Tsunami evacuation at Horikiri district in Tahara city was focused on since there would be hit by a forthcoming Nankai trough earthquake with seismic intensity of 7 at maximum and also be inundated with 2m depth within 18 minutes after the earthquake. In addition, this district is located in low flatland so that evacuation situation is extremely severe. To accomplish safer situation, in 2018, the municipality has built artificial evacuation mound near residential area in low flatland.
