An Earthquake Early Warning is issued for areas where seismic intensity of 4 or higher is predicted when the expected magnitude of earthquake motion is approximately seismic intensity 4 or higher.
[True / False · Hard]
Answer: False
Explanation
The Rules of the Road, under "2. When an Earthquake Early Warning is Issued," states that an Earthquake Early Warning is issued for areas where seismic intensity of 4 or higher is predicted when the expected magnitude of earthquake motion is approximately seismic intensity 5-lower or higher. The question states "seismic intensity 4 or higher," but the correct threshold is "seismic intensity 5-lower or higher."
