Are there any fault lines in Maine?
This is different from California, for example, where earthquakes occur repeatedly along certain faults that are called “active.” This means that there are no particular “fault lines” in Maine that are related to the modern earthquakes we have.
When was Maine’s last earthquake?

How many earthquakes have happened in Maine?
Most Maine buildings, such as unreinforced brick and masonry structures, were not built to withstand the effects of a significant (magnitude 6 or higher) earthquake. The record of 507 historical and modern earthquake events has been compiled by the Maine Geological Survey for the years 1747 to 1992.
Was there an earthquake today near Maine?
There were no significant confirmed earthquakes in or near Maine in the past 24 hours.
Is Maine on a tectonic plate?
Maine sits in the middle of one of those geologic plates — the North American Plate — which acts as a buffer from the sometimes violent activity at either end of the plate. California, on the other hand, sits on one edge of that plate, which is rubbing against another tectonic plate.
Is Maine prone to earthquakes?
Seismic activity in Maine is typical of the Appalachian region of northeastern North America. There is a low but steady rate of earthquake occurrence. The largest earthquake recorded in Maine between 1747 and 1992 was near Eastport in 1904 with a Modified Mercalli intensity estimated at VII.
Do earthquakes happen in Maine?
But Maine does have earthquakes. There is a history of continual, low-level activity in the state, with larger ones every once in a while. Hundreds of earthquakes are recorded since 1766, and many more went unrecorded before modern instruments were installed in 1975.

What is the largest earthquake in Maine?
The largest accurate measurement was on June 15, 1973 from an earthquake just on the Quebec side of the border from northern Oxford County, Maine, with a Richter magnitude of 4.8 (Johnston, 1995). Most Maine earthquakes are of small magnitude.
What causes earthquakes in Maine?
Seismic Activity The earthquakes are presumably caused by modern stress being released occasionally along zones of weakness in the earth’s crust, but a more specific cause for the earthquake activity is not known. Most Maine earthquakes are of small magnitude. Many are too small to feel.
How many earthquakes happen a year in Maine?
Since 1975, Maine has had about one magnitude 3.0-3.9 earthquake every year, and a magnitude 4 earthquake every 10 to 15 years or so.
