00:01What does it happen?
00:03It rains a lot and very quickly, in very little time.
00:06And it usually is a desencadenante of those risks or risks
00:09in an immediate period of time,
00:12after that rains, three or four days.
00:17It has a series of factors that are condicionated
00:20the structure of that material,
00:22the terrain,
00:22the terrain.
00:23Here in Canarias we have a very, very scarper
00:26that favorece the gravedad of rocks.
00:30Then, the vegetation,
00:31which sujet the terrain,
00:33but it increases the size of the roots
00:35and increases the size of the trees.
00:37And then there are a series of factors that are desencadenantes.
00:41And then the climate,
00:42the precipitation,
00:43the event sísmical
00:45and the anthropological factor.
00:46The construction or certain uses
00:48can favorece these situations of risk.
00:54We can protect ourselves knowing.
00:57That is what has allowed AGEO to put that knowledge
01:00close to the citizens
01:01and that they are capable
01:03of generating knowledge.
01:06That is something a bit difficult.
01:09What is the hoje?
01:11Movement gravitational,
01:13fog,
01:15precipitation,
01:16accumulation,
01:17such types of concepts
01:18that in a student class
01:20are simply words
01:21are capable of seeing them in reality.
01:23That is what has allowed AGEO to provide
01:25to them directly
01:26to the elements that generate
01:28the danger and the risk
01:30and they can see them
01:31and make them identify and apply it.
