Volcanologists use many different kinds of tools including instruments that detect and record earthquakes (seismometers and seismographs) instruments that measure ground deformation (EDM, Leveling, GPS, tilt),instruments that detect and measure volcanic gases (COSPEC),instruments that determine how much lava is moving underground (VLF, EM-31), video and still cameras, infrared cameras and cameras that work remotely. This is by no means a complete list, volcanologists will use whatever tool they can to help them understand volcanoes.

The most common would be seismographs and seismometers, which measure any type of movement in the Earth's crust (including volcanic eruptions). Volcanologists also use special instruments to measure volcanic gases (COSPEC), instruments that determine how the lava moves under ground, and a variety of cameras, GPS devices, and satellite imaging devices.
Seismographs(or whatever they're called) measure any tremors or earthquakes made by the volcano or other geological activity in origin; satellites to measure the rise & fall of the land caused by the volcano's activity/magma chamber, record the eruption/ash cloud plume that drifts away from the volcano/etc, news video camera recorders, etc.
You don't. Mankind is not able to affect any aspect of a volcano, other than to monitor when it may erupt. That includes magma/ lava.
this all has to do with where the volcano is located. some volcanos are located in places where ther is more activity underneath, and other have not so much activity. the more activity, the more violently the volcano will erupt.
If the volcano is currently active, sometimes you can, but that is certainly not a tourist activity. Vulcanologists - who willingly put themselves at more risk than people in almost any other profession - do it commonly, though.
Right now Mount St Helens is dormant.
earthquake and volcano activity zones are located where tectonic plates meet and either converge diverge or slide past each other.
The works of a volcanologist mainly entail studying volcanoes and other related activities. They concentrate with the activities in the lithosphere.
To monitor account activity it is the simple task of remembering passwords, as well as checking the account regularly for updates. This can also be done via other venues of checking such as a tablet or a cell phone text message.

People who service Routers, Switches, and any other networking device. they monitor the activity of there network and make sure it functions correctly.
You can do this to monitor the activity on the other computer or just connect them for easier use together for things like the internet.

The more experienced a volcanologist the more they earn. Try this site: http://volcano.und.edu/vwdocs/frequent_questions/grp13/new/6.html (It shows the salaries of volcanologists as their experience increases. Also other info on volcanologists.)
Los Angeles is on a seismic fault so anything is possible, but since there is no other volcanic activity nearby it is unlikely.
The Holter monitor is a device attached to the body to monitor heart activity. It is worn for a period of time and records and monitors the heart for abnormal rhythms as well as other cardiac disorders. The long period of time helps find problems that a shorter test may not pick up.
