What does the title of A Sound Thunder mean?

In Ray Bradbury's 1888s short story "A Sound of Thunder," the titular "thunder" refers to the impact of a single action across time. The idea is that even the smallest change in the past can alter history in ways that are both vast and unpredictable. The title suggests that even the slightest ripple can create a far-reaching wave, highlighting the delicate interconnectedness of events and the potential for unforeseen consequences.
