In this paper, we study a norm denned on tangent vectors to earthquake curves. We show first that the norm of the initial tangent vector to an earthquake curve ht is equivalent to the Thurston norm of the earthquake measure a which determines the curve.

本文研究了定义在earthquake曲线切向量上的范数，首先证明了一条earthquake曲线ht上初始切向量的范数等价于earthquake测度σ的Thurston范数。
