Vietnam

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...

  Vietnam's Seismic Acitivy On the case of earthquakes and where they are located the country of Vietnam shown on a seismic map provided by Think hazard shows Vietnam to be a medium hazard country. With the country being a medium hazardous place it means that there is a 10% chance of destructive earthquakes to hit the country in the next 50 years. The percentage is not high since as said in the previous post Vietnam's closest plate is the Eurasian plate which isn't that close to the country which is probably why the country doesn't face such intense Earthquakes. In the light orange spots the country faces low hazard quaked while the darker orange spots face medium hazard quakes. For the majority Vietnam faces around 12 earthquakes yearly with them having a magnitude of 4 with a few above that magnitude. Also in the past 10 years the strongest one Vietnam had is one with the magnitude of 6.2.  What the country does in the case of such disasters like quakes to prepare the...

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 ...
