The Big One will be a great earthquake. An earthquake is the shaking of the ground cause by seismic waves. Almost all earthquakes occur when pent up stress in rocks along large, active faults (like the SAF) is suddenly released as the rock breaks.he Big One will be a great earthquake.

Iron is a magnetic substance, which means it is attracted by a magnet. On the other hand, Sulfur is a non-magnetic substance. If you place a magnet near a mixture of Iron and â¦ Sulfur, the iron pieces will stick to the magnet, while the sulfur powder will remain.
This will allow for ECAs to specify limits not just for sulphur oxides (SOx), but also for particulate matter (PM), and (NOx). Marpol annex VI in force from May 19 2005 limits the maximum sulphur content of fuel to 4.5%. This changes to 3.5% after 1st Jan 2012 and to 0.5% after 2020 (or 2025, depending on the outcome of a review in 2018.).
