When we pluck a string fixed at both ends, then this will creating a standing wave. We can get some insights on the behavior of the propagating wave by considering normal modes or free oscillations of the string. A wave... Continue Reading →

Based on problem 3.7 chapter 3 of Introduction to Seismology (Shearer) (COMPUTER) In the case of plane-wave propagation in the x direction within a uniform medium, the homogeneous momentum equation (3.9) for shear waves can be expressed as ,where u... Continue Reading →

The fault plane is characterized by its normal vector and the direction of its motion is given by the slip vector. Here, we calculate the normal vector and the slip vector for a given fault geometry. The orientation of the... Continue Reading →

We have calculated the auxiliary fault plane solution using the input of main fault solution in perl. Here, we do the same in Fortran. And we will also plot to solution to visualize the results. Fortran Code to get the... Continue Reading →

A travel time curve is a graph of the time it takes a seismic ray to reach the station from an earthquake versus the distance of the earthquake to the station (epicentral distance). Here, we calculate the travel time curve... Continue Reading →

We can use the power of Fortran to do computation of large data set and then we can use Gnuplot to visualize the results. Here, we take a simple example to see how we can do that. Let us take... Continue Reading →

This program will randomly pick a value and the user is prompted to enter their guess. It will keep counting your number of attempts to reach the value stored by the system. The lower the number of guesses you have,... Continue Reading →
