本章的目的是了解火山重力测量的一些发展和新趋势。首先，我们将回顾地球物理学这一子领域内的研究工作的目标，讨论其使用的数据和方法，并概述其争取的成果。然后，我们将把注意力转向创新方法可能推动该研究领域发展的三个领域。第一个与地形表面的垂直变形（高程变化）和观测到的重力变化之间的耦合有关，换句话说，就是从观测到的重力变化中去除变形引起的重力信号，以获得由火山信号引起的净重力变化。第二和第三个领域涉及观测到的重力变化的反演，并处理两种最近或新开发的反演方法，这两种方法的特点是能够产生一套不同的解决方案，这些解决方案可以根据来自其他地球科学学科或解释者的认知的附加独立约束进行分析和区分。考虑到这一点，最终目标是更好地了解火山动荡或火山重新唤醒的机制和过程，并预测随之而来的活动和影响的威胁。
The aim of this chapter is to take a look at some developments and new trends in volcano gravimetry. First, we will review the objectives of the research work within this subfield of geophysics, discuss the data and methods it uses, and outline the outputs it strives for. Then, we will turn our attention to three areas where innovative approaches possibly can forward this field of study. The first has to do with the coupling between vertical deformations of the topographic surface (elevation changes) and the observed gravity changes or, in other words, with the removal of the deformation-induced gravimetric signal from the observed gravity changes to obtain the net gravity changes caused by volcanic signals. The second and third areas regard the inversion of the observed gravity changes and deal with two recently or newly developed inversion approaches that both are characterized by the ability to produce a suite of diverse solutions that can be analyzed and discriminated based on additional independent constraints stemming from other earth science disciplines or from the cognition of the interpreter. With this in mind, the final goal is a better understanding of the mechanisms and processes of volcanic unrest or reawakening of a volcano and forecasting the threat of consequent activity and impacts.
