It marked Jisoo's first single under her own label since departing from YG Entertainment and Interscope Records as a solo artist in 2023. An electropop song about the excitement of new love, "Earthquake" was written by Jisoo with Jack Brady, Jordan Roman, Sarah Troy and Sara Boe, while it was produced by Blissoo and the Wavys.
"Earthquake" received positive reviews for its catchy quality and upgraded production as compared to her debut single "Flower" (2023). It became Jisoo's first number-one song on the US Billboard World Digital Songs chart and peaked at number 47 on the Billboard Global 200. The song also peaked at number 41 on South Korea's Circle Digital Chart and entered the top ten in Hong Kong, Malaysia, Singapore, Taiwan, and Vietnam. An accompanying music video was directed by Christian Breslauer and uploaded on Jisoo's YouTube simultaneously with the single's release. It shows the singer dealing with an unexpected text message from her lover at work and being interrogated with a lie detector test about her true feelings for him. To promote the song, Jisoo performed at the South Korean music program Inkigayo and on her fanmeet tour Lights, Love, Action! in Asia.
