Solid iron, with impurities of other heavy metals

Because the earthquake made 156 casualties due to landslides.

The earth's inner core is solid composed of nickel iron alloy. It is solid despite the very high temperature because of the very high pressure.

Yes, and using what was known about the earth at that time Wegener's continental drift theory was so implausible that it had to be rejected.

It took data secretly collected by the US Navy after WW2 to account for strange magnetic anomalies that interfered with precision navigation of warships and submarines to give the first hints of a plausible mechanism. But since this data was classified for a long time it was not available to the scientific community, long delaying acceptance of the theory. When the theory was finally accepted the name had been changed to plate tectonics, because it wasn't the continents drifting it was the plates shifting (both continental and oceanic).

The Nazca plate shares both convergent and divergent boundaries. The Pacific plate has both a transform boundary and divergent boundary

"Seismic" refers to an earthquake, so seismic shaking is the shaking motion of the earth (and things on it) caused by an earthquake. There are different waves that emanate from the hypocenter, or point of origin.

Nearby topography (hills and valleys) attracts the mass in the gravimeter (valleys are considered to have negative density with respect to the surrounding rocks) and reduces the observed value of gravity. The terrain correction is the calculated effect of this topography and is always positive (a hill pulls up on the mass in the gravimeter and a valley is a mass deficiency).

The India plate crashing into the Asia plate caused the formation of the Himalayas. It can also cause subduction, when one plate is pushed beneath the other plate and so pushed back into the molten mantle.

the speed of the earths plates are very slow, and sometimes they don't move at all. if the earths plates were constantly moving (allot) then we would not be able to build cities because of constant earthquakes.

Two things that supports the continental drift theory are;

1. Fossil.

2. Continent Shapes.

Plants absrb water through their roots which are in soil; so there must be water under the soil for the plants to survive.

False. An earthquake is a seismic wave caused by a sudden release of energy.

The Earth's magnetic field is the result of electric currents in the liquid metal outer core.

The outer core of the Earth is over 2,000 km thick. It sits above the solid inner core and is composed of highly conducting liquid iron and nickel. Above the outer core is the Earth's mantle.

The geodynamo is the mechanism thought to be responsible for the generation of the Earth's magnetic field through the convection of conducting fluids in the Earth's core. Other planets with a molten metal core can also have a magnetic field.

Why not look into the use of current gps technology, and see if it is accurate enough to measure continental drift over short periods of time? Maybe this method is uncovering data that seems to be at odds with the current theory.

Maybe you could look at projected movements and see if the projections help you predict future hot spots, like the currently well know circle of fire.

yes florida has sinkholes as 1 of maste wastin but gulf i dk if it does or not.

According to the US Geological survey the Haitian Earthquake had the capacity to cause some minor structural damage to buildings as far away as 300 km from the Earthquakes epicentre (level V or 5 on the Modified Mercalli Intensity scale.

It was felt by humans as far away as Guantanamo in Cuba (level III or 3 on the Modified Mercalli Intensity scale) and would most likely have been detected by seismometers all over the world.

Please see the related question and link.

A seismic monitor is a device used to measure and record ground motion and seismic activity such as earthquakes. It typically consists of sensors that detect vibrations and convert them into electrical signals, which are then analyzed to provide valuable data about the occurrence and characteristics of seismic events.

gravity and movement

The earthquake of magnitude 7.6 claimed more than 80,000 lives

3, or that's what i remember from science class.

If the primary stiffners of the hull is in transverse direction, that design is called transverse framing. and If the primary stiffners of the hull is in longitudinal direction, that is called longitudinally framed ship
