Remote Sensing of Volcanic Hazards and Their Precursors

Proceedings of the IEEE, 2012

Ash, tephra, and gas ejected during explosive eruptions pose a major far- reaching threat to population, health, and air traffic. Lava flows, lahars, and floods from ice-capped volcanos, as well as landslides that have a potential for tsunami generation if they reach into sea or lakes, can also have a major influence. Remote sensing contributes to the mitigation of these ...


Surface analysis of failed vacuum reeds

Proceedings of IEEE Holm Conference on Electrical Contracts, 1994

  • Remote Sensing of Volcanic Hazards and Their Precursors

    Ash, tephra, and gas ejected during explosive eruptions pose a major far- reaching threat to population, health, and air traffic. Lava flows, lahars, and floods from ice-capped volcanos, as well as landslides that have a potential for tsunami generation if they reach into sea or lakes, can also have a major influence. Remote sensing contributes to the mitigation of these hazards through the use of synthetic aperture radar interferometry (InSAR) and spectroradiometry. In the case of InSAR, displacements of a volcano's surface can be interpreted in terms of magma movement beneath the ground. Thus, the technique can be used to identify precursors to eruptions and to track the evolution of eruptions. Recent advances in algorithm development enable relative displacements over many kilometers to be measured with an accuracy of only a few millimeters. Spectroradiometry on the other hand allows monitoring of a volcanic eruption through the detection of hot spots, and monitoring and quantification of the ash and SO<sub>2</sub> emitted by volcanos into the atmosphere. The tracking of ash plumes during eruptions assists in the identification of areas that should be avoided by aircraft. Here we present a review of these two remote sensing techniques, and their application to volcanic hazards.

  • Surface analysis of failed vacuum reeds

    The failure of vacuum reeds mainly appears as the switch is off but the current is still retained. People used to call it "adhesion" of the contacts. For new type of reeds, a thick layer of tungsten is plated on the blade surface for improving the operation life. Experimental results show that tungsten plating can greatly increase the operation life. However, failure of the reeds are still found. Micro-investigation of the failed reeds shows that "volcanos" or craters are observed on the contact surfaces which is the result of "explosion". It is reasonable to deduce that when arcing is formed at the contact surface, temperature may rise rapidly to very high rating. If the temperature on the tungsten plating is high beyond its softening point (1000/spl deg/C), the surface hardness is reduced. When the temperature of the blade underneath the tungsten plating increased above its melting point, the expansion of the iron alloy, and the vapor pressure may form an extremely high force upward to extrude through the plating. Metal vapor concentrated between cathode and anode may cause the retention of electric current. Cracks seem to have no responsibility for the failure.

Due to the number of experiments on the satellite, the available times for the capture of images have been limited. The images captured to date have undergone initial analysis, although further work is required for calibration, as well as the adaption of the hotspot detection and characterisation algorithm.

  • A Method to Differentiate Degree of Volcanic Reservoir Fracture Development Using Conventional Well Logging Data—An Application of Kernel Principal Component Analysis (KPCA) and Multifractal Detrended Fluctuation Analysis (MFDFA)

    Fracture is the main pore space for volcanic reservoir, serving as the controlling factor of reservoir productivity. Conventional well logging data often fail to fracture characterization and classification in volcanic reservoir since the degree or extent of the fracture development varies in scales in different locations. A method for fracture developing degree discrimination, based on a combinational algorithm of kernel principal component analysis (KPCA) and multifractal detrended fluctuation analysis (KPCA-MFDFA), is proposed. The first kernel principal component (KPC_1), mostly characterizing the reservoir property, is extracted from conventional well logging data. Multifractal parameters, such as multifractal dimension, mass exponent, multifractal spectrum, and singularity strength, are calculated by MFDFA. A cross-plot between the maximum multifractal dimension difference and range of singularity strength is established to investigate the relationships between multifractal parameters and fracture developing degree.

  • Focusing attention on objects of interest using multiple matched filters

    In order to be of use to scientists, large image databases need to be analyzed to create a catalog of the objects of interest. One approach is to apply a multiple tiered search algorithm that uses reduction techniques of increasing computational complexity to select the desired objects from the database. The first tier of this type of algorithm, often called a focus of attention (FOA) algorithm, selects candidate regions from the image data and passes them to the next tier of the algorithm. In this paper we present a new approach to FOA that employs multiple matched filters (MMF), one for each object prototype, to detect the regions of interest. The MMFs are formed using k-means clustering on a set of image patches identified by domain experts as positive examples of objects of interest. An innovation of the approach is to radically reduce the dimensionality of the feature space, used by the k-means algorithm, by taking block averages (spoiling) the sample image patches. The process of spoiling is analyzed and its applicability to other domains is discussed. The combination of the output of the MMFs is achieved through the projection of the detections back into an empty image and then thresholding. This research was motivated by the need to detect small volcanos in the Magellan probe data from Venus. An empirical evaluation of the approach illustrates that a combination of the MMF plus the average filter results in a higher likelihood of 100% detection of the objects of interest at a lower false positive rate than a single matched filter alone.

  • Improving city infrastructure resilience capacity: Water-supply network case study

    Main goal of research in this paper is to improve city infrastructure resilience capacity as well as management process of water supply network. Namely, water supply network is located over the wide city area, typically managed by company established for that purpose owned by city government. Water supply network is very important part of the city infrastructure. Hence, it is necessary to ensure high-quality and reliable water supply network management process. Our research is focused on mapping of telecommunications network management principles into water supply network management. Complete network view is graphically and geographically oriented using GPS based network elements coordinates. Real-time network control and management is based on network inventory management system which is presented in our previous work. Data from the real network are included in network management process using telemetry techniques and will enhance network management process. Finally, network model and relevant real-time data are integrated into the complete system that will cover all city infrastructure, acting as infrastructure data interchange portal usable especially in the case of disasters such as flooding, earthquakes, volcanos, etc. Indirectly, citizens will communicate with this platform through different users or services using telecommunications infrastructure.

  • Detection of crustal deformation induced by earthquake and volcanic activities in Java, Indonesia

    Both earthquake and volcanic activity induce crustal deformation, though the mechanism and appearance of deformation are different. Many successful cases of differential SAR interferometry for individual seismic and volcanic deformation detection have been reported, however in the area where earthquake and volcanic activities coexists, crustal deformation becomes much complicated for the double causes. Less was reported on how the two crustal motions influence each other in interferograms. In May 2006, two active volcanos erupted after the Ms 6.3 Indonesia Java earthquake. Interferometric Envisat ASAR data were used for measuring the crustal deformation co-affected by earthquake and volcanic activities and we got new knowledge about the complicated deformation and the potential of IN SAR.

  • Temperature retrieval for Earth's surfaces using BIRD (Bi-spectral InfraRed detection)

    The Earth's surface temperature is a key parameter for the understanding of the energetic and hydrological balance of the Earth. Continuous measurements of the global temperature distribution provide information on its changes and impact on the global climate. With the BIRD small satellite mission (size: 158 cm/spl times/64 cm/spl times/52 cm, mass: 85 kg) a new generation of imaging infrared sensors to be used in space will be tested. The main scientific tasks include the developing of temperature retrieval methods for high-temperature- events like fires, volcanos etc. as well as for "normal" Earth's surface temperature like the temperature of vegetation, etc.-the fire surrounding temperature. BIRD, a multi-spectral sensor system, is slated to be launched in 2000. It consists of two IR cameras (3.4-4.2 /spl mu/m (MIR-Mid InfraRed) and 8.5-9.3 /spl mu/m (TIR-Thermal InfraRed)) as well as a stereo camera WAOSS (Wide-Angle Optoelectronic Stereo Scanner) where the spectral ranges lie within the visible (VIS) and the near infrared (NIR). Two temperature retrieval methods customized for the BIRD channel constellation are established. One method is based on a multi-spectral regression (referred to as "regression"-approach) using brightness temperatures of both channels at the top of the atmosphere. The other approach recovers land surface emissivity and temperature from ground radiances utilizing a "Temperature Independent Spectral Index for Emissivity" (referred to as "TISIE"-approach). Both methods lead to equivalent temperature retrieval errors, but the "TISIE"-approach does not need an a priori knowledge of the emissivity.

  • Air-borne magnetometers

    Developed under the impetus of the submarine menace of World War II, the airborne magnetometer has found many peacetime uses. Navy airplanes equipped with magnetometers for exploration of Antarctica were used in the recent United States Navy expedition. An expedition now is studying the Aleutian Alaskan volcanos and the Aleutian submarine trench. From there it will proceed to Hawaii and Bikini.

  • Magnetic braking of the Earth's rotation

    The Earth's rotation is decelerating at a rate of 8.8*10 exp-20 rad/s. Thus, a leap second is added to the year every two to four years. This deceleration is small, but the Earth weighs 6*10 exp 24 kg. A prony brake that achieves this deceleration would release 5.14*10 exp 11 kW, the equivalent of 514,000 1-GW nuclear power plants. Tides, volcanos, Coriolis-generated ocean currents and winds cannot absorb this much power. This leaves the induction generation which produces the Earth's magnetic field as the most likely absorber of the deceleration power. The efficiency of this inaccessible induction generator cannot be calculated. However, it is thought that correlation of the Earth's deceleration with its 0.09% weakening magnetic field could provide insight into the power generation process.<<ETX>>
