Haiti-based digital media outlet HaitiLibre has expanded its popular twice-weekly general knowledge quiz segment, “Did You Know?”, with 30 brand-new interactive games added to its Quiz.HaitiLibre platform as of August 1, 2026. The monthly expansion brings the total number of available quizzes to 210, with new content added on a consistent monthly basis to engage curious learners of all backgrounds.\n\nIn the 47th installment of the “Did You Know?” series, the platform clarified a widespread terminology mix-up between two often-confused coastal natural phenomena: tidal waves and tsunamis. Many people incorrectly use the term “tidal wave” to describe tsunamis, the powerful destructive waves triggered exclusively by underground geological activity such as underwater earthquakes, volcanic eruptions, or seabed collapses. In reality, a true tidal wave — also called a storm surge — is an extreme weather-driven event entirely separate from geological activity.\n\nTidal waves form during intense maritime storms or tropical cyclones, when a combination of extremely low atmospheric pressure and strong gale-force winds pushes ocean water far above normal levels, driving the surge inland onto low-lying coastal territories. The event causes a rapid, temporary inundation of coastal land that often overwhelms protective seawalls and dykes. The destructive potential of a tidal wave increases dramatically when it coincides with an astronomical high tide: repeated wave impacts can breach coastal flood defenses, leading to severe saltwater flooding that destroys residential structures and leaves permanent salt contamination in coastal farmland.\n\nThe Quiz.HaitiLibre platform is designed to be accessible to all audiences, with free access that does not require user registration, three adjustable difficulty levels (easy, intermediate, and hard) for every quiz, and full support for both French and English languages. The platform covers a wide range of topics, from local Haitian current affairs and culture to global general knowledge, with an expert-level section for users seeking more challenging content. After completing each quiz, users can leave feedback via a comment form to help improve the platform, and are encouraged to share the resource with family and friends to foster collective learning. Visitors can access the full collection of quizzes, including all past installments of the “Did You Know?” series, at the platform’s official English website: https://quiz.haitilibre.com/en.
