How does the author use symbolism in the story, UFO in Kushiro?

The author uses the earthquake in Kobe to represent the turmoil and misfortune in Komura's life. Many of the unfortunate events in Komura's life, such as his divorce and his inability to pursue a sexual relationship with Shimao, are heavily related to the earthquake. For example, Komura's wife leaves after being captivated by news coverage of the earthquake, and Komura's failures with Shimao are attributed to his incessant thoughts about the earthquake.
