Skyquake

A skyquake is a mysterious loud sound that seems to come from the sky. People often describe it as a banging noise or a sound like a horn. This sudden noise can sometimes make buildings shake or cause walls and ceilings to vibrate.

Those who hear a skyquake usually don't know what caused it, which makes the experience feel strange and puzzling. Skyquakes have been reported in many places around the world. They are often heard near lakes or other bodies of water.

Reports of skyquakes have come from the North Sea, the Ganges, Canada, Colombia, Japan, Finland, Vanuatu, Australia, Italy, Ireland, India, The Netherlands, Norway, Tierra del Fuego in Argentina, the United Kingdom, the United States, Mexico, Malaysia (particularly Ipoh), and Indonesia (particularly Jakarta and Java). These sounds continue to puzzle scientists and people who hear them.

Local names

Different places have special names for the skyquake. In Bangladesh, it is called Barisal guns. In France, people say "bombes de mer" or "canons de mer". In Indonesia, it is known as dentuman or suara tembakan meriam, meaning "the sound of cannon fire". Italy calls it "brontidi" or "rombo". In Japan, it is named "uminari", which means "cries from the sea".

People all over the world have heard these sounds, from Australia to the United States. Early explorers like Meriwether Lewis and William Clark heard these mysterious sounds on their trips. Some cultures, like the Iroquois, thought these booms were from the Great Spirit. The names "mistpouffers" and "Seneca guns" come from Seneca Lake, New York, and describe the sound like far-off thunder or cannon fire.

Hypotheses

A skyquake is a loud noise that seems to come from the sky. Scientists do not know exactly what causes these sounds, but they have some ideas. Some think small meteors entering the atmosphere make loud booms. Others believe it could be gas explosions under lakes or underground.

Some ideas include military planes making sonic booms, shallow earthquakes, or weather like distant thunder. Others suggest solar activity or waves on rocky shores might be to blame. These ideas try to explain the puzzling sounds that sometimes occur in the sky.
