Consider the following statements regarding the key characteristics of earthquakes:

  1. Earthquakes strike suddenly, and their exact timing cannot be accurately predicted with current technology.
  2. Regions prone to earthquakes are typically well-known due to distinct geological features and historical seismic activity.
  3. Advanced scientific methods now allow for reliable forecasting of earthquake occurrences within a narrow time frame.

    Aഒന്ന്

    Bഒന്നും മൂന്നും

    Cരണ്ട്

    Dഒന്നും രണ്ടും

    Answer:

    D. ഒന്നും രണ്ടും

    Read Explanation:

    Earthquake prediction, in terms of forecasting the exact location, time, and magnitude of future earthquakes, remains one of the greatest challenges in earth science. Despite extensive research, the complex and chaotic nature of crustal movements makes precise forecasting impossible with current technology. However, scientists can identify earthquake-prone regions, known as seismic zones, by studying plate tectonics, geological fault lines, and historical earthquake records. These risk zones are often located along plate boundaries, where the majority of the world's seismic activity occurs, allowing for preparedness measures like building codes and early warning systems for the initial tremors, though not for predicting the event itself.
