Israeli citizens prefer faster earthquake warnings – even when accuracy is low, research reveals
3. The green circle represents a subset of events that could be considered a potential alert for a magnitude threshold of M≥4.2. The brown circle represents a subset of events that could be considered a potential alert for a threshold of magnitude 4.5. (See the proposed alert approach in the Israel section of NOF and Kurzon (2021) for more information).…
