The Great Los Angeles Earthquake Plot Summary

Read the complete plot summary and ending explained for The Great Los Angeles Earthquake (1990). From turning points to emotional moments, uncover what really happened and why it matters.


The film opens with a small tremor rattling the hills outside Los Angeles, then shifts to a sunny moment at Universal Studios where a teenage girl, Heather Holly Fields Winslow, shares a rush of nerves on a date near the Earthquake Ride. Heather is the daughter of Clare Winslow Joanna Kerns, a USGS seismologist whose days are spent chasing tremors and patterns that could foretell a catastrophe.

Clare and her diligent team, including Jerry Soloway Ed Begley Jr., have been tracking a cluster of unusual seismic activity around Los Angeles. Their data points point toward a sobering possibility: a major earthquake along the San Andreas Fault could unleash havoc on the city, with the potential to reshape lives in a matter of minutes. Clare’s cautious certainty clashes with political and media pressures, especially after a sensational interview with Kevin Conrad Richard Masur—a newsman who twists the moment to sensationalize fear for ratings. The broadcast stirs a political firestorm and strains the marriage between Clare and her husband Steve Winslow Dan Lauria, who worries about the public panic that could follow such warnings.

Across town, Wendell Cates Robert Ginty, a wealthy real estate developer, stands to lose money—and influence—if the city acts on Clare’s warnings. He admires Clare’s intellect but fears the political and financial fallout that could derail his projects. He’s not the only one feeling the heat; city officials, including Mayor Frank Baldwin Charles Siebert, Chad Spaulding Joe Spano of the Office of Emergency Management, and other leaders, wrestle with whether to alert the public or try to maintain calm to prevent panic.

The film also explores Clare’s fragile family life. Her relationship with her teenage daughter Heather is strained, a tension mirrored by Anita Parker Bonnie Bartlett, Clare’s mother, and Laurie Parker Lindsay Frost, Clare’s sister, who has her own romantic entanglements with LAPD officer Matt Alan Autry. As tremors begin to shift toward the Newport-Inglewood fault, the authorities decide to hold a news conference to warn residents, even as many people feel it may already be too late to prepare.

When the long-anticipated quake finally roars to life, it peaks at 8.0 on the magnitude scale and is swiftly followed by a 7.2 aftershock. The devastation cascades through the city, bringing down skyscrapers and collapsing gymnasiums, leaving thousands dead and trapping many survivors in shocking, harrowing moments. Anita Parker is trapped in an elevator with Laurie during a high-rise crisis and, despite a moment of reconciliation, dies when the elevator plummets to the bottom. Sonia Silvana Gallardo loses her son Miguel Jacob Vargas to the wreckage of a school gym during graduation rehearsal, a heartbreak that haunts Clare as she searches for answers and for a way to save others.

Other casualties mount as the city’s skyline bears the brunt of the quake: Wendell Cates falls to his death from a skyscraper window, and Chad Spaulding is electrocuted while trying to escape from a safety bunker beneath City Hall. Amid the wreckage, Kevin Conrad Richard Masur transforms from a cut-throat reporter chasing a sensational story into a more empathetic figure, moved by the scale of the tragedy and the real human cost behind every statistic. Steve Winslow, whom many presume dead after being crushed by debris at an airport, is eventually revealed to have survived, a fragile thread of hope in the chaos.

As the dust settles, the film focuses on the broader political and social fallout. Clare works to keep lines of communication open with officials and the public, navigating fear, blame, and the fragile fabric of a city trying to recover. The story follows her relentless pursuit of family reunification and the healing that must follow a disaster of this magnitude, even as communities pick up the pieces and people reckon with what comes next. The earthquake’s toll—lives lost, families fractured, and reputations tested—serves as a stark reminder of how quickly stability can be upended, and how essential it is to hold onto hope when everything around you seems to collapse.
