#AsíSeVe la microcuenca del norte de #LasTejerías (que incluye las quebradas de Patos y #Chorrerón) cuyo desbordamiento y #deslave el sábado 8OCT causó severos daños a la pequeña ciudad y dejó múltiples víctimas por el colapso de viviendas y demás inmuebles.
Las imágenes fueron obtenidas en un vuelo de helicóptero del servicio aéreo de la Gobernación de Aragua. (Video)
Hemos hecho diversas capturas "cuadro a cuadro" para observar desplazamientos importantes de masas de tierra y deslizamiento/destrucción de la capa vegetal. ImageImageImageImage
Se nota que el descenso del agua provocó profundas cicatrices verticales desde puntos elevados.
El cauce se ve ocupado por una masa de barro que evidentemente estuvo en movimiento durante la lluvia y permite suponer que se registró un flujo de detritus o escombros (#debrisflow). ImageImageImageImage
