Tag points at a chart showing seismic waves observed in south korea

Based on the chart, I'll try to identify the key points:

Point 1: The chart appears to show the arrival times of different types of seismic waves (P-waves and S-waves) from a seismic event in South Korea.

Point 2: The x-axis represents time, with the earliest arrival times on the left and the latest on the right.

Point 3: The y-axis likely represents the distance from the epicenter of the seismic event, with the closest stations at the bottom and the farthest at the top.

Point 4: The chart shows two distinct arrivals of seismic waves: P-waves (red) and S-waves (blue). P-waves are faster than S-waves, which is why they arrive first.

Point 5: The P-waves arrive at the closest stations (bottom of the chart) around 10-15 seconds after the event, while the S-waves arrive around 20-25 seconds later.

Point 6: As the distance from the epicenter increases (moving up the chart), the arrival times of both P-waves and S-waves increase, indicating that seismic waves travel at different speeds and take longer to reach farther stations.

Point 7: The chart suggests that the seismic event was likely a shallow earthquake, as the P-waves and S-waves have similar arrival times and velocities.

Point 8: The chart may also indicate that the seismic event was relatively small, as the amplitude of the seismic waves (not shown on this chart) would likely be smaller for a smaller event.

Please let me know if you'd like me to clarify any of these points or if you have further questions!
