Shown is an image comparing a powerful #earthquake which shook Indonesia at 15:35 hrs UTC, the focal depth was a deep ~539kms. The figure below demonstrates how the #teleseismic waves #propagated across Spring TX, Oakton VA and Boston MA. How could you explain the differences in first wave phase arrival times and amplitudes?
The M6.5 earthquake epicenter is near Kampungbajo, Indonesia. At this time, no tsunami alert has been issued. It’s too early for damage and injury reports.
