西印度群岛大学地震研究中心（SRC），以前称为地震研究股（SRU），位于东加勒比的特立尼达岛。该中心自1953年以来一直在运行其火山和地震监测网络。从那时起，该网络已经升级了五次，产生了五代地震网络拓扑结构（即，类）。第1类由自主操作的摄影记录站组成，这是一种纯模拟配置。从第2类到第5类（当前级别），网络在范围、复杂性和能力方面不断增长。该网络的发展是使用最先进的仪器以及后缘技术（例如，模拟传输），以允许可持续性的方式使用。通过这种方式，该网络能够应对与在岛弧俯冲带作业有关的科学和技术挑战，该岛弧俯冲带面临飓风等其他自然灾害。为了应对其业务限制，SRC制定了几项战略，这些战略有助于：（i）扩大网络，以满足更及时和准确地监测地质灾害的需求，（ii）扩大监测技术的范围（例如，cGPS，地球化学），（iii）捕获研究级科学数据和（iv）降低运营成本。
The Seismic Research Centre (SRC), formerly known as the Seismic Research Unit (SRU), of the University of the West Indies is located on the island of Trinidad in the Eastern Caribbean. The centre has been operating its volcanological and seismological surveillance network since 1953. Since that time, the network has been upgraded five times resulting in five generations of seismic network topologies (i.e., Classes). Class 1 consisted of autonomously operated photographic recording stations, a purely analogue configuration. From Class 2 to Class 5 (current class) the network has continuously grown in scope, sophistication and capability. The evolution of the network was carried out using a combination of state-of-the-art instruments as well as trailing edge technology (e.g., analogue transmission) used in a manner that allows for sustainability. In this way, the network has been able to address the scientific and technical challenges associated with operating in an island arc subduction zone which is exposed to other natural hazards such as hurricanes. To counter its operational constrains the SRC has developed several strategies, which contribute to: (i) expand the network to meet the demand for more timely and accurate surveillance of geohazards, (ii) broaden the range of monitoring techniques (e.g., cGPS, geochemical), (iii) capture research grade scientific data and (iv) reduce operational costs.
