Tectonics Observatory at Caltech

Resources & Data

The TO has acquired hardware that is key to the realization of our scientific objectives. This equipment and any data they produce are communal resources for all TO investigators. These include: GIS laboratory, Beowulf computer, Mass Spectrometer, 50 Broadband Seismometers, and Continuous GPS Geodetic Networks.

Source Models of Large Earthquakes Rapid estimation of slip maps for selected large earthquakes (Mw>7)	Animations and Graphics
GIS Laboratory Provides Geographic Information System (GIS), remote sensing, and 3D-modeling resources, for compiling and digitizing spatial and attribute data, interpreting geologic and geophysical data, and producing publication-quality maps and figures
Data Continuous GPS Arrays Geodetic networks of continuously recording GPS stations to monitor crustal motion MASE, VEOX, and CAnTO Peru Seismic Data MASE is a cooperative project involving Caltech's Tectonics Observatory, UCLA's CENS, Geophysical Institute at UNAM, and the Center for Geosciences at UNAM. The seismic component consisted of 100 broadband seismometers across central Mexico. The array ran from 2005-2007. VEOX is a follow-on to MASE and crosses southern Mexico just north of the Techauntepec Ridge. CAnTO Peru is a cooperative project involving Caltech's Tectonics Observatory, UCLA, IRD/Peru, and IGP. It is a set of passive seismic lines to be deployed in southern Peru. The first line was deployed in the summer of 2008.	Software COSI-Corr COSI-Corr (Co-registration of Optically Sensed Images and Correlation), is a software package developed with IDL (Interactive Data Language) and integrated under ENVI. It allows for precise ortho-rectification, co-registration and correlation of SPOT and ASTER satellite images as well as aerial photographs. PCAIM PCAIM (Principal Component Analysis-based inversion Method) software takes a time series of surface deformation data (such as GPS data) and from that data determines the time evolution of slip on the underlying fault. It can be used for any rate of time variation.
