Earthquakes News & Videos - ABC News But using a technique called backprojection, which analyzes delays between seismic waves to determine how fast they are traveling, the team realized that supershear earthquakes are just as common in the ocean as on dry ground they just have been historically a lot harder to monitor. Their analysis found that in addition to five previously confirmed supershear earthquakes documented in their data set, a further seven also met the supershear criteria. Meltzner, who is now a geologist at Nanyang Technological University in Singapore, returned to study the corals around Sumatra year after year to untangle the many records they hold.
