Seismographs still, but computers make it faster and easier to use
Before computers became widely used, scientists identified the location of an earthquake using a network of seismometers that detected the seismic waves produced by the event. By analyzing the arrival times of the waves at multiple stations, scientists could triangulate the exact location of the earthquake's epicenter.
They used permanently-mounted seismometers around the world. Given the readings of all of them, one could triangulate the earthquake's position. Come to think of it, the same system is used today . . . computers just make the process faster and more automatic.
It didn't because before the scientific method there were no scientists. Scientists are professionals that employ the scientific method to do their work.

Yes, scientists can predict volcanic eruptions, but only to a certain extent of accuracy. One method is to use earthquakes. Earthquakes usually increase and become more violent before a volcanic eruption
Yes they can but only a couple of minutes before it strikes. Scientists know where earthquakes could occur but the when is unknown until a few minutes beforehand.
Correct, earthquakes cannot be reliably predicted in terms of when they will occur, where they will happen, and how large they will be. Scientists can forecast the likelihood of earthquakes in certain areas based on historical data and ongoing monitoring, but predicting specific times and locations remains a significant challenge.
environmental impact, energy production costs, AND benefits of the new production method
They can calculate intensity based on how the earthquake was felt at different places and what damage occurred from old newspaper reports and other historic documents.
Electro-Mechanical Computers were used before first generation of computers.
No single change occurs before all earthquakes.
