This Weekend's 'Supermoon' Will be Year's Largest

how can you call this science?
On March 11, 2011 the Japan Earthquake hit

This Weekend's 'Supermoon' Will be Year's Largest | Supermoon Full Moon | Space.com: Though the unusual appearance of this month's full moon may be surprising to some, there's no reason for alarm, scientists warn. The slight distance difference isn't enough to cause any earthquakes or extreme tidal effects, experts say.

However, the normal tides around the world will be particularly high and low. At perigee, the moon will exert about 42 percent more tidal force than it will during its next apogee two weeks later, Rao said.

The last supermoon occurred in March 2011.

how can 42% increased tidal force NOT be significant??

the Volume of Earth's Oceans: Volume in Thousands of Cubic Kilometers of water the Oceans is 1,310,302 Thousand KM3 is salty sea water. That's 1000kg per km3...  and moving this force 42% more is a big deal, look water a 2m wave can do:

here is the Japanese tsunami debris? Only the albatrosses know

The earthquake analysis – released in January 2012 – came from the Center for Disaster Management and Risk Reduction (CEDIM) in Germany. According to their report, earthquakes and their consequences, including tsunamis and landslides, caused damages of $365 billion U.S. dollars. More than half of that was from the March 2011 Tohuku earthquake and tsunami.

According to the CEDIM report, in 2011, over 20,000 people died and about a million people lost their homes globally, due to earthquakes and their effects. The two countries hit hardest by earthquakes were New Zealand, with a large earthquake near Christchurch in February, 2011 – and Japan. In 2011, the earthquakes and their aftereffects destroyed or damaged more than 1.7 million buildings globally. Of these, Japan had more than one million damaged buildings.

Saturday, when the "supermoon" swings within 221,802 miles (356,955 kilometers) of Earth — its closest approach of the entire year. Because the moon's orbit is not exactly circular, there is a 3-percent variation in its closest approaches to Earth each month. The average Earth-moon distance is about 230,000 miles (384,400 km).

that's 27,445 km closer to the earth?  Mount Everest/  Sagarmatha / Chomolungma is only 8,848m high, not 8,848km, but only 8km - - that's 3430 Mount Everest s closer to earth moving the water here

Ocean - Wikipedia, the free encyclopedia:

The area of the World Ocean is 361 million square kilometres (139 million square miles)^[14] Its volume is approximately 1.3 billion cubic kilometres (310 million cu mi).^[6] This can be thought of as a cube of water with an edge length of 1,111 kilometres (690 mi). Its average depth is 3,790 metres (12,430 ft), and its maximum depth is 10,923 metres (6.787 mi)^[14] Nearly half of the world's marine waters are over 3,000 metres (9,800 ft) deep.^[9] The vast expanses of deep ocean (anything below 200 metres (660 ft)) cover about 66% of the Earth's surface.^[15] This does not include seas not connected to the World Ocean, such as the Caspian Sea.

The total mass of the hydrosphere is about 1,400,000,000,000,000,000 metric tons (1.5×10¹⁸ short tons) or 1.4×10²¹ kg, which is about 0.023 percent of the Earth's total mass. Less than 3 percent is freshwater; the rest is saltwater, mostly in the ocean.

how can you say that 42% more motion of this mass will have no effect?
