Volcanoes

Volcanic Activity

The country of Vietnam does have volcanoes with 2 being Holocene and 9 of them being Pleistocene. Even though the country may have volcanoes its hazard risk is actually very low since there has been no report about an eruption happening in recent years. The last eruption to happen in Vietnam  was due to the Iles des Cendres volcano which erupted on March 2 1923 CE and lasted up till May 13 1923 CE with a VEI of 2. The rock type of this last volcanic eruption consisted of Basalt/Picro-Basalt rocks and location of the volcano was on the Intraplate as well as it being (>25km) of the continental crust.  Not only that but the Iles des Cendres is actually a group of submarine volcanoes that are located on the South East coast of Vietnam and the volcanoes responsible for the eruption in 1923 CE where two submarine lava cones which during the eruption made ephemeral islands. Even though there hasn't been volcanic activity in years and the country is at low risk of having an eruption I still believe that there should be a plane made in case because one can never know. Currently my country has no mitigation plans in case of a volcanic eruption but some things they can do in this situation is to move machinery and vehicles under something or cover them with tarps if ash is forecasted to fall. The main thing would also be to stay indoors when ash is falling and to close all windows/entrances to one's home. On the other hand where ever volcanos are located in the country the country can create an evacuation plan for the neighboring cities near those volcanoes and make hazard zone maps.

    Hi Erica! Great blog post. That is insane that Vietnam has volcanoes but still no plan in place for when there is an eruption. It is also very neat that your country has submarine lava cones! Rwanda couldn't be more different: there is an agency put into place to handle all of the natural disasters that Rwanda may face and they also have a revamped Red Cross prepared for emergencies. Vietnam should think twice!

    Hello Erica, I think it is so interesting how volcanoes have happened so far back in history and how there is a low threat of them happening now. It makes you wonder if there is an earthquake or some other earth shaking event, if it could wake up those sleeping volcanoes. I think that there should be volcano procedures in place just in case. Like you said, you never know. Thanks for the blog..

Tectonic Plate Boundaries

Surrounding Plates The closest plate located near Vietnam is the Eurasian Plate. Not only that but below the country the Indo-Australian Plate lies there not too far from Vietnam but also not too close. As for the Northern part of Vietnam it is on the Sudan Plate as most of Southeast Asia is. From what I found in my research is that Vietnam has divergent as well as convergent-collision boundaries. What this means is that for divergent it is mostly focused on earthquakes which Vietnam experiences low to medium amounts of quakes. These earthquakes that happen in the country don't go higher than a magnitude of 5 and the biggest earthquake that the country has experienced was in Dien Bien in 1935 and one in 1983 that ranged from a magnitude of between 6 to 7. As for convergent-collision boundaries it ties in with the country since Vietnam mostly experiences floods and typhoons which destroys crops and affects people due to the destruction of homes. These large events happen because of ...

Final Hazard Report

Image
Vietnam's Hazard Report      After researching on the country of Vietnam and learning about the many hazards the country experiences there are a few key hazards that are considered as the most hazardous. These very hazards consist of coastal erosion and landslides. The reason for choosing these two specific hazards is due to the fact that other hazards take a part in these two hazards happening often. The main reason for landslides happening continuously is because of certain places like mountainous regions getting heavy rainfall that lasts for weeks which weakens the sediment. As for coastal erosion it happens due to the constant crashing of waves as well as tropical cyclones which consist of 60% of Vietnam's storms which affect the marine zone. These two events are also the reason why many people lose their lives throughout the years.      Not only that but the reason why the country experiences such things in general is due to the location of the country...
