STRANGE SOUNDS ARCHIVE · 2022
Meteor shockwaves rattled Pennsylvania, Mississippi and Utah, an unexplained blast-like disturbance was instrumentally detected on Washington’s Orcas Island, and another classic coastal “Seneca Gun” shook North Carolina’s Outer Banks. These are the most important mystery-boom events of 2022.
This curated archive documents the most significant mystery booms, loud unexplained bangs, meteor sonic booms, atmospheric shockwaves, skyquakes and unexplained rumblings reported worldwide during 2022.
Known industrial explosions, infrastructure failures, military detonations, wildfire-triggered munitions and other events with obvious conventional sources have been removed so that the archive focuses on phenomena genuinely relevant to the

Key facts — Mystery Booms 2022
- Meteors produced several of the year’s strongest booms. Major atmospheric shockwaves were documented over Pennsylvania, Mississippi, Utah and Gran Canaria.
- The January 1 Pittsburgh meteor was especially powerful. NASA estimated that the atmospheric event released energy equivalent to roughly 30 tons of TNT.
- Mississippi’s April fireball became an exceptionally well-documented case. The meteor produced loud booms and pressure waves, and meteorites were later recovered.
- Utah’s August mystery boom was ultimately linked to a meteor. Satellite observations and ground-based imagery supported an atmospheric shockwave rather than an earthquake.
- Orcas Island remains one of 2022’s most interesting unresolved cases. Seismic instruments detected the disturbance, but analysis showed that the signal behaved like an airwave rather than an earthquake.
- The Outer Banks produced another classic coastal mystery boom. No corresponding earthquake or obvious military source explained the October event.
What Were the Mystery Booms of 2022?
A mystery boom is a sudden explosion-like sound, pressure wave or rumbling disturbance whose source is not obvious when witnesses first experience it.
The term describes an observation rather than a single physical phenomenon. Very different processes can produce nearly identical reports of a loud bang, rattling windows, vibrating walls or a brief sensation resembling an earthquake.
Possible sources include:
- meteors and atmospheric bolides;
- supersonic aircraft;
- shallow earthquakes;
- quarry or mining blasts;
- industrial explosions;
- thunder and atmospheric pressure waves;
- cryoseisms or frost quakes;
- coastal acoustic phenomena traditionally described as Seneca Guns or skyquakes;
- and disturbances whose source remains unresolved.
For this archive, a loud explosion is not automatically a mystery boom. Known refinery fires, electrical failures, military explosive tests and other identified accidents are excluded because their causes are already understood.
The most useful mystery-boom cases are those in which eyewitness observations can be compared with seismic networks, weather data, meteor cameras, satellite instruments, infrasound sensors and official activity records.
How the 2022 Mystery Booms Are Classified
Strong instrumental, observational or official evidence identifies the physical source.
One explanation is strongly supported, although the complete chain of evidence is not conclusive.
The event is credibly documented, but available evidence does not establish a reliable cause.
The surviving evidence is too weak or contradictory for meaningful classification.
Important: “Unresolved” does not mean paranormal or scientifically inexplicable. It means only that the available evidence is insufficient to identify the source confidently.
January 2022 Mystery Booms
JANUARY 1 · SOUTHWESTERN PENNSYLVANIA, USA
Pittsburgh Meteor Airburst Produces Huge New Year’s Day Boom
Residents across southwestern Pennsylvania began 2022 with an extraordinary explosion-like boom that shook homes and generated widespread reports around the Pittsburgh region.
The source was not a conventional explosion or earthquake. Satellite observations detected the atmospheric flash, while infrasound instruments recorded the pressure wave generated by an incoming meteoroid.
NASA analysis estimated that the atmospheric event released energy equivalent to roughly 30 tons of TNT.
The Pittsburgh event is therefore one of the clearest examples from 2022 of a relatively small space rock producing an unexpectedly powerful disturbance at ground level.
Status: CONFIRMED
February 2022 Mystery Booms
FEBRUARY 8 · SOUTHERN NEW JERSEY / DELAWARE, USA
Powerful Mystery Boom Rattles South Jersey and Delaware
Residents across parts of southern New Jersey and Delaware reported a large explosion-like boom accompanied by shaking and rattling structures.
The event was widespread enough to generate questions about an earthquake, military aircraft or offshore activity.
No corresponding earthquake was detected. Military aircraft were operating offshore, but officials did not confirm a supersonic flight capable of conclusively explaining the reports.
With the main obvious possibilities investigated but no source established, the disturbance remains a useful example of a genuine regional mystery boom.
Status: UNRESOLVED
March 2022 Mystery Booms
MARCH 7 · ORCAS ISLAND, WASHINGTON, USA
Orcas Island Mystery Boom Is Recorded by Seismic Instruments — But Was Not an Earthquake
An intense predawn boom awakened residents of Orcas Island in Washington State and produced enough energy to be detected by nearby seismic instruments.
That might normally suggest an earthquake. Closer analysis, however, showed something unusual.
The signals propagated through the monitoring network in a manner more consistent with an airborne pressure wave than seismic energy moving outward through the ground.
Researchers were able to constrain the apparent source to the Orcas Island area, but no definitive cause was established.
This makes the event especially valuable: it was not merely an anecdotal boom heard by a few witnesses. It left an instrumental signature while still resisting a clear explanation.
Status: UNRESOLVED
April 2022 Mystery Booms
APRIL 27 · MISSISSIPPI / LOUISIANA, USA
Daylight Meteor Explodes Over Mississippi and Produces Powerful Booms
A fast-moving daylight fireball entered the atmosphere over the southern United States and generated loud explosion-like sounds heard across parts of Mississippi and Louisiana.
NASA estimated an atmospheric velocity of roughly 55,000 mph. As the object fragmented, it released energy equivalent to several tons of TNT and generated strong pressure waves.
The event became even more scientifically valuable when meteorites from the fall were subsequently recovered.
The combination of atmospheric observations, acoustic reports and surviving meteorites makes the Mississippi event one of the best-documented meteor-boom cases in the modern Strange Sounds archive.
Status: CONFIRMED
May 2022 Mystery Booms
MAY 18 · SOUTHERN WESTERN AUSTRALIA
Brilliant Fireball and Explosion-Like Booms Reported Across Western Australia
A bright green-blue fireball crossed the predawn sky over southern Western Australia and was observed across a large geographic area.
Meteor cameras recorded the event, while some witnesses reported loud explosion-like sounds associated with the fireball.
The visual meteor itself is well established. The available evidence also strongly suggests that at least some of the reported booms were produced by its atmospheric shockwave, although the acoustic component was not characterized as thoroughly as in the Pittsburgh, Mississippi or Utah events.
Status: LIKELY
August 2022 Mystery Booms
AUGUST 13 · NORTHERN UTAH / SOUTHERN IDAHO, USA
Mysterious Utah Boom Is Traced to a Meteor Shockwave
A huge boom rattled communities across northern Utah and parts of southern Idaho, prompting immediate speculation about earthquakes, military activity and explosions.
No earthquake capable of producing the disturbance was detected.
Then the evidence began pointing upward.
Ground cameras captured a meteor passing through the atmosphere, while the GOES-17 Geostationary Lightning Mapper detected flashes at the relevant time in an area without thunderstorms.
Together, those observations strongly established that the widely reported boom was produced by an incoming meteoroid and its atmospheric shockwave.
The event is important historically because contemporary reports initially described the booms as unexplained. Later evidence transformed it into one of the year’s clearest resolved mystery-boom cases.
Status: CONFIRMED
October 2022 Mystery Booms
OCTOBER 6 · OUTER BANKS, NORTH CAROLINA, USA
Powerful Seneca Gun Rattles North Carolina’s Outer Banks
A large explosion-like boom shook communities around Kitty Hawk and Kill Devil Hills on North Carolina’s Outer Banks.
Witnesses reported rattling windows, shaking buildings and enough force in some locations to knock objects from walls.
No corresponding earthquake was identified. Military officials also reported no relevant training or aircraft activity that clearly explained the event.
The disturbance belongs to a centuries-old family of unexplained coastal acoustic events commonly called Seneca Guns, sea booms or coastal skyquakes.
North Carolina has one of the best-known histories of these reports in the United States, particularly around the Cape Fear region and Outer Banks.
Status: UNRESOLVED
November 2022 Mystery Booms
NOVEMBER 30 · GRAN CANARIA, CANARY ISLANDS, SPAIN
Gran Canaria Bolide Produces Powerful Shockwave Recorded by Seismic Instruments
Residents across Gran Canaria reported a powerful roar and pressure wave associated with a bright object crossing the sky.
Early speculation suggested that a meteorite might have struck the ocean near the island. Later analysis provided a different interpretation.
Evidence indicated that the object disintegrated in the atmosphere, producing a powerful shockwave rather than a confirmed ocean impact.
The pressure wave generated a characteristic acoustic signal that was recorded by seismic monitoring stations in the Canary Islands.
The case is another excellent demonstration of atmospheric pressure waves coupling into the ground strongly enough to appear on instruments normally associated with earthquakes.
Status: CONFIRMED
What Caused the Mystery Booms of 2022?
| Cause | 2022 examples | Evidence |
|---|---|---|
| Meteors & bolides | Pittsburgh, Mississippi, Western Australia, Utah, Gran Canaria | Satellite detections, meteor cameras, visual observations, infrasound, seismic coupling, recovered meteorites and regional boom reports |
| Coastal skyquakes / Seneca Guns | Outer Banks, North Carolina | Widespread acoustic reports with no corresponding earthquake or confirmed conventional source |
| Unidentified atmospheric or near-surface disturbance | Orcas Island, Washington | Instrumental seismic detection showing propagation consistent with an atmospheric pressure wave rather than an earthquake |
| Unresolved regional boom | South Jersey / Delaware | Widespread witness reports with earthquake and obvious conventional explanations not confirmed |
The strongest pattern in 2022 is unmistakable: meteors and atmospheric bolides produced most of the year’s best-documented mystery booms.
Five of the eight curated events are directly or probably associated with meteoroids entering Earth’s atmosphere.
At the same time, the Orcas Island and Outer Banks cases show why the broader mystery-boom phenomenon cannot simply be reduced to meteors. Some acoustic disturbances remain difficult to identify even when seismic networks and official investigations provide unusually good data.
The Science Behind the Mystery Booms of 2022
How Can a Meteor Sound Like a Huge Explosion?
Meteoroids enter Earth’s atmosphere at hypersonic velocities. They travel much faster than the speed of sound and continuously compress the atmosphere around them.
This generates shockwaves. If the object fragments violently, an additional burst of energy can intensify the pressure disturbance.
When those waves eventually reach the ground, witnesses may hear a single cannon-like bang, multiple explosions, rolling thunder or a prolonged rumble.
Why Does the Boom Arrive After the Fireball?
Light from a meteor reaches observers effectively instantaneously, while sound travels through the lower atmosphere at only about 340 meters per second under typical conditions.
A fireball tens of kilometers high can therefore disappear long before its shockwave reaches the ground.
A delay between the flash and the boom is consequently one of the most useful clues that a bright object produced an atmospheric shockwave.
Can a Meteor Shockwave Be Detected as an Earthquake?
Not exactly — but it can appear on seismic instruments.
A strong pressure wave moving through the atmosphere can strike Earth’s surface and transfer a fraction of its energy into the ground. Seismometers then record this acoustic-to-seismic coupling.
The Gran Canaria event provides an excellent 2022 example.
What Made the Orcas Island Boom Unusual?
Seismic stations recorded the disturbance, but its arrival pattern did not behave like seismic waves spreading outward from an earthquake hypocenter.
Instead, the signal was consistent with an atmospheric or near-surface pressure wave.
This illustrates an important principle: a disturbance recorded by a seismometer is not automatically an earthquake.
What Are Seneca Guns?
Seneca Guns is one of several traditional names for unexplained cannon-like booms reported near coastlines. Similar phenomena have been called sea booms, mistpouffers, Barisal Guns and coastal skyquakes in different parts of the world.
Potential explanations include offshore seismic activity, distant thunder, meteors, military aircraft, wave-generated acoustic processes and atmospheric ducting.
No single explanation accounts for every historical report.
Why Are Coastal Mystery Booms Hard to Locate?
Sound moving over water can travel unusual distances, particularly when atmospheric temperature and wind structures refract acoustic energy back toward the surface.
This can make a distant source sound surprisingly local and can produce reports spread along many kilometers of coastline.
What Is Atmospheric Ducting?
Normally, sound spreads outward and gradually weakens. Temperature inversions and strong vertical wind gradients can instead bend acoustic waves toward Earth’s surface.
This creates an atmospheric sound duct capable of carrying low-frequency noise far beyond its expected range.
Explosions, thunder, sonic booms and other distant acoustic events can therefore sometimes be heard or felt far from their original source.
The Most Important Mystery Boom Events of 2022

A New Year’s Day boom across southwestern Pennsylvania was traced to a meteor airburst detected by satellite and infrasound instruments.
Orcas Island Mystery Boom
An unusually strong unresolved case in which seismic instruments recorded an atmospheric pressure wave without identifying its physical source.
Mississippi Meteor Boom
A daylight fireball generated powerful booms and vibrations before meteorites from the event were recovered on the ground.
Utah Meteor Shockwave
A huge regional boom initially considered mysterious was later tied convincingly to a meteor using ground cameras and satellite observations.

A spectacular atmospheric event generated a powerful pressure wave recorded across the Canary Islands seismic monitoring network.
How the Mystery Booms of 2022 Archive Was Reconstructed
The earlier Strange Sounds archive grouped 2022 through 2025 into a single page because relatively few incidents had initially been retained.
A wider retrospective review revealed enough scientifically useful 2022 events to justify a dedicated annual archive.
The page has therefore been rebuilt using stricter editorial criteria.
- Events are included because the acoustic or pressure-wave phenomenon itself is significant.
- Known industrial explosions and infrastructure accidents are excluded.
- Known military detonations and ordnance explosions are excluded.
- Meteors are retained when meaningful sonic booms, pressure waves or rumblings were documented.
- Later scientific evidence replaces speculation published immediately after an event.
- Instrumental evidence is prioritized over viral claims or isolated social-media reports.
- Events are dated by when they occurred, not by publication date.
- Generic compilation articles redirect to this annual archive rather than becoming separate timeline entries.
- Unresolved events remain explicitly unresolved when evidence does not support a reliable explanation.
What Was Removed From the Old 2022–2025 Mystery Booms Page?
The previous combined archive mixed genuine mystery-boom phenomena with conventional explosions and explosion-risk stories.
Those events have now been separated.
For example, wildfires detonating unexploded World War I munitions are dramatic, but the source of the explosions is known and therefore does not belong in a mystery-boom archive.
Likewise, the July 2022 Hoover Dam incident and the August 2022 Cuban fuel-terminal disaster were identifiable infrastructure or industrial events rather than unexplained acoustic phenomena.
Removing these stories makes the annual archive smaller but substantially more useful.
The goal is not to collect every loud explosion reported during 2022. The goal is to preserve the events that help document and explain the broader mystery-boom, skyquake and atmospheric shockwave phenomenon.
Mystery Booms 2022 — Frequently Asked Questions
What caused the mystery booms of 2022?
Many of the strongest 2022 events were caused by meteors and bolides producing atmospheric shockwaves. Other cases included an unresolved pressure-wave event on Orcas Island, a coastal Seneca Gun on North Carolina’s Outer Banks and an unexplained regional boom around South Jersey and Delaware.
What caused the huge Pittsburgh boom on January 1, 2022?
The boom was caused by a meteoroid entering and disrupting in Earth’s atmosphere. Satellite and infrasound observations detected the event, and NASA estimated an energy release equivalent to roughly 30 tons of TNT.
What caused the Mississippi boom in April 2022?
A fast-moving daylight meteor fragmented over the region, producing atmospheric shockwaves and loud booms across Mississippi and Louisiana. Meteorites from the event were later recovered.
Was the August 2022 Utah boom ever explained?
Yes. Although initially reported as mysterious, camera footage and satellite detections strongly established that a meteor produced the August 13 boom over northern Utah and southern Idaho.
What caused the Orcas Island mystery boom in March 2022?
The exact source remains unresolved. Seismic instruments detected the event, but analysis indicated that the disturbance propagated like an atmospheric pressure wave rather than an earthquake.
What was the Outer Banks Seneca Gun in October 2022?
Residents around Kitty Hawk and Kill Devil Hills reported a powerful cannon-like boom that shook structures. No corresponding earthquake or confirmed conventional source was identified, making it another example of the long-reported coastal Seneca Gun phenomenon.
Did a meteorite hit the ocean near Gran Canaria in November 2022?
A confirmed ocean impact was not established. Later analysis indicated that the object disintegrated in the atmosphere and generated a powerful shockwave recorded by seismic monitoring stations in the Canary Islands.
Can meteor shockwaves shake houses?
Yes. A sufficiently strong atmospheric shockwave can rattle windows, doors and building panels and can even transfer enough energy into the ground to be detected by sensitive seismic instruments.
Does unresolved mean a mystery boom was paranormal?
No. Unresolved means only that available observations are insufficient to identify the source confidently. It does not imply paranormal activity, unknown physics or an extraordinary cause.
Mystery Booms by Year
Report a Mystery Boom
Did you hear or feel a sudden unexplained boom, skyquake or unusual rumbling?
The most useful reports include the exact location, local date and time, duration, direction of the sound, whether a flash or object was visible, whether buildings or windows shook, local weather conditions and whether other witnesses experienced the event.
Video or audio can be especially useful when an exact timestamp is available because it allows the event to be compared with meteor observations, lightning data and seismic records.
