In 2015 the band reformed with new vocalist Kate Jacobi and later guitarist Andy Pohl and has remained active since, touring and appearing on a variety of festivals.
Davi met McRory in late 1997, when she joined Headboard on vocals and had known Sparks from hanging out together at The Phoenix Theater in Petaluma.
Keyboardist Oobliette Sparks would leave the group the following year in 2001, and not being able to replace her, the band would continue without keyboards.
The title song from their first CD release, The Invasion from Within!, was used in Atlus USA's translation of the Nippon Ichi Software strategy RPG Disgaea: Hour of Darkness.
Atlus also used the song Russian Roulette from the band's first full-length album The Ultimate Escape in their collaboration with Spumco animation studios, a cartoon skateboarding game called Go!
Controversy surrounded the split with founding member Davi, long cited as being one of the main songwriters for the band.
In late 2005, after years of touring and numerous line-up changes Tsunami Bomb officially broke up, citing their problems with the "business end of the music industry".
On January 17, 2009, Tsunami Bomb performed a reunion show in their hometown of Petaluma at the Phoenix Theater as a benefit for their friend Liz Beidelman the drummer for the band Luckie Strike who was fighting brain cancer.
In 2015, original members Oobliette, Davi, Brian Plink and Gabriel Lindeman reunited Tsunami Bomb along with Kate Jacobi, who would replace Emily Whitehurst on vocals.
Chris LaForge passed away unexpectedly on May 29, 2017, and the band was deeply affected by his loss, with members posting tributes to his memory on their website and social media pages.
On July 13, 2017, the band began a short Northeast US trip with three shows in Philadelphia, Pennsylvania; Long Branch, New Jersey; and Brooklyn, New York.
At Kung Fu Necktie, in Philly, the band debuted new guitarist Andy Pohl, as well as two never-heard-before songs "Tidal Wave Explosive Device" and "Lullaby for the End of the World" that were intended for a new album.
The two tracks "Lullaby For The End Of The World" and "Naysayers" were released to the public as a digital single on October 5, 2018, and were samples from their upcoming album.
[7] Tsunami Bomb would continue headlining concerts around the United States rebuilding their following, performing short runs of shows rather than the grueling tour schedule they were once known for.
On November 8, 2020 Cleopatra Records released a two song digital single featuring a cover of Hall & Oates track "Out Of Touch" for an upcoming Yacht Rock compilation.
The second song was the cover of "Dead Man's Party" by Oingo Boingo that originally appeared on the Punk Rock Halloween 2: Louder, Faster, & Scarier in 2019.
[17] The music news website Punknews.org streamed Tsunami Bomb's cover of the Fugazi track "Walken's Syndrome" on August 6, 2021.
We chose "Walken's Syndrome" because it's got a lot of energy, and a bit of that dark vibe to it that we felt would compliment [sic] our style and would allow us to pay tribute to them in a way that made the most sense.
"[18] On April 7, 2022, bassist Dominic Davi suffered a stroke and had to be airlifted to nearby hospital in the San Francisco Bay Area.
In the band's own announcement, they indicated they expected Davi to be able to perform, and was continuing to make positive progress but they would keep everyone updated on his condition.
