High in the mountains of Central Asia, work continues on a part of the Earthquake Prediction project that was begun under the U.S.-USSR Joint Agreement on Cooperation in the field of Environmental Protection of May 1972. The focus of the effort is the Nurek Dam in Tadzhikistan (see Figure 1). The filling of the 300-m-deep reservoir behind the dam was expected to cause increased levels of seismic activity in the already highly active area, giving scientists valuable opportunities to study the phenomena that take place in the earth's crust before strong quakes and possibly enabling them to identify the indicators and/or the initiators of earthquakes.
