Tsunami threat to large earthquakes in Russia's Pacific coast | Earthquake messages

Three earthquakes with a size of 7.4, which were recorded near Petropavlovsk-Kamchatsky, the capital of the Russia's Kamchatka region.

The Pacific Tsunami Warning Center (PTWC) says that on the Kamchatka peninsula in Russia after three earthquakes – the larger one with a size of 7.4 – is more near Tsunami waves.

The warning was issued earlier on Sunday after the quakes off the Pacific coast of Russia, according to the United States Geological Survey (USGS).

The epicenters of a series of earthquakes with 6.7 and 5-am Sunday were about 140 km east of Petropavlovsk-Kamchatsky, the capital of Russia Kamchatka region, which has more than 160,000 inhabitants.

According to the USGS, the quakes hit the same area off the Petropavlovsk-Kamchatsky coast within 32 minutes.

The earthquake of size 7.4 was at a depth of 20 km (12 miles). There were no immediate reports on victims.

The PTWC initially said there was a danger of large tsunami waves, but later downgraded her warning before she finally said that the danger had passed.

The Russia's Ministry of Emergency also published a tsunami warning after the second quake and asked the residents of coastal settlements to keep away from the shore.

A separate tsunami clock for the state of Hawaii was later lifted.

The German GFZ monitor also confirmed that at least one earthquake in size 6.7 was recorded in the Kamchatka region on Sunday. GFZ later updated to size 7.4.

Petropavlovsk-Kamchatsky is located in the Kamchatka region, which faces the Pacific northeast of Japan and west of the US state of Alaska, over the Bering Sea.

The Kamchatka Peninsula is the meeting point for the Pacific and North American tectonic plates and makes it a seismic hot zone. Seven main darts of 8.3 or higher have hit the area since 1900.

On November 4, 1952, an earthquake of strength 9 in Kamchatka caused damage, but no deaths were reported, although 9.1 meters (30 feet) were triggered in Hawaii.
