Don't learn about earthquakes from Dwayne 'The Rock' Johnson's new disaster film, San Andreas, kids.

That's the bottom line from American earthquake expert Lucy Jones, who attended the Hollywood premiere on Wednesday and hilariously live-tweeted every inaccurate moment.

While the U.S. Geological Survey seismologist probably lost most people at "subduction zone", she didn't mince her words when she called the action movie "over the top".

"First big safety message - if the shaking is bad enough to damage a dam you won't be able to run," Dr Jones tweeted shortly after posing for a photo with Johnson on the red carpet.

Sorry Dwayne, nothing personal.

Safety was a major concern. The seismologist appeared frustrated as people ran around in the film instead of finding cover as the earthquake hit.

Yes! Drop, cover& hold on. The right thing to do in an earthquake— Dr. Lucy Jones (@DrLucyJones) May 27, 2015

Now people fall trying to run but they run anyway. I guess only the seismologists know Drop Cover Hold On— Dr. Lucy Jones (@DrLucyJones) May 27, 2015

We expect serious damage to 1 in every 16 buildings in a real San Andreas EQ. The movie damage over the top.— Dr. Lucy Jones (@DrLucyJones) May 27, 2015

By the time a giant chasm had opened up in San Francisco and a tsunami was bearing down, Dr Jones couldn't take it anymore and blasted the film for entering "fantasy territory".

She also seemed a little scepital that in the event of an earthquake, people would be rescued by the cute love interest they just met. Though, one can always hope.

The siesmologist did, however, applaud the San Andreas filmmakers for making the heroine of the film an earthquake-savvy woman, which she said was good for emergency training messages.

If only natural disaster experts live-tweeted every Hollywood disaster blockbuster premiere.

The competent young woman knows what to do! And wins over the guys. Advertising for emergency training— Dr. Lucy Jones (@DrLucyJones) May 27, 2015

The human reality of EQs. You are probably going to be rescued by your neighbour- or the cute guy you just met— Dr. Lucy Jones (@DrLucyJones) May 27, 2015

OMG! A chasm? If the fault could open up, there'd be no friction. With no friction, there'd be no earthquake— Dr. Lucy Jones (@DrLucyJones) May 27, 2015

Great emotional message - not knowing if your family is ok is hard. Do you have a family communication plan?— Dr. Lucy Jones (@DrLucyJones) May 27, 2015

Recognizing water draw down as sign of tsunami is good. However tsunami from San Andreas is impossible. Now we are in fantasy territory— Dr. Lucy Jones (@DrLucyJones) May 27, 2015

Competence makes the girl sexy! That's a new message i can applaud!— Dr. Lucy Jones (@DrLucyJones) May 27, 2015

Bottom line: don't learn seismology from #SanAndreas but maybe it will inspire people to take Community Emergency Response Training— Dr. Lucy Jones (@DrLucyJones) May 27, 2015
