you would use a weather satellite or doppler radar.
It is given its name before in even becomes a hurricane. Storms are named when they reach tropical storm status. Roughly half of all tropical storms become hurricanes.
Yes, every year has a list of names that will be assigned to storms in alphabetical order as they reach tropical storm intensity (for example the first in 2010 was Hurricane Alex followed by Tropical Storm Bonnie etc.). Each list of names is re-used every six years except for names of storms that are especially bad such as Andrew and Katrina.
A tropical cyclone is given a name when it reaches tropical storm status, with winds of at least 39 mph. Each year has a list of 21 names for tropical cyclones. These names are in alphabetical order and alternated in gender. The letters Q, U, X, Y, and Z are not used as there are not enough names that start with these letters. As an example, the first four this year tropical storms and hurricanes were Alex, Bonnie, Colin, and Danielle. Normally names are re-used every six years unless a storm is particularly bad, in which case the name is retired and replaced.
No. Names are only given to to as many storms that reach tropical storm strength. On average about 10 of the 21 available names get used in a season. There is list of 21 names for these letters of the alphabet: A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,R,S,T,V,W. The names alternate between boy and girl names and are made up 6 years in advance by the committee of the World Meteorological Organization. This list is set barring any last minutes changes due to retired names because of infamous damage or lost of life. Once a tropical depression reaches 39 mph then it officially becomes a tropical storm and is assigned the next unused name on that year's list starting with the A name. So if there is not enough storms in that year reaching that level then the remaining names are just not used. However in the unlikely event that there are more than 21 storms then the Greek alphabet is used to finish the list and these can not be retired. In 2005 there was 27 named storms which included Alpha, Beta, Gamma, Delta, Epsilon and Zeta.
A seismograph is used to detect earthquakes.
flux meter
Smoke detectors are devices that detect smoke. They are used as warning devices in houses to warn people of fire.
The letters Q, U, X, Y, and Z are not used.
Laser-ranging devices us laser beams to detect the fault movements that cause earthquakes.
krypton
No, these devices do not cause cancer or they would not be used in hospitals. They can detect cancer and are also used on pregnancy so they do not cause cancer!

A wave meter tube is a tubular device used to detect wave signals from electronic devices. It can be used to detect microwaves, and waves emitted from televisions.
Different devices are used to detect different frequency ranges of electromagnetic waves. You simply can't use the same device to detect x-rays, than you would use to detect radio waves, for example.
Voltmeter. PowerProbe. Testlight.
Seismographs and fault-monitoring devices provide data used to map faults and detect changes along faults.
