What is some information about "Skyquakes"?

Skyquakes have been a fairly well known phenomenon for quite some time. In fact the all famous Lewis and Clark expedition was witness to such an Earthly oddity on July 4, 1808 while exploring the Rocky Mountains. Skyquakes are quite similar to Earthquakes except they seem to come out of no where and sound much like muffled thunder or have even been described as cannon fire. Most skyquake witnesses report that it’s most definitely not an earthquake, but seems to come out of the sky. The Lewis and Clark expedition made a record of hearing these bizarre skyquakes in their journal, let’s take a look at some of that entry.
"Since our arrival at the Falls we have repeatedly heard a strange noise coming from the mountains in a direction a little to the north of west. It is heard at different periods of the day and night, sometimes when the air is perfectly still and without a cloud, and consists of one stroke only, or five or six discharges in quick succession. It is loud, and resembles precisely the sound of a six pound piece of ordnance at the distance of three miles."
The most popular experiences to skyquakes are the Barisal Guns of India and the Moodus Noises of Connecticut.
Skyquakes or mystery booms are unexplained reports of a phenomenon that sounds like a cannon or a sonic boom coming from the sky. They have been heard in several locations 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, Italy and in Drogheda, Ireland.
They have been reported from: on an Adriatic island in 1824; Western Australia, South 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.
The terms "mistpouffers" and "Seneca guns" both originate in Seneca Lake, NY, and refer to the rumble of artillery fire. James Fenimore Cooper, author of The Last of the Mohicans, wrote "The Lake Gun" in 1850, a short story describing the phenomenon heard at Seneca Lake, which seems to have popularized the term.
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 causing sonic booms.
**** Gas: escaping from vents in the Earth's surface. With lakes, bio gas from decaying vegetation trapped beneath the lake bottoms suddenly bursting forth. This is plausible, since Cayuga Lake and Seneca Lake are two large and deep lakes. Explosive release of less volatile gases generated as limestone decays in underwater caves.
**** Military aircraft (though it cannot explain occurrences of the phenomenon which predate supersonic flight).
**** In some cases, they have been associated with earthquakes. Earthquakes may not hold as a general cause because these sounds are often unaccompanied by seismic activity, other than the vibrations induced by sound.
**** In North Carolina, one speculation is that they are the sound of pieces of the continental shelf falling off into the Atlantic abyss. However, the Atlantic abyss is not only too far away from the east coast, but the Atlantic ridge is the result of very slow moving tectonics and couldn't produce such sounds given the frequency of their occurrence.
**** A recent explanation is that the noise is very distant thunder which has been focused anomalously as it travelled through the upper atmosphere.
**** Underwater caves collapsing, and the air rapidly rising to the surface.
**** Possible resonance from solar and/or earth magnetic activity inducing sounds.
**** Volcanic eruptions
On April 2, 1978, there was a loud explosion on Bell Island which caused damage to some houses and the electrical house wiring in the surrounding area. Two cup-shaped holes about two feet deep and three feet wide marked the major impact. A number of TV sets in Lance Cove, the surrounding community, exploded at the time of the blast. It was initially thought to be caused by ball lightning. Meteorologists confirmed that atmospheric conditions at the time were not conducive to lightning. The boom was heard 55 kilometers away in Cape Broyle. The impact occurred in the Bickfordville area, on the southwestern side of the island.
The incident was investigated by John Warren and Robert Freyman from Los Alamos Scientific Laboratory, in New Mexico. It has been speculated that, due to the two men's place of work, they were investigating a secret weapons test and were military attachés. However, reacting to data received from the Vela satellites, they were in fact investigating a "superbolt" - an unusually large bolt of lightning, lasting an unusually long time: about a thousandth of a second.
A documentary that aired on the History Channel about electromagnetic pulse weapons investigated the speculation that the incident may have been a result of top secret experiments. It was postulated that either the Soviet or the U.S. governments were the cause of the 'attack' and that it involved high energy beams focused into the ionosphere that were attracted by the iron in abandoned mines. In the Skeptoid podcast The Bell Island Boom, presenter Brian Dunning dismissed that theory, stating, "Although iron is magnetic and can be magnetized, natural iron ore has its molecules jumbled in every direction and rarely happens to have a significant magnetic field, certainly not strong enough to divert or attract a particle beam." Although some have pointed out that the natural oolitic iron ore on Bell Island is magnetic due to its hematite content, such ore does not generate a magnetic field, for the reasons Dunning discussed.
