why are areas where tectonic plates meet more dangerous than other areas?

Question

please answer in as much detail as possible but ty and keep it relatively simple if possible! thnx

Answer 1

Because the plates are still moving, ever so slowly. they're either moving toward each other, away from each other, or sideways to each other. The edges are ragged and catch on each other, plus there's friction, so the movement is not constant on the surface. So stress builds up around the edges because their movement is lagging behind that of the rest of the plate. Then it builds up too much and - bam!- the juts that have been catching on the next plate give way and the edge catches up with the rest of the plate all at once. We have an earthquake. That's what causes the earthquakes in California.

In Hawaii, two plates are moving away from each other. This creates a weak spot in the crust where molted lava can come to the surface. It hardens into rock. That's what formed the islands. The active volcano is still erupting, albeit in a more or less steady stream (not explosively like Mt. St. Helens and Mt. Pinatubo did). The lava just flows to the ocean and creates more land. Recently, though, a new flow began or it changed direction (I don't know which), and it burned up several houses.

The Himalaya Mountains, the highest in the world, were formed when two plates crashed into each other. The edges crumpled and formed the mountains. I would hate to have lived there then!

Answer 2

I assume you mean vertically, every several years along a faultline these tectonic plates shift. usually only inches in adjustment. Some of these are not noticble some of these are the ones that are really noticble we feel and register on the richter scale Graph. They have one at the LA Observatory you can jump up and down an make the needle extrude a little ink.

Since the adjustment of the tectonic plates are inches theses register as what we knowa s earthquakes anything in the 7.0 as being very strong on on down any strong quakes usually have aftershocks which register not as strong after the Quake. and usually are shorter and less intense than the quake itself.as the tectonic plates finish settling into their new adjustment position to reawaken in the future. As it may take years and years, But know faultlines are know because of a pattern of earthquakes and are often monitored in populated areas to record their strength and frequency

But the faultline areas where the tectonic plates meet are more dangerous( to answer your question) because even with good construction an earthquake reinforcment, Structures that are normally static and harmless around you can give way and potentially harm you critcally OR fatally,

AS EVEN THE UNPREPARED an heart coul kill you as In two scenarios One Big Los angeles Earthquake soo many like Seven people died of heart attacks.

Then two student at a College campus were crushe by a cement wall in a Parking structure A lot of people moved after the last bigone, a hurricane or a storm you can prepare for earthquake your warning is nonexistent, some people dont like or cant take surprises

Answer 3

Increased risk of the following:

Tsunami - that's what happened in 2004 in Sumatra - large shift in plates under the ocean caused a tsunami that swept through the Indian Ocean

Earthquakes - that's what happened in Northridge, California in 1994

Volcanos - that's what happened with Mount St. Helens in 1980.

All of these events occurred near the tectonic plate boundaries even if the results spread (like the Sumatra undersea quake) far from the source.

This happens because tectonic plates are moving and that movement causes friction and heat. Those forces build up and create volcanoes and earthquakes as a way to release heat and stress.

Answer 4

The places where tectonic plate meet are constantly moving.eventhough this is slow it often causes earth quakes in that region.
