抽象的。监测火山活动对于了解每座火山的特性和向民众提供预警系统十分重要。监测设备可能很昂贵，因此监测的程度因火山和国家而异，许多火山根本没有监测。本文介绍了无线传感器网络（WSN）的发展，能够收集地球物理测量远程活火山。我们的主要目标是创建一个灵活的，易于部署和易于维护，适应性强，低成本的无线传感器网络的临时或永久监测地震震颤。无线传感器网络能够在数万平方米的区域内轻松安装传感器阵列，从而计算出引起地震震颤的岩浆运动的位置。该无线传感器网络可以通过在本地记录数据用于以后的分析，或者通过连续地将其以真实的时间传输到远程实验室用于实时分析来使用。我们提出了一组测试，验证我们的无线传感器网络的不同方面，包括部署在吊桥上测量其振动。
Abstract. Monitoring of volcanic activity is important for learning about the properties of each volcano and for providing early warning systems to the population. Monitoring equipment can be expensive, and thus the degree of monitoring varies from volcano to volcano and from country to country, with many volcanoes not being monitored at all. This paper describes the development of a wireless sensor network (WSN) capable of collecting geophysical measurements on remote active volcanoes. Our main goals were to create a flexible, easy-to-deploy and easy-to-maintain, adaptable, low-cost WSN for temporary or permanent monitoring of seismic tremor. The WSN enables the easy installation of a sensor array in an area of tens of thousands of m2, allowing the location of the magma movements causing the seismic tremor to be calculated. This WSN can be used by recording data locally for later analysis or by continuously transmitting it in real time to a remote laboratory for real-time analyses. We present a set of tests that validate different aspects of our WSN, including a deployment on a suspended bridge for measuring its vibration.
