Growth , structure , instability and collapse of Canarian volcanoes and comparisons with Hawaiian volcanoes
Recent onshore and offshore investigations in the Canarian archipelago, especially in the western islands of La Palma and El Hieno, have greatly improved the understanding of the genesis and evolution of these islands and allow interesting comparisons with other hotspot-induced oceanic island volcanoes, especially the Hawaiian archipelago. Genesis induced by hotspot activity and, consequently, ...
متن کاملMonitoring Volcanoes using Seismic Noise Correlations*
In this paper, we summarize some recent results of measurements of temporal changes of active volcanoes using seismic noise cross-correlations. We first present a novel approach to estimate volcano interior temporal seismic velocity changes. The proposed method allows to measure very small velocity changes (≈ 0.1%) with a time resolution as small as one day. The application of that method to Pi...
متن کاملCross-Calibration of RGB and Thermal cameras with a LIDAR
In this paper we present a method for combining data from an RGB camera, a long-wave-infrared (LWIR) thermal camera, and a LIDAR to obtain a registered RGB-depththermal (RGBDT) point cloud. Our method assumes that the intrinsic parameters of the cameras are known. For geometric calibration of the thermal camera, we discuss the calibration target used. For cross-calibration, our method requires ...
متن کاملCalibration of uncooled thermal infrared cameras
The calibration of uncooled thermal infrared (IR) cameras to absolute temperature measurement is a time-consuming, complicated process that significantly influences the cost of an IR camera. Temperaturemeasuring IR cameras display a temperature value for each pixel in the thermal image. Calibration is used to calculate a temperature-proportional output signal (IR or thermal image) from the meas...
متن کاملOptimal Wavelengths for Studying Thermal Emission from Active Volcanoes
Introduction: Our goal is to identify the optimal wavelengths for studying volcanic activity on Io. While better temporal, spatial, and spectral resolution is always desired, practical limitations lead one to limit both the wavelength range and spectral resolution of an observation. Our primary motivation is to assist the development of future spacecraft observations, but these results are also...
