Mistpouffers
Encyclopedia
Mistpouffers are unexplained reports that sound like a cannon or a sonic boom
. They have been heard in many waterfront communities around the world such as the banks of the river Ganges in India, the East Coast
and inland Finger Lakes
of the United States, as well as areas of the North Sea
, Japan
and Italy
; and sometimes away from water. Names (according to area) are:
They have been reported from: on an Adriatic island in 1824; Western Australia
& Victoria
in Australia; Belgium
; frequently on calm summer days in the Bay of Fundy
, Canada; Lough Neagh
in Northern Ireland
; Scotland
; Passamaquoddy Bay
, New Brunswick
& Cedar Keys, Florida & Franklinville
, New York in 1896 & in northern Georgia
in the United States
.
Their sound has been described as being like distant but inordinately loud thunder while no clouds are in the sky large enough to generate lightning. Those familiar with the sound of cannon fire say the sound is nearly identical. The booms occasionally cause shock waves that rattle plates. Early white settlers in North America were told by the native Haudenosaunee (Iroquois
) that the booms were the sound of the Great Spirit
continuing his work of shaping the earth.
One explanation for why they are usually heard near water is that inland communities are often too noisy to hear these booms. Their origin has not been positively identified. They have been explained as:
Sonic boom

One explanation for why they are usually heard near water is that inland communities are often too noisy to hear these booms. Their origin has not been positively identified. They have been explained as:
- Meteors entering the atmosphere.
- Gas:
- Gas escaping from vents in the Earth's surface.
- With lakes, natural gas from decaying vegetation trapped beneath the lake bottoms suddenly bursting forth.
