1904.

The most seismically active regions of Maine are the area along the eastern side of Passamaquoddy Bay, the Dover-Foxcroft/Milo area, southwestern Maine, and the Portland/Lewiston region.

Strong seismic activity that occurs in New Hampshire can affect people living in western Maine; seismic activity in Quebec along the Saint Lawrence can affect northwestern Maine.

Earthquake Safety:

Check for hazards in the home:

Fasten shelves securely to walls.
Place large or heavy objects on lower shelves.
Store breakable items such as bottled foods, glass, and china in low, closed cabinets with latches.
Hang heavy items such as pictures and mirrors away from beds, couches, and anywhere people sit.
Secure a water heater by strapping it to the wall studs and bolting it to the floor.
Repair any deep cracks in ceilings or foundations.
Get expert advice if there are signs of structural defects.

Identify safe places both indoors and outdoors:

Under sturdy furniture such as a heavy desk or table.
Against an inside wall.
Away from where glass could shatter around windows, mirrors, pictures, or where heavy bookcases or other heavy furniture could fall over.
In the open, away from buildings, trees, telephone and electrical lines, overpasses, or elevated expressways.

What to do AFTER an Earthquake:

Be prepared for aftershocks. Although smaller than the main shock, aftershocks cause additional damage and may bring weakened structures down. Aftershocks can occur in the first hours, days, weeks, or even months after the quake.
Help injured or trapped persons.
Give first aid where appropriate.
Do not move seriously injured persons unless they are in immediate danger of further injury. Call for help instead.

If you experience what you believe to be an earthquake in Maine

Please report it to the Maine Geological Survey. This helps geologists determine if and where the quake has occurred.

The behavior of pets may change dramatically after an earthquake. Normally quiet and friendly cats and dogs may become aggressive or defensive. Watch animals closely. Leash dogs and place them in a fenced yard.
