en There is growing evidence in recent decades that âpro-cyclicalâ macroeconomic management (i.e., imprudent fiscal, monetary and credit expansion during a boom, followed by substantial fiscal and monetary contraction after a downturn) has had serious adverse effects in many developing countries.
seismograph. A seismograph, or seismometer, is an instrument used to detect and record earthquakes. Generally, it consists of a mass attached to a fixed base.During an earthquake, the base moves and the mass does not. The motion of the base with respect to the mass is commonly transformed into an electrical voltage.eismograph. A seismograph, or seismometer, is an instrument used to detect and record earthquakes.

scientist The size of an earthquake depends on the size of the fault and the amount of slip on the fault, but scientists cant measure it with a tape because it is so deep in the ground. So how do they measure an earthquake? They use the seismogram recordings made on the seismographs at the surface of the earth to determine how large the earthquake was. A small wiggly line that does not wiggle a lot means a small earthquake, and a big wiggly line that wiggles a lot means a large earthquake.
