the most earthquakiest earthquakes and volcaniest volcanoes by Alexander Macias

how earthquakes happen

alexanderem0105 — 2015-03-19 18:16:25 UTC

as you can see from this diagram there is a focal point that causes the seismic waves to originate from and cause anything on the surface to shake and collapse

Earthquake formations

2015-03-23 18:14:28 UTC

Earthquakes form when two plates are moving in opposing directions and enough pressure is applied by these plates that when they move they cause a tremor that shakes anything above where these plates moved the point that this happens at is the focal point which is the origin of the earthquake

Earthquake examples

alexanderem0105 — 2015-03-23 18:27:50 UTC

These are all examples of different types of earthquakes

nice so far.

s wave

alexanderem0105 — 2015-03-24 17:47:43 UTC

seismic body wave that shakes the ground perpindicular to the directiuon the wave is moving

p wave

alexanderem0105 — 2015-03-24 17:50:56 UTC

these cause other rocks to change in volume when this wave passes through they are also alternatingly compressioal and extensional. these waves are the fastest seismic waves and they can pass through solids, liquids, and gases

when an earthquake occurs undewater

alexanderem0105 — 2015-03-24 18:00:25 UTC

these are called tsunamis and sometimes occur underwater of course this is due to a convergent boundary which causes one plate sub duct under another

p and s waves

alexanderem0105 — 2015-03-24 18:08:20 UTC

this is what p and s waves look like

Great job with your page. Continue to work.

epicenter

alexanderem0105 — 2015-03-24 18:15:51 UTC

this is the point on earths surface that is directly above the focal point of an earthquake

tectonic plates

alexanderem0105 — 2015-03-24 18:18:25 UTC

these are giant pieces of the earths outermost layer that move around on top of a layer of plastic rock

volcanic earthquake

alexanderem0105 — 2015-03-31 18:02:54 UTC

this is an earthquake that is induced by the movement of magma. the movement results in pressure changes in the rock around where the magma has experienced stress. at some point the rock may break or move

aftershock

alexanderem0105 — 2015-03-31 18:08:18 UTC

a smaller earthquake following the main shock of a large earthquake

composite volcanoe

alexanderem0105 — 2015-04-01 17:43:33 UTC

a conical volcano that is built up of many layers of hardened lava, tephra, pumice, volcanic ash

shield volcano

alexanderem0105 — 2015-04-01 17:45:57 UTC

a broad, domed volcano with gently sloping slides, characteristic of the eruption of fluid, basaltic lava

cinder volcano

alexanderem0105 — 2015-04-01 17:55:01 UTC

steep, conical hill consisting of glassy volcanic fragments that accumulate around and downwind from a volcanic vent. range in sizes from tens to thousands of meters.

ring of fire

alexanderem0105 — 2015-04-01 17:58:28 UTC

an area where multiple earthquakes and volcanic eruptions occur in the basin of the pacific ocean

paleozoic era

alexanderem0105 — 2015-04-01 18:02:00 UTC

spans almost 200 million years from 542 to 251 million years ago. it is the oldest and longest era of the Phanerozoic eon. this is when many plants dominated the earth and there were only early micro organisms because life had just begun and there was only plants and water. three organisms that lived during this era were trilobites, brachiopods, and archaeocyathids

mesozoic era

alexanderem0105 — 2015-04-01 18:13:11 UTC

tome from 248 million to 65 million years ago. during this time the earths climate was warmer, the seasons were very mild, the sea level was higher, and there were no polar ice caps. this is also when Pangea was formed and all of the continents had different shapes than they do now. this was the birth of dinosaurs such as the rapotr, tryannosaurus rex, and stegosaurus

different parts of the volcano

alexanderem0105 — 2015-04-01 18:19:08 UTC

magma-molten rock beneath earths surface

parasitic cone-small cone shaped volcano formed by an accumulation of volcanic debris

sill-flat piece of rock formed when magma hardens in a crack in a volcano

vent-an opening in earths surface through which volcanic materials escape

flank-side of the volcano

lava-molten rock that erupts from a volcano that solidifies as it cool

crater-mouth of volcano-surrounds a volcanic vent

conduit-an underground passage that magma travels through

summit-highest point;apex

throat-entrance of a volcano.that part of the conduit that ejects lava and volcanic ash

ash-fragments of lava or rock smaller than 2 mm in size that are blasted into the air by volcanic explosion

ash cloud-cloud of ash formed by volcanic explosions

cenozoic era

alexanderem0105 — 2015-04-01 18:21:11 UTC

present era beginning 65 million years ago and characterized by the ascendance of mammals. this is the time period of when man began. this is also when the continents split apart and mammals roamed the earth. such as the rhinoceros, elephant, and dogs and cats.

Mount St. Helens is an active stratovolcano located in Skamania County, Washington, in the Pacific Northwest region of the United States

warning!

prepare for some new knowledge on volcanoes and earthquakes when you read this page you will blow up from the amount of truth that is in this if you see an error with any of my posts please leave a comment and i will fix it if you don't like my page then you will just have to go deal with the fact that your butt-hurt and maybe need to look yourself in the mirror and say "I'm a loser" and shout that i'm right and your wrong cause when it comes to this i'm always right and you can go deal with it!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

ya i said it.

a current earthquake that happened about 18 hours ago was an earthquake located in eureka, Nevada with the magnitude of 2.8. scientists found the magnitude of this earthquake by reading the seismograph readings.no information about this earthquake has been put on TV and the focus and epicenter have not yet been found and fault lines did not effect this earthquake in any way
