Basis of spherical astronomy. Determination of the horizontal component of the magnetic field and the declination. Lamont and Gauss-s positions. Basics of inverse problems. Geiger-s method for earthquake location. Graphical method for the fault-plane solution on Schmidt net.
Students will be able to:
define the geomagnetic elements,
describe methods of measuring the horizontal component of the magnetic field and the magnetic declination,
discuss geomagnetic field measurements data,
describe the method of least squares and conditions for its application to locate the hypocenter of the earthquake,
display the location of the focal point of the earthquake on the basis of seismic waves phase arrival time data at seismic stations,
graphically locate the parameters of seismogenic faults for each earthquake, and describe its properties,
debate which datasets will lead to reliable and unambiguous solutions, which to ambiguous results.
