The answer is yes. Brontophobia, also known as astraphobia, is less common than claustrophobia. Brontophobia is an extreme fear of thunder and lightning, whereas claustrophobia is a fear of confined spaces. Both are specific phobias, and more specifically, both are situational phobias.
Brontophobia has a prevalence rate of 2%, whereas claustrophobia has a prevalence of 4% (Fredrikson et al., 1996). Thus, claustrophobia is more common than brontophobia.
