‘Disquiet’ means to make someone uneasy. Example:  “I was disquieted by the thunder outside.”

‘Disturb’ has a stronger meaning. Example:  “Seeing him yell at his child was disturbing to me.”

‘Disturb’ can also mean to break someone’s concentration. Example:  “Please don’t disturb me while I’m studying.”

DISTURB implies interference with one's mental processes caused by worry, perplexity, or interruption.  
// the discrepancy in accounts disturbed me //

DISQUIET suggests loss of sense of security or peace of mind.
