Lanzamiento del Proyecto DIPECHO PLAN-CARE

El IG-EPN asistió al evento de lanzamiento del Proyecto DIPECHO 2018-2019 ejecutado entre PLAN International y CARE en los cantones de Latacunga, Pujilí y Saquisilí (provincia de Cotopaxi) y Manta y Pedernales (provincia de Manabí). Este evento se realizó en la ciudad de Latacunga el martes 31 de Julio a las 10h00 en el Auditorio de la Gobernación de Cotopaxi.

Estuvieron presentes el perfecto de la provincia de Cotopaxi el Ing. Jorge Guamán, representantes de los GADS cantonales de Cotopaxi y de los dos cantones de Manabí (Manta y Pedernales), la Gobernación de Cotopaxi y la Zonal 3 de la Secretaría de Gestión de Riesgos
Por su amplia trayectoria en vigilancia volcánica y sísmica, el Instituto Geofísico de la Escuela Politécnica Nacional va a dar el apoyo técnico para brindar los insumos sobre las amenazas volcánicas y sísmicas.

El Taller 2018 Científico Bianual de UNAVCO fue llevado a cabo en Broomfield Colorado en las afueras de Denver, USA, entre el 26 y 29 de marzo de 2018.   Tuvo como objetivo promocionar la geodesia en geociencias y sus aplicaciones hacia la sociedad.  Se trató diversos temas como cambios en los niveles del mar, controles de masa de hielo en las zonas polares, la atmósfera y sus cambios, nuevas metodologías de geodesia para el estudio del monitoreo de volcanes con GPS, InSAR, modelamiento de los datos y la aplicación de geodesia al estudio de zonas de subducción.  El evento fue realizado con el auspicio de la NSF (National Science Foundation) de los Estados Unidos.

Se hizo énfasis de forma particular en los estudios que emplean tecnología GPS en tiempo cuasi-real para la detección de tsunamis, uso de InSAR y de nuevas constelaciones de satélites, además de la práctica de geodesia en el fondo del océano en zonas de subducción.

Entre el 4 y el 22 de diciembre del 2017, el Museo de Historia Natural “Gustavo Ocres V.” y el Instituto Geofísico de la Escuela Politécnica Nacional homenajearon a las Montañas con una serie de exposiciones. Algunas instituciones visitaron el Centro Terras del Instituto Geofísico en donde se explicó las diferentes labores de monitoreo de la actividad sísmica y volcánica, y los instrumentos que se utilizan en todo el Ecuador. Por otro lado, el recorrido en el museo de Historia Natural consistió de varias paradas en las que se compartió las teorías del origen del universo, las galaxias y planetas, la estructura interna de la Tierra, la teoría de la tectónica de Placas, la importancia de la geología para el entendimiento de los fenómenos naturales que ocurrieron hace cientos de millones de años y los fenómenos sísmicos y volcánicos.

Más de 300 visitantes en el Museo de Historia Natural de la EPN por el Día Internacional de las Montañas
