In recent years there has been a striking improvement in science and mathematics instruction in many high schools. This improvement is not universal, and colleges are faced with the problem of freshmen entering with widely varying degrees of preparation.
To geologist, the field is where rocks or soils can be observed in place, and field geology consist of the methods used to examines and interpret structures and materials at the outcrop. Field studies are primary means of obtaining geologic knowledge. Some studies may be as simple as visiting a single outcrop or quarry, making notes and sketches on the relations between certain rocks, and colle…
Geology has evolved greatly since I wrote the manual of field geology in the 1950’s. Advances in theory have transformed the formation mapping of the time into increasingly broader and more interpretive studies. We have much to seek at the outcrop and the rising costs of field work compel us to recognize key features the first time around.
During the last few decades groundwater availability is facing increasing pressures. Water quality and quantity deterioration. physical changes of the aquifers, related problems of salt water encroachment, land subsidence, massive drop water table, and increasing pollution from the surface water has effect the groundwater resource. Problems related to law and regulations for extraction by urban…

The geologist is concerned with every aspect of the composition and structure of the earth’s crust. His sphere of work is therefore worldwide; his main laboratory is he great out of doors where in examines rocks as they actually occur in nature.
In August, 1984, Robert Y.Koyanagi, Seismologist, and George Kojima, Electronics technician were missioned to Indonesia to evaluate the radiotelemetered seismic network (RTS) at Merapi Volcano Observatory located at Yogyakarta in Central Java.
The purpose of this assignment wa to provvide support to the seissmic program at the Merapi Vulcano Observatory (MVO) of the Vulcanological Survey of Indonesia (VSI). Instrument maintenance and data analysis support were provided for by Bruce Furukawa and Bob Koyanagi between 13 to 24 May; additional assistance in instrument maintenance was provi MVO ed by Furukawa from 25cMay to 9June.
