In reflection seismology, a seismic attribute is a quantity extracted or derived from seismic data that can be analysed in order to enhance information that might be more subtle in a traditional seismic image, leading to a better geological or geophysical interpretation of the data. Examples of seismic attributes can include measured time, amplitude, frequency and attenuation, in addition to combinations of these. Most seismic attributes are , but those that use , such as amplitude versus offset (AVO), must be analysed . They can be measured along a single seismic trace or across multiple traces within a defined window.

| - Un atributo sísmico es una transformación muestra a muestra de datos sísmicos. Los atributos pueden ser calculados tanto a partir de datos sísmicos pre o post (stack o post-stack) como antes o después de realizar . El procedimiento es el mismo en todos estos casos. Se los puede clasificar de muchas formas y varios autores han dado sus propias clasificaciones. (es)
- 地震屬性（英語：seismic attribute）是指從地震數據中经过数学变换而導出的一個量，可以對其進行分析，從而對數據進行更好的地質或地球物理解釋。如反射波的時間、幅度、頻率和衰減等屬性。是從疊加后的地震數據提取，而振幅随偏移距的变化(AVO)，必須在疊加前進行提取。 早期應用的屬性是屬一維屬性例如振幅包络、瞬時相位、瞬時頻率和視極性。聲阻抗。其他常用的屬性包括：相干性、方位角、傾角、瞬時幅度、響應幅度、響應相位、瞬時帶寬、AVO，頻譜分解，平均振幅，平均能量， 均方根幅度，最大振幅，非彈性衰減因子， 曲率等。 (zh)

Most seismic attributes are , but those that use , such as amplitude versus offset (AVO), must be analysed . They can be measured along a single seismic trace or across multiple traces within a defined window. The first attributes developed were related to the 1D complex seismic trace and included: , instantaneous phase, instantaneous frequency, and . Acoustic impedance obtained from seismic inversion can also be considered an attribute and was among the first developed. Other attributes commonly used include: coherence, azimuth, dip, instantaneous amplitude, , , , AVO, and spectral decomposition. A seismic attribute that can indicate the presence or absence of hydrocarbons is known as a direct hydrocarbon indicator. (en)
