 There are a total of 5 volcanoes in the Netherlands, although most are inactive. The two volcanoes that are active are located in the Caribbean territories that belong to the Netherlands. “The Quill," a stratovolcano with a 760-m-wide crater, on St. Eustatius last erupted in 250 CE, and is estimated to have formed about 32,000 - 22,000 years ago. “Saba,” the north-most active volcano of the Netherland’s West Indies territory, last erupted in 1650 CE. According to De Zeeuw, chances of an eruption (from these volcanoes) in the near future are small, but if it does happen the consequences could be disastrous. The Quill Saba Nearer to the Netherlands are the volcanoes Mulciber and Zuidwal, which are both now extinct. Zuidwal was discovered in 1970, just off the coast of the Netherlands. In 2020, Mulciber was found 100 kilometers northwest of Texel through geologic data collected from the North Sea. Aged 150 million years, Mulciber was formerly active during the breakup of Pangea.

 Hello everyone! As I mentioned last week, there is a region to the southwest of the Netherlands that has notable earthquake activity, which I thought may affect the country on a smaller scale. However, according to ThinkHazard.org, earthquake hazards are classified as a medium-level concern in the Netherlands. As seen in the map below, earthquakes are most prevalent in the southeastern regions of the Netherlands. The Royal Netherlands Meteorological Institute (also known as KNMI) has been measuring the country’s earthquakes since 1904. The strongest earthquake KNMI has on record dates back to April 13 of 1992 and measured 5.8 on the Richter scale. The epicenter was located several kilometers southwest of Roermond, which experienced significant damage, along with Maaseik and Heinsberg. The total damage was estimated to have cost the Netherlands 275 million guilders (approx. $150 million USD). This earthquake was also felt in the Czech Republic, Switzerland, France and England. At t...

 Hello everyone! Using the map provided by the NOAA, I found that the Netherlands is located on the Eurasian plate. The Netherlands are a fair distance away from the more active convergent and transforming plate boundaries near Africa, so it is highly unlikely that the Netherlands would have any volcanic activity. However, according to the map, a region to the southwest of the Netherlands has notable earthquake activity. It may be possible that these earthquakes affect the Netherlands on a smaller scale.
