Mysterious ‘skyquake’ that shook San Diego may have been caused by plane flying off the coast at 1,100 MPH

  • On Tuesday, a sonic boom sounded over parts of California and Mexico and
  • Loud noise hit residents 17 miles outside of San Diego County
  • Officials aren’t sure what’s causing it, but online flight records may provide the answer
  • Data shows an unidentified plane flies into the area around 8:20 p.m. PST
  • A recorded speed also reveals that it hit 967 knots offshore

A mysterious sonic boom shook parts of California and Mexico Tuesday night, marking the third time since February that residents have experienced an incident many are calling a “skyquake.”

Officials don’t know what caused the loud noise, but flight records showed an unidentified plane traveling at supersonic speeds off the coast of San Diego County around 8:20 p.m. PST — minutes before the quake was heard.

Flight tracking data captured an aircraft hovering at altitudes between 20,000 and 25,000 feet at a recorded speed of 967 knots, or 1,112 mph.

The sonic boom was so loud it startled homes, startled pets and raised concerns about an earthquake among those living within 17 miles of San Diego County.

The phenomenon was reported by residents as far south as Tijuana and as far east as El Cajon in Mexico, The San Diego Union Tribune reports.

In the US, reports surfaced in the San Diego neighborhoods of the Southeast and in the coastal areas, as well as Linda Vista, Clairemont and Tierrasanta.

The previous incident shook the area around 4:55 p.m. PST on March 10, hitting Rancho Bernardo and Chula Vista in California and again in El Cajon.

After Tuesday’s incident, San Diego Mayor Todd Gloria shared an announcement via Twitter that may have been an attempt to enlighten residents, but it seemed to have the opposite effect.

Gloria wrote: ‘Yes, I heard. Now I don’t know what it was. I will share it when I have information. Get vaccinated if you haven’t already.’

A Twitter user, “Politically Stripped,” called the mayor and said San Diego has been hit by mysterious explosions three times and that “nobody has any answers.”

Twitter account SD Sports Curse responded: ‘The vaccines stop the spread of Booms.’

The only clues to the cause of the loud noise were recorded by online flight-tracking websites.

ADS-B Exchange flagged an unidentified plane flying near the shoreline, which appears to be the only clear answer to the mysterious sonic boom, The ride reports.

Rick Kane, a Newport Beach resident, speculated that the unidentified craft was an F-15.

“I suspect an F-15 from the 422nd TES was responsible for these booms. Maybe the Navy was testing a first pod or targeting a radar,” Kane tweeted.

San Diego County is surrounded by a number of naval bases, and tweets shared by “Warship Cam” show that the Nimitz-class carrier USS Carl Vinson was operating in the area the day the bang was heard.

The massive warship left Coronado Naval Base on June 7 and returned on June 9.
