An invitation issued by Unesco under the Volcanologist Exchange Programme has given opportunity to the authors to visit Mayon Volcano, South Luzon, The Philippines, which was reported to have shown an increasing activity early May this year. The first increasing volcanic phenomenon was observed on May 3, and harmonic tremors were recorded the following days. The precaution measures have then be…
During the month of January the growth of lava dome continued slowly. From time to time at night glares above the dome could be observed. On January 15 a lava avalanche entered the upper course of R. Batang. In February the growth of lava dome seemed to cease completely.
The purpose of this report is to indicate the exixtence of a phreato-magnetic volcanic center in the densely populated area south of Cirebon city. On July 6 and July 29, 1988, I examined the geology of the area near the reservoir (waduk) Setu Patok , located 8 km south of Cirebon city (Figure 1) [108 degrees, 47', 10" S; topographic map, 1966 series, sheet 4722 IV, Tjirebon].
Integration of GIS and Remote Sensing explores the tremendous potential that lies along the interface between GIS and remote sensing for activating interoperable databases and instigating information interchange.it concentrates on the rigorous and maticulous aspects analytical data matching and thematic compatibility-the true roots of all branches of GIS/remote sensing applications .however ,cl…
The magnetotelluric method is one of many methods based on measuring the electrical resistivity of the subsurface as an indirect means for studying geology, but it is a method that caught the imagination of many explorations when it was first described nearly three decades ago by Cagniard and Tikhonov.
For more than fifty years this has been the outstanding reference work on photographic technology. Now the expanded seventh edition- completely rewritten, resigned, and reset provides today’s most comprehensive and up to date source of information on photography and reprography.
In the broadest sense, remote sensing encompasses the total observational process from remote platforms, It typically entails the use at a distance (as from aircraft, spacecraft or ship) of any system for gathering information pertinent to the environment.
The objective of landslide hazard zonation is subdivision of an area into zones with an equal susceptibility to or probability for the occurrence of mass movements. Many different methods have been proposed in the literature. These methods have in common the combination and integration of a series of input maps, which is a time consuming process if done manually.
