What do we know that Tsunami alerts are sent after the massive Russian earthquake

The massive Earthquake of Magnitude 8.8 Magnitudes of the Russian coast has activated Tsunami warnings across the Pacific.

Earthquakes, near Russian Kamchatka Peninsula, at 11:25, (00:25 BST), is believed to be one of the most powerful recorded.

More than two million people have ordered Japan to evacuate in some places on the west coast of Russia and the US.

Alerts have also been given in China, Philippines, Indonesian, New Zealand and as far as Peru and Mexico.

Videos in the city of Severo-Kurilsk, in Russia’s city, shown large buildings of the past. The authorities say that 4m (13ft) waves flooded the port and fish processing facility, and the vessels entered through their mooring. The Power Grid was also damaged in the Russian Sakhalin region.

In Japan, about 1.9 million people have been asked to evacuate and the authorities asked the neighbors to reach the ground higher. The initial waves that arrive in the country have been relatively small, but his meteorological agency say that 3m (9.8ft) could grow.

In Hawaii, officials who warned 10ft waves first fell to the level of tsunami warning that covers the island.

This means that strong waves, small floods and a potential of hard currents, but an important tsunami is not expected. Returning these evacuates home, Stephen Logan, Director of the Hawaiian Emergency Management Agency, said.

So far, damage is not as bad as the first fear, even if the waves of tsunami are following the peaceful ocean.

“Now, scientists are running new models to try to improve the initial forecasts,” Chris Goldfinger, Oregon State Professor of Maritime Geology told BBC breakfast.

“Each country, each port and each coast will live a very specific site. Some places will be quite minimal, some are quite serious.”

The amount of impact depends largely on the path of the Russian Kamchatka Peninsula. Fields directly aligned in the southeastern southeast of Epicenter – is expected to be the most affected.

He said about “eight and nine hours” to reach a Tsunami of Kamchatka to the west coast of the US.

Earthquake hit the local time around 11:25 (00:25 am BST) on Wednesday.

Tsunami waves hit parts of the west coast of North America at 12.2000 (09.2000 BST).

The waves hope Washington’s Tacoma port in 220 (11.20 decades in BST) and Nome, Alaska (12.20 20).

“Tsunami is a good rule for traveling the speed of a jet aircraft,” Helen Janiszewski, the assistant professor of the Department of Geophysics and Tectonics at the University of Hawaii, told BBC.

“So long for a long time you would travel to travel by plane, how long it takes to go to another place from the waves Quake Epicenter,” he said.

The US Geological Survey said the earthquake was striking to a depth of 19.3 km (12 miles) and focused on 119 km from Petropavlovsky-Kamchatsky.

Initially it was recorded as an earthquake of 8.0 magnitude, but later they were reviewed. Numerous strong aftershocks are recorded.

The sixth earthquake in history is linked to the 2010 earthquake in Biobia, Chile and the 1906 earthquakes in Emeraldas, Ecuador.

The fifth largest earthquake was also in Kamchatka Krai, Russia in 1952. “The world’s first magnitude has been 9 earthquakes.”

Comparing, the 2004 Ocean Indian earthquakes and Tsunami – more than 227,000 people were killed – 9.2-9.3 magnitude earthquakes.

This turned 160 km from the coast of the west of Sumatra, Indonesia – a high-density area. The Russian Kamchatka Peninsula has a very low population density.
