An Earthquake is currently the most unpredictable natural disaster. While meteorologists can track cyclones, hurricanes and tornadoes using satellites and pressure systems, seismologists have no way to predict exactly when a fault will rupture. We can identify “where” (high-risk zones) but never “when” with enough precision for evacuation. ANSWER: (C) Earthquake
Which of the following is an unpredictable natural disaster? (A) Tornado (B) Hurricane (C) Earthquake (D) Cyclone

Weather-related disasters like cyclones provide days or hours of warning through atmospheric changes. Even volcanoes often give signs like gas emissions and small tremors (harmonic tremors) before erupting. Earthquakes, however, happen deep underground without consistent “precursor” signals. Despite decades of research into animal behavior, radon gas and electromagnetic changes, no reliable method exists to predict an earthquake. The “stress” in the crust builds up silently over centuries and releases in seconds. Currently, our only “warning” is Earthquake Early Warning (EEW) systems, which detect the fast P-waves and send an alert seconds before the destructive S-waves arrive.
