If you only have data from two recording stations, the main difficulty you will encounter is the inability to accurately locate the exact epicenter of an event such as an earthquake. This is because pinpointing the epicenter requires triangulation, which needs data from at least three stations to form a triangle and precisely determine the location. With only two stations, you can estimate the distance to the epicenter from each station, but you cannot find a unique intersection point, leading to ambiguity in location. This limitation increases uncertainty in analysis and makes it harder to distinguish true signals from noise

. In summary:

• Two stations provide limited geographical coverage.
• Triangulation to find an exact epicenter is not possible.
• Location and characteristics of the source remain uncertain.
• More stations improve accuracy and reliability of results.

Therefore, having data from only two recording stations restricts the precision and confidence in locating and analyzing the source of recorded events.
