Schemes of earthquake shelter location and districting planning in three scenarios.
(SA1), (SB1), and (SC1) are schemes with the minimal shelter area in scenarios SA, SB, and SC respectively; (SA2), (SB2), and (SC2) are schemes with the median shelter area in scenarios SA, SB, and SC respectively; (SA3), (SB3), and (SC3) are schemes with the maximal shelter area in scenarios SA, SB, and SC respectively.
