FEMA National Flood Insurance Program:  

"Flood risk can, and does, change over time. Flood risks change for many reasons: new development, changes in levee classification, and environmental changes, to name a few. As a result FEMA is updating flood hazard maps across the country. These new flood maps, also, known as Digital Flood Insurance Rate Maps (DFIRMs), show flood risk at a property-by-property level.

In the U.S., tsunami early warnings are issued by two warning centers operated by the National Weather Service. The National Tsunami Warning Center (NTWC) monitors for earthquakes and issues tsunami advisories, watches, warnings, and information statements for Alaska, the U.S. mainland, U.S. Atlantic and Gulf of Mexico, Canada, and U.S. interests in the Caribbean (Puerto Rico and the U.S. Virgin Islands)^[1,2,3].

U.S. Tsunami Warning Center FAQs:

"1. Severe ground shaking from local earthquakes may cause tsunamis.

2. As a tsunami approaches shorelines, water may recede from the coast, exposing the ocean floor, reefs and fish.

3. Abnormal ocean activity, a wall of water, and an approaching tsunami create a loud "roaring" sound similar to that of a train or jet aircraft.

Extracting and processing raw resources (wood, oil, ore) to make usable materials (paper, plastic, metal) requires a lot of energy. Recycling often saves energy because the products being recycled usually require much less processing to turn them into usable materials.

Exactly how much energy is saved depends on the material in question. Let’s take two examples: glass and aluminum.

In 2017, total energy use per person (“per capita consumption”) in the United States was 300 million British thermal units (Btu).^1,2 32% of this was from industrial use, 29% from transportation, 20% from residential use, and 18% from commercial use.¹ Per-person energy use in the United States decreased by 10.7% from 2007 to 2017.³

For comparison, here is the 2015 per-person energy use (in million Btu) for a selection of other countries:⁴

"The three major fossil fuels—petroleum, natural gas, and coal—combined accounted for about 77.6% of the U.S. primary energy production in 2017:

Energy Information Administration FAQs:

"In 2016, world total primary energy consumption was about 572.8 quadrillion British thermal units (Btu). U.S. primary consumption was about 97.5 quadrillion Btu, equal to 17% of world total primary energy consumption."
