Prediction, Forecasting, and Warning

Question 1

Probability that an event will occur based on
scientific observation

Answer 1

Prediction

Question 2

An anomalous small physical change that may be known to lead to a more devastating event.

Answer 2

Monitoring precursor events

Question 3

Prediction of floods, hurricanes, and other weather
related phenomena the word forecast refers to short term prediction in terms of the magnitude, location, date, and time of an event

Answer 3

Forecast

Question 4

Please read!
Prediction of earthquakes, the word forecast is used in a much less precise way referring to a long term probability that is not specific in terms of the exact time that the event will occur For example Prior to the October 17 1989 Loma Prieta Earthquake (also know as the World Series Earthquake) the U S Geological Survey had forecast a 50 probability that a large earthquake would occur in this area within the next 30 years Even after the event, the current forecast is for a 67 probability that a major earthquake will occur in this area in the next 30 years

Answer 4

Go go go

Question 5

Statement that a high probability of a hazardous event will occur, based on a prediction or forecast

Answer 5

Warning

Question 6

Answer 6

Red warning/Lumikas

Question 7

Matindi ang pag-ulan sa loob ng 1 oras at susunod pang 2 oras.

Answer 7

Orange warning/Alerto

Question 8

Malakas ang pag-ulan sa loob ng 1 oras at susunod pang 2 oras.

Answer 8

Yellow warning/Monitor

Question 9

The effectiveness of a warning depends on:

Answer 9

The timeliness of the warning

Effective communications and public information systems to
inform the public of the imminent danger and

The credibility of the sources from which the warning came

Question 10

It is the transition zone between upper & lower crust

Answer 10

Conrad Discontinuity

Question 11

Discontinuity between lower crust & upper mantle

Answer 11

Mohorovicic

Question 12

Answer 12

Repetti

Question 13

Discontinuity between lower mantle outer core

Answer 13

gutenberg

Question 14

Answer 14

lehman

Question 15

Composed largely of dark colored, mafic rocks enriched in oxides of magnesium, iron and calcium ( FeO and CaO relative to average crust

Answer 15

Oceanic crust

Question 16

Thickness of oceanic islands crust.

Answer 16

18 km

Question 17

Oceanic rocks such as ______ and ______.

Answer 17

basalt and gabbro

Question 18

Slices of ocean crust thrust onto continental margins

Answer 18

Ophiolites

Question 19

The formation of oceanic crust along the ridge axis generates layer 2 pillow basalts and dikes, layer 3 gabbros of the oceanic crust and layer 4 mantle peridotites. Sediment deposition on top of these rocks produces layer 1 of the crust. Sea floor spreading carries these laterally away from the ridge axis in both directions.

Answer 19

hallo

Question 20

Granitic in composition, enriched in K 2 O, Na 2 O and SiO 2

Answer 20

Continental crust

Question 21

Question 22

It is a mantle convection model which
suggests that cold oceanic lithosphere sinks to great
depths and stirs the entire mantle

Answer 22

Whole mantle convection model
