A powerful underground tremor was recorded yesterday east of the islands of Fiji. Its magnitude was 8.2 on the Richter scale. The epicenter lay at a depth of 563.4 km.
After the main shock there were several aftershocks, the most powerful of which was a tremor magnitude 6.3 on the Richter scale. The epicenter of this earthquake also lay at a great depth – 561 km.
Despite the very large magnitude of the earthquakes, there was no warning about the tsunami due to the huge depth at which these tremors occurred.
