Africa-Press – Cape verde. <\/strong><\/span>Last August, a strong earthquake occurred near the South Sandwich Islands in the Atlantic Ocean. Initially, the United States Geological Survey reported that the tremor was 7.5 in magnitude on the Richter scale, before updating it to 8.2 the next day.<\/p>\n

Scientists from the California Institute of Technology claim to have uncovered the source of a mysterious worldwide tsunami that occurred last year. The event left the researchers bewildered, as the earthquake that preceded the tsunami was too deep (47 kilometres below the Earth\u2019s surface) to trigger it.<\/p>\n

The study, published this week in Geophysical Research Letters, shows that the earthquake was in fact a series of sub-quakes that spread over several minutes. One of them had a magnitude of 8.2 on the Richter scale and was just 15 kilometres below the surface.<\/p>\n

Despite its strength, the earthquake was \u201calmost invisible\u201d to monitoring systems because it was “buried” in the tangle of seismic waves produce by other sub-earthquakes.<\/p>\n

Researchers believe that the “silent” tremor triggered the tsunami that rippled around the globe. It spread to the North Atlantic, Pacific, and Indian Oceans, reaching shores over 10,000 kilometres away.<\/p>\n

Although the tsunami was small and did not cause any damage, researchers stress that such complex earthquakes can pose a significant risk. The researchers’ next goal is to automate the detection of such complex earthquakes, as is currently done for simple tremors.<\/p>\n
