本文提供了针对不同地震烈度（Modified Mercalli Intensity, MMI）下的人口暴露评估数据，包括感知震感、潜在结构损害等信息，并列举了特定城市的人口暴露情况。需要注意的是，这些数据为初步估计，随着更多信息的收集将进行更新。

Estimated Population Exposed to Earthquake Shaking

Est. Modified Mercalli Intensity	Est. Population Exposure (k = x1000)	Perceived Shaking	Potential Structure Damage
Est. Modified Mercalli Intensity	Est. Population Exposure (k = x1000)	Perceived Shaking	Resistant	Vulnerable
X	21k	Extreme	V. Heavy	V. Heavy
IX	86k	Violent	Heavy	V. Heavy
VIII	1,072k	Severe	Moderate/Heavy	Heavy
VII	3,567k	Very Strong	Moderate	Moderate/Heavy
VI	10,123k	Strong	Light	Moderate
V	42,892k*	Moderate	V. Light	Light
IV	8,827k*	Light	None	None
II-III	--*	Weak	None	None
I	--*	Not Felt	None	None

*Estimated exposure only includes population within the map area.

Users should consider the preliminary nature of this information and check for updates as additional data becomes available. Population exposure estimates are NOT a direct estimate of earthquake damage; comparable shaking will result in significantly lower losses in regions with well built structures than in regions with vulnerable structures.
