Key facts — Mystery Booms 2019
- Meteors produced several of the year’s strongest booms. Major cases included Viñales in Cuba, White Springs in Florida, southwest Missouri, central New York and the spectacular November fireball over Missouri.
- Not all sky-shaking blasts came from the atmosphere. Shallow earthquakes produced audible booms in North Carolina and beneath Lake Erie near Cleveland.
- Extreme cold generated explosive sounds around Chicago. The January polar vortex produced widespread reports consistent with cryoseisms, or frost quakes.
- A massive December boom over southern England was conclusively identified as a sonic boom from RAF Typhoon fighter jets responding to an aircraft communications emergency.
- Several significant disturbances remained unresolved, including recurring booms around Tucson, coastal North Carolina, Block Island, Cleveland’s Slavic Village and Grand Island, New York.
What Were the Mystery Booms of 2019?
A mystery boom is a sudden explosion-like sound, pressure wave or rumbling disturbance whose source is not immediately apparent.
It is a description of an observation — not a single scientific phenomenon.
A meteoroid traveling through the atmosphere can generate a sonic shockwave. A shallow earthquake can sound like an underground explosion. Frozen soil can fracture violently during a cryoseism. Supersonic aircraft can produce pressure waves capable of rattling windows across large regions.
Other events remain unresolved simply because the disturbance was too brief, too poorly instrumented or too distant from sensors to identify retrospectively.

How the 2019 Mystery Booms Are Classified
Instrumental, official or strong documentary evidence identifies the physical source.
One explanation is strongly supported, although some uncertainty remains.
The event is credibly documented, but available evidence does not establish the source.
Surviving reports are too incomplete or contradictory for a reliable interpretation.
Unresolved does not mean paranormal. It means the available evidence is insufficient to identify the source confidently.
January 2019 Mystery Booms
JANUARY 30–31 · CHICAGO & MIDWEST, USA
Polar Vortex Triggers Explosive Frost Quakes Around Chicago
During the extreme cold outbreak of late January 2019, residents around Chicago and other parts of the Midwest reported sudden nighttime bangs powerful enough to wake people and shake homes.
The sounds were widely attributed to cryoseisms — commonly called frost quakes.
Cryoseisms can occur when saturated soil rapidly freezes and expands. Stress builds in frozen ground until it fractures suddenly, producing a sharp explosive crack and localized vibration.
Unlike tectonic earthquakes, frost quakes are generally shallow and extremely localized.

February 2019 Mystery Booms
FEBRUARY 1 · VIÑALES, CUBA
Daytime Bolide Explodes Over Cuba and Drops Meteorites Near Viñales
A spectacular daylight fireball crossed western Cuba before producing powerful sonic booms heard around Viñales.
Witnesses reported a brilliant object fragmenting in the sky followed by loud explosion-like sounds.
Fragments subsequently reached the ground around Viñales, turning the event into one of the best scientifically documented meteor-boom cases of 2019.
The recovered meteorites were classified as an L6 ordinary chondrite.
Status: CONFIRMED

FEBRUARY–MARCH · TUCSON, ARIZONA, USA
Recurring Mystery Booms Shake Tucson
Southern Arizona experienced a series of powerful unexplained booms during February and March 2019.
Residents described windows rattling, houses shaking and sudden explosion-like noises across the Tucson area.
Some events were captured by security cameras, while University of Arizona seismic equipment recorded ground vibration associated with at least some of the disturbances.
A particularly strong March event reportedly continued for nearly 30 seconds, but available seismic evidence did not support an ordinary local earthquake as the explanation.
Military activity, quarry blasting and atmospheric sources were discussed, but no single cause was established for the series.
Status: UNRESOLVED

March 2019 Mystery Booms
MARCH · RHODE ISLAND, USA
Mystery Boom Heard Across Block Island and Coastal Rhode Island
Residents around Block Island reported a powerful unexplained boom that was also heard across parts of coastal Rhode Island.
The event generated speculation about aircraft, offshore activity and atmospheric sound propagation, but no conclusive source emerged.
Its broad coastal footprint makes it a good modern example of the class of events historically described as coastal skyquakes.
Status: UNRESOLVED
MARCH 6 · OUTER BANKS, NORTH CAROLINA, USA
Powerful Seneca Gun-Like Boom Rattles the North Carolina Coast
A large explosion-like boom shook homes across portions of coastal North Carolina.
Residents reported rattling windows, moving pictures and doors being jolted by the disturbance.
The U.S. Geological Survey checked its seismic network and found no earthquake capable of explaining the event.
The incident drew comparisons with the long history of unexplained coastal booms known locally as Seneca Guns.
Status: UNRESOLVED

MARCH 26 · NORTH CAROLINA, USA
Two Small North Carolina Earthquakes Produce Audible Booms
Two small earthquakes struck North Carolina on March 26 and were accompanied by reports of loud explosion-like sounds and shaking.
The events measured approximately M2.6 and M2.5.
Small shallow earthquakes can produce surprisingly loud cracking or booming noises when high-frequency seismic energy reaches the surface close to observers.
Status: CONFIRMED

April 2019 Mystery Booms
APRIL 4 · FLORIDA, USA
Fragmenting Fireball Over Florida Produces Sonic Reports and Radar Echoes
A bright fireball crossed the southeastern United States and was seen from Florida, Georgia, Alabama and South Carolina.
The American Meteor Society received dozens of eyewitness reports, including reports of sonic sounds associated with the event.
Weather radar also detected signatures interpreted as falling meteorite material near White Springs, Florida.
NASA classified the event as a probable meteorite fall, although meteorites had not been confirmed recovered at the time of its report.
Status: CONFIRMED ATMOSPHERIC EVENT
Reference:NASA — White Springs, Florida fireball
APRIL 14 · GRAND’ANSE, HAITI
Powerful Mystery Explosion Heard Across Haiti’s Grand’Anse Department
Residents across much of Haiti’s Grand’Anse department reported an enormous explosion-like sound.
Authorities found no evidence of a significant earthquake or volcanic event capable of explaining the disturbance.
Haiti’s Bureau of Mines and Energy discussed an atmospheric meteor explosion as one possible explanation, but the hypothesis was never established conclusively.
Status: UNRESOLVED
May 2019 Mystery Booms
MAY · CLEVELAND, OHIO, USA
Flashes of Light and Repeated Booms Baffle Cleveland’s Slavic Village
Residents in Cleveland’s Slavic Village neighborhood reported repeated bright flashes accompanied by explosion-like booms strong enough to shake homes.
Some of the incidents were captured on security cameras.
Residents contacted police and local officials, but contemporary reporting did not establish a definitive source.
Status: UNRESOLVED

June 2019 Mystery Booms
JUNE 10 · OHIO, USA
Magnitude 4.0 Earthquake Beneath Lake Erie Shakes Greater Cleveland
A magnitude-4.0 earthquake struck beneath Lake Erie near northeastern Ohio and was felt across the Greater Cleveland region.
Residents reported sudden shaking and explosion-like sounds as seismic waves reached populated areas.
Unlike many apparent mystery booms, this event had a clear instrumental source and provided another example of how earthquakes can initially be mistaken for explosions or atmospheric disturbances.
Status: CONFIRMED

2019 · GRAND ISLAND, NEW YORK, USA
Recurring Explosion-Like Booms Trouble Grand Island Residents
Residents of Grand Island reported repeated explosive sounds during 2019, some strong enough to rattle windows and houses.
The phenomenon persisted long enough to attract the attention of town officials, police and engineers.
Possible explanations were discussed, but by the end of the year officials still had not identified a single source capable of explaining the recurring reports.
Status: UNRESOLVED

August 2019 Mystery Booms
AUGUST 11 · MISSOURI, USA
Meteor Lights Up the Ozarks and Produces a House-Shaking Boom
Residents across southwestern Missouri and the Ozarks reported a bright meteor followed by a loud boom and shaking.
The visual observations and delayed acoustic reports strongly supported an atmospheric shockwave from the incoming meteoroid.
Status: LIKELY

September 2019 Mystery Booms
SEPTEMBER 2 · CENTRAL NEW YORK, USA
Bright Fireball and Loud Boom Shake Central New York
Residents across central New York reported a powerful explosion-like sound and shaking while witnesses also observed a bright object crossing the sky.
Fireball reports submitted at approximately the same time supported the interpretation that a meteor-generated atmospheric shockwave produced the boom.
Status: LIKELY

November 2019 Mystery Booms
NOVEMBER 2 · WICHITA, KANSAS, USA
Citywide Boom Rattles Wichita as Fireball Reports Arrive Across the Region
Residents across Wichita and surrounding communities reported a powerful boom accompanied by vibration.
Police found no major explosion, McConnell Air Force Base did not identify military activity responsible for the disturbance, and no significant earthquake corresponded with the reports.
At approximately the same time, multiple observers across Kansas, Missouri and Oklahoma reported a fireball.
The timing makes an atmospheric meteor shockwave a plausible explanation, although the connection was not conclusively demonstrated.
Status: LIKELY
Reference: KWCH — Wichita mystery boom
NOVEMBER 11 · MISSOURI, USA
Spectacular St. Louis Fireball Produces Boom Across the Midwest
A brilliant meteor streaked across the Midwest during the evening of November 11 and was recorded by numerous cameras around Missouri and neighboring states.
Hundreds of witnesses reported the fireball, while residents around the St. Louis area also described a loud explosion-like boom.
NASA reconstructed the fireball’s trajectory using eyewitness reports and video observations.
The combination of visual evidence, timing and acoustic reports makes this one of 2019’s clearest examples of a meteor-generated sonic shockwave.
Status: CONFIRMED

December 2019 Mystery Booms
DECEMBER 1 · LONDON & HERTFORDSHIRE, UK
Massive Overnight Boom Across Southern England Traced to RAF Typhoons
A huge explosion-like boom woke residents across London, Hertfordshire, Essex and neighboring parts of southern England during the early hours of December 1.
Some residents reported shaking homes and windows.
The source was rapidly identified: Royal Air Force Typhoon fighter jets had been scrambled to intercept a civilian aircraft that had temporarily lost communications with air traffic control.
The aircraft were authorized to fly supersonically, producing the widespread sonic boom.
The event is an excellent comparison case because an enormous regional “mystery explosion” was conclusively explained within hours by a conventional atmospheric shockwave.
Status: CONFIRMED

What Caused the Mystery Booms of 2019?
| Cause | Major 2019 examples | Evidence |
|---|---|---|
| Meteors & bolides | Viñales, White Springs, southwest Missouri, central New York, Wichita, St. Louis | Fireball observations, video, radar, sonic-boom reports and meteorite recovery |
| Earthquakes | North Carolina, Lake Erie / Cleveland | Instrumentally detected earthquakes corresponding with felt and acoustic reports |
| Cryoseisms | Chicago / Midwest | Extreme cold, frozen saturated ground and localized explosive cracking |
| Supersonic aircraft | London & Hertfordshire | RAF confirmation of Typhoon aircraft operating supersonically |
| Unresolved regional disturbances | Tucson, Block Island, Outer Banks, Grand’Anse, Slavic Village, Grand Island | Multiple credible witness reports without sufficient evidence to identify a source confidently |
The 2019 archive shows why the phrase “mystery boom” should never be treated as a diagnosis.
Nearly identical descriptions — a bang, shaking windows and a brief pressure sensation — were produced by meteors, earthquakes, frozen ground and supersonic aircraft.
Other cases remain unresolved not because they necessarily require exotic explanations, but because the available observations were insufficient to reconstruct the source.
The Science Behind the Mystery Booms of 2019
Why Do Meteors Produce Sonic Booms?
Meteoroids typically enter Earth’s atmosphere at velocities far above the speed of sound.
Air is compressed violently around the object and its expanding wake, generating shockwaves that travel away from the atmospheric trajectory.
When those pressure waves reach the ground, witnesses may hear a sharp crack, a double boom or a prolonged rolling rumble.
Why Can the Boom Arrive Minutes After the Fireball?
Light reaches observers effectively instantaneously on human timescales, while sound travels through the atmosphere at only a few hundred meters per second.
A fireball tens of kilometers above Earth may therefore disappear long before its shockwave arrives.
A delay of tens of seconds or several minutes can be completely normal.
Can Meteor Shockwaves Shake Buildings?
Yes.
Strong pressure waves can vibrate windows, walls, roofs and doors and may even transfer enough energy into the ground to register on sensitive seismometers.
This can make an atmospheric event feel deceptively similar to an earthquake.
Why Can Small Earthquakes Sound Like Explosions?
Small shallow earthquakes can produce high-frequency seismic energy very close to populated areas.
Instead of a long rolling motion, people may perceive a sudden crack, bang or underground thump.
That effect is particularly noticeable when the earthquake is shallow and close to the observer.
What Is a Frost Quake?
A cryoseism, commonly called a frost quake, can occur when water-saturated soil freezes rapidly.
As freezing water expands, stress accumulates in the frozen ground until the material fractures suddenly.
The resulting sound can resemble a gunshot, explosion or small earthquake.
What Are Seneca Guns and Coastal Skyquakes?
For centuries, people living near certain coastlines have reported powerful unexplained booms with no obvious storm, explosion or earthquake.
In the Carolinas these events are often called Seneca Guns.
Proposed explanations include distant military sonic booms, meteors, offshore seismic activity, surf-related acoustics and unusual atmospheric sound propagation.
Some individual events can be explained, while others remain unresolved.
How Can Atmospheric Conditions Carry Booms Long Distances?
Temperature inversions and strong wind gradients can bend sound waves back toward Earth’s surface.
This process, known as atmospheric ducting, can allow explosion sounds, aircraft noise and other low-frequency disturbances to travel much farther than people expect.
As a result, the source of a boom may be tens or even hundreds of kilometers from the observer.
The Most Important Mystery Boom Events of 2019
Several cases stand out because they provide unusually strong scientific evidence or illustrate a particularly important class of mystery-boom phenomenon.
A daylight bolide, sonic booms and recovered meteorites make the Cuban event one of the year’s best-confirmed meteor-shockwave cases.
Repeated house-shaking disturbances and seismic detections make the Tucson series one of 2019’s strongest genuinely unresolved boom cases.
A strong coastal boom with no corresponding earthquake provides a modern example of the long-running Seneca Guns phenomenon.
Videos, widespread observations and NASA trajectory analysis make the November Missouri fireball one of the year’s clearest meteor-boom events.
The M4.0 event shows how genuine seismic shaking can initially be experienced as an unexplained explosion-like boom.
The December UK event shows how an enormous regional mystery boom can be completely explained by a confirmed supersonic aircraft shockwave.
How the Mystery Booms of 2019 Archive Was Reconstructed
The original Strange Sounds 2019 archive was assembled from live reports and included numerous local stories, monthly compilations and several events from 2018.
This reconstructed version uses a stricter retrospective standard.
- Only the most important or scientifically useful 2019 cases are retained.
- All 2018 events have been moved to the dedicated 2018 archive.
- Events are organized by when they occurred, not when an article about them was published.
- Routine military noise advisories are excluded.
- Known refinery, electrical, ammunition-depot and industrial explosions are excluded.
- Ordinary aircraft accidents and transportation incidents are excluded.
- Fireballs are included only when there is meaningful evidence of sound, pressure waves or shaking.
- Generic monthly boom compilations redirect to this archive rather than appearing as separate events.
- Later explanations supersede early speculation.
- Meteorite claims are used only when surviving material has actually been documented.
- Unresolved cases remain unresolved when the evidence does not support a specific explanation.
Some legacy Strange Sounds URLs therefore redirect to this annual archive even though the original event is not represented by a separate visible timeline entry.
That is intentional: redirect preservation and editorial importance are different decisions.
What Was Removed From the Original 2019 Mystery Booms Archive?
The rebuilt archive deliberately excludes numerous low-value or clearly explained incidents.
Removed material includes known electrical explosions, refinery explosions, ammunition-depot explosions, building fires, generic boom compilations and minor isolated neighborhood reports.
The old archive also contained several 2018 boom compilations. Those now belong exclusively in the Mystery Booms of 2018
archive.
A story originally published during 2019 is also not automatically a 2019 event. For example, archived material describing the Indianapolis mystery booms of January 2013 belongs with Mystery Booms of 2013.
This chronological cleanup makes the yearly archives substantially more useful as historical references.
Mystery Booms 2019 — Frequently Asked Questions
What caused the mystery booms of 2019?
There was no single cause. Major 2019 cases were linked to meteor shockwaves, earthquakes, cryoseisms and supersonic aircraft, while several regional disturbances remained unresolved.
What was the biggest meteor boom of 2019?
Several were significant. The Viñales event in Cuba produced sonic booms and recovered meteorites, while the November St. Louis fireball was widely observed, recorded on video and reconstructed using NASA data.
Did a meteor explode over Cuba in 2019?
Yes. A bright daylight bolide crossed western Cuba on February 1, 2019 and produced sonic booms. Meteorites were subsequently recovered around Viñales and classified as L6 ordinary chondrites.
What caused the Chicago booms during the 2019 polar vortex?
Many were attributed to cryoseisms, commonly called frost quakes. Rapid freezing of water-saturated ground can build stress until frozen soil or rock fractures suddenly and produces an explosive sound.
Were the Tucson mystery booms of 2019 ever explained?
No single explanation was established for the recurring Tucson disturbances documented here. Some produced measurable ground vibration, but available evidence did not identify an ordinary earthquake as the source.
What caused the December 2019 sonic boom over London?
RAF Typhoon fighter jets were authorized to fly supersonically while intercepting a civilian aircraft that had temporarily lost communications. The resulting sonic boom was heard across a large part of southern England.
Can small earthquakes produce loud booms?
Yes. Small shallow earthquakes can generate high-frequency seismic energy that people close to the source perceive as a crack, bang or explosion-like sound.
What are Seneca Guns?
Seneca Guns are unexplained explosion-like sounds historically reported along parts of the eastern United States, especially coastal North Carolina. Proposed explanations include atmospheric sound propagation, meteors, military sonic booms and offshore seismic or acoustic sources.
Does unresolved mean a mystery boom was paranormal?
No. Unresolved simply means that the surviving evidence is insufficient to identify the physical source confidently. It does not imply paranormal activity or unknown physics.
