The effect on the earth's rotational change amounts to a shortening of the day of the tsunami by a few microseconds; a significant figure to those timekeepers and astrophysicists that maintain such things, but a rather insignificant change related to everyday life as well as to the earth's climate, with no affect on the earth's weather patterns. This is no unusual weather anticipated because of the earthquake's rather minor impact to the earth's rotation. In general, such changes in day length  More...

On March 19, 2011, the Moon will be at its closest point to Earth in 18 years, an event that is known as a “lunar perigee”. Also popularly referred to as the Supermoon , this is simply a situation in which the moon is slightly closer to Earth in its orbit than on average, and this effect is most noticeable when it occurs at the same time as a full moon. So, the moon may seem bigger although the difference in its distance from Earth is only a few percent at such times; and this sit  More...

Starting April 13, 2014, NOAA will no longer print traditional lithographic (paper) nautical charts, but will continue to provide other forms of nautical charts, including print on demand charts and versions for electronic charting systems.

The lowest sea-level pressure ever recorded 870 millibars (or 25.69 inches of mercury) in the storm Typhoon Tip. It was recorded 300 miles west of the island of Guam in the Pacific Ocean at latitude 16 deg 44 min north, longitude 137 deg 46 min east, on Oct. 12, 1979. A hurricane hunter plane flying through the Category 5 storm's eye of Wilma, on October 19th of 2005 found a minimum central pressure of 882 millibars, this would be an all-time record for an Atlantic storm surpassing the record s  More...
