Earthquake of 7.4 on Richter caused tsunami warning in the US

A seismic intensity of up to 7.4 on the Richter scale rocked the Aleutian volcanic island chain, in the US state of Alaska. Tsunami warning was given, but was retracted after an hour.

AFP quoted the US Geological Survey (USGS) as saying that the earthquake occurred around 18:00 local time, at a depth of about 40 km at the Fox Island group, located in the Aleutian island chain. Following the earthquake is a series of aftershocks with smaller intensity.

The shock recorded was up to 7.4 Richter . The Alaska Tsunami Warning Center and the west coast (WCATWC) had to issue a warning in coastal areas from the Unimak Strait to the Amchitka Strait. If the tsunami occurs, the first wave will reach Adak city of the Aleutian island chain at about 12h12, ie over 2 hours after the earthquake.

The WCATWC recommends that people living in coastal areas and in remote island chains need to land immediately, to reach higher lands to avoid the risk of tsunamis. " Houses and small buildings are not designed to counter the impact of tsunamis. Don't stay there at this time, " WCATWC said.

The latest information from the earthquake zone indicates that WCATWC has withdrawn the tsunami warning after an hour . This development is consistent with the assessment of the Pacific Tsunami Warning Center in Hawaii, saying that "there is no warning " after the earthquake occurred about 1,600 km from Alaska's largest city.

There is currently no information regarding human and human losses in Alaska after the earthquake, but the people here are frightened by this rare tremor. A porter named Jim Paulin from Dutch harbor said hundreds of people had pulled together into high hills around the breeding grounds to avoid the tsunami.
