Best practice
When describing vulnerabilities, be specific about what someone or something is "weak to". Instead of simply stating "the structure is weak", clarify "the structure is weak to seismic activity".
Common error
Avoid using "weak to" in contexts where "susceptible to" or "vulnerable to" might be more appropriate. "Weak to" often implies a direct, immediate impact, whereas the other phrases can suggest a longer-term or indirect vulnerability.
