Summary
Eruption is the result of a unique collaboration between two genre masters, Michael Crichton and James Patterson. The novel centers on the power of nature and human ambition on Hawaii’s Big Island. Dr. John "Mac" MacGregor, head of the Hawaiian Volcano Observatory, confronts the threat of Mauna Loa's possible eruption. Military operations with hidden agendas complicate the situation. Mac deals with challenges as a covert strategy develops beneath the volcanic landscape. Combining Crichton’s scientific detail with Patterson’s suspenseful storytelling, Eruption was released in 2024, nearly 16 years after Crichton’s death, in what was hailed as “a seismic publishing event” (Associated Press).
Plot
Set on Hawaii's Big Island in the present day, Eruption begins with biologist Rachel Sherrill at the Hilo Botanical Gardens. She detects changes in the banyan trees, indicating potential environmental danger. Volcanologist Dr. John "Mac" MacGregor observes increased volcanic activity beneath Mauna Loa. Initially, he reassures the public. However, Mac discovers a hidden threat. The US military has stored toxic chemical weapons, particularly Agent Black, within Mauna Loa. Their release poses a catastrophic risk. Mac and the military, led by Colonel Briggs, work together to address the crisis.
Mac's mission involves a team of scientists attempting to divert lava away from these hazardous sites. Demolition expert Rebecca Cruz uses controlled explosions to prevent disaster. Meanwhile, celebrity volcanologists Oliver and Leah Cutler, backed by billionaire J.P. Brett, complicate matters. Their media presence intensifies public alarm. Brett’s focus on sensationalism contrasts with Mac and General Rivers’s measured crisis response.
The leaking of Agent Black disrupts the ecosystem and spreads chaos among soldiers and locals under martial law. During the turmoil, a helicopter crashes, killing Brett and the Cutlers. In the climax, Mac and Rebecca use aerial bombardment to redirect the lava. As hope diminishes, a cooled lava formation creates a barrier, illustrating nature's unpredictability as a central theme. After containing the threat, the military begins relocating the hazardous waste. Mac decides to move to Houston with Rebecca for academic pursuits, reflecting a personal resolution amid the chaos. Meanwhile, the existence of the Ice Tube remains a secret, keeping the world unaware of the narrowly avoided catastrophe.
Characters

Setting
Eruption takes place on Hawaii's Big Island, highlighting its beauty and danger. The depiction of volcanoes such as Mauna Loa provides both a scenic backdrop and a central conflict, reflecting nature's unpredictability. Biologist Rachel Sherrill finds blackened banyan trees early in the story. This foreshadows the threat of volcanic activity and underscores Hawaii's balance between natural beauty and potential disaster. Crichton’s connection to Hawaii influences the storyline, infusing it with authenticity.
Themes
Volcanology: Volcanic events form the scientific core of Eruption as well as its drama. Interweaving real-world research with speculative elements, the novel highlights volcanic eruptions as both a scientific puzzle and a thriller-worthy threat.
Biologic threat: Eruption introduces Agent Black, a fictional chemical agent reminiscent of defoliants like Agent Orange. Originally for military use, it spreads uncontrollably, destroying plant ecosystems and suggesting possible environmental devastation.
Genetic dangers: Eruption addresses genetic manipulation, focusing on a mishap with insecticides. This highlights the risks of altering plant genomes, showing that such actions can lead to unforeseen consequences.
Technology and its limits: Eruption explores innovative military technology and humanity's efforts to control natural forces. This theme adds tension, framing technological progress against nature’s unpredictability.
Quick facts
Eruption is a novel written by Michael Crichton and James Patterson, completed posthumously by Patterson after Crichton's death.
Michael Crichton began drafting the novel years before his death in 2008, sparked by his intense personal interest and extensive research on volcanoes.
After Crichton’s untimely passing, his notes and the partial manuscript were discovered by his widow, Sherri.
Sherri Crichton spent more than a decade searching for a collaborator to complete Eruption, finally choosing James Patterson.
The novel involves a volcanic eruption of Mauna Loa on Hawaii's Big Island, a potential global ecological disaster due to a hidden stockpile of toxic chemical waste.
Eruption blends Crichton's signature scientific depth with Patterson's talent for fast-paced thrillers.
Patterson engaged external researchers to help interpret Crichton's detailed scientific and volcanic research notes.
The characters include experts such as a volcanologist, a conservation biologist, a demolition expert, and a sensationalist media figure.
Eruption weaves disaster fiction, military secrecy, and scientific detail into a cohesive narrative with strong ecological themes.
The story involves attempts to redirect lava flow with explosives to prevent catastrophic contamination by toxic chemicals.
Eruption was widely praised by critics, described by TIME as “an epic thriller … a cinematic story rooted in science and infused with plenty of heart” and the Washington Post as the “ultimate literary mashup.”
Sony Pictures secured the rights to adapt Eruption for the big screen.
The audiobook of Eruption is performed by award-winning narrator Scott Brick, who won raves from listeners for not only capturing the novel’s tension but also for accurately pronouncing Hawaiian words.
Film adaptation
Sony Pictures acquired the film rights to Eruption, opening Hollywood discussions about a blockbuster. Writers Kaz and Ryan Firpo have been signed to write the screenplay but, as of July 2025, no director is attached to the project. Reports suggest Steven Spielberg might collaborate, as he successfully adapted Jurassic Park.
About the authors
Michael Crichton, a Harvard-trained physician, gained fame for integrating science with storytelling. His groundbreaking novels, including Jurassic Park, The Andromeda Strain, The Great Train Robbery, Prey, Sphere, and Congo, have sold over 250 million copies worldwide. In addition to his novels, he directed the movie Westworld and created the TV series ER.
James Patterson is one of the most popular and prolific storytellers of our time. He is the creator of unforgettable characters and series, including Alex Cross, the Women’s Murder Club, Jane Smith, and Maximum Ride, and of breathtaking true stories about the Kennedys, John Lennon, and Tiger Woods, as well as military heroes, police officers, and ER nurses. He has coauthored #1 bestselling novels with Bill Clinton, Dolly Parton, and Michael Crichton. His works have sold over 400 million copies globally and won him honor from an Edgar Award to the National Humanities Medal.
After Crichton’s death in 2008, Sherri Crichton discovered her late husband's copious notes and partial manuscript focused on a volcanic disaster. Determined to realize his vision, she began to search for an author to complete the work. After more than a decade, she chose Patterson for the project and entrusted him with honoring her husband’s legacy. Along with scouring the research Crichton had compiled to maintain the scientific accuracy, Patterson studied the narrative style typical of Crichton's work. Working closely with Sherri, James Patterson completed Michael Crichton’s manuscript. The result is Eruption, a scientific thriller converging the talents of two outstanding authors.
