The Eastern Pacific is about as active as the Western Pacific, EXCEPT, the origins of these storms are all from near shore tropical areas where water vapor can be sourced. It is HOWEVER a very odd year. The Typhoons themselves have not that high a vorticity. The highest was a Cat 1 Typhoon. The first of the season that saw winds of 115 mph. After that the storms lost their vorticity, BUT, the damage to land and people is remarkable. More so than I would expect. These other storms are still pushing huge amounts of water ashore, similar to the Katrina phenomena. There was also a significant earthquake near shore Japan at the very same time. There is something odd about the damage and water movement.

The Wastern Pacific is seeming more activity than the Atantic. But, the same is true when it comes to water vapor. As soon as these storms start to move north along the face of Earth and away from the Intertropical Equatorial Convergence Zone where they derive their source of water vapor they weaken dramatically.
One hurricane this season in the Atlantic, at sea, only achieved a Tropical Depression Status with lowest central pressures of 1006. The years since 2005 are primarily anemic to say the least. There hasn't been a repeat of that year which was a record breaker. It was orginally thought that might occur in a warming climate change planet. That isn't the case. As the surface of Earth heats, the 'water vapor' moves vertically, not horizontally. The water vapor is far above the origins of hurricanes and they cannnot be sustained.
