Which risk increases when a coastal city's earthquake early warning system depends exclusively on shallow crustal seismic sensors?

💡 Explanation

Tsunami warning latency increases because subduction zone earthquakes originating offshore transmit energy efficiently through deeper, farther sensors using pressure waves. This wave propagation is quicker than the shallow crustal P-waves near the epicenter, therefore deep sensor information offers early warning, providing increased lead-time rather than relying solely on slower-arriving surface readings.
