A Portable Seismic Array for Undergraduate Geophysics Instruction

地质和地球物理科学系是 配置和调整新开发的便携式数字 地震仪（PASSCAL）用于各种本科生 实验室经验，从入门实验室到 高年级实验室到高年级独立工作 （Thesis）。 正在使用五个便携式三通道系统 在一个或两个区域部署小型（500米）地震检波器阵列， 至少有一个三分量地震仪 用于研究剪切波。 学生们正在使用的设备： 1）研究小地震（活动区）的局部台阵; 2)用于折射或反射研究的局部线性阵列; 3)层析成像的工程地震学演示; 建筑物共振的工程地震学论证; （5）地震台站的地震监测业务。 每种部署模式都适用于介绍性实验， 上流社会的实验室，或上流社会的研究，这取决于 在多大程度上给予学生独立 负责开展工作。

The Geological and Geophysical Sciences Department is configuring and adapting newly developed portable digital seismometers (PASSCAL) for use in a variety of undergraduate laboratory experiences ranging from introductory laboratory to upperclass laboratory to Junior and Senior Independent Work (thesis). Five portable three-channel systems are being used to deploy small (500m) arrays of geophones in one or two dimensions, and with at least one three-component seismometer for study of shear waves. Students are using the equipment in: 1)a local array for study of small earthquakes (active region); 2) a local linear array for refraction or reflection studies; 3) a engineering seismology demonstration of tomography; 4) a engineering seismology demonstration of building resonances; and 5) seismic station operations for earthquake monitoring. Each deployment mode is suitable for introductory labs, upperclass labs, or upperclass research, depending on the extent to which the students are given independent responsibility for conduct of the work.
