This over time forms a <a href=\"https:\/\/en.wikipedia.org\/wiki\/Rift_valley\" target=\"_blank\">rift valley<\/a> (like \u00deingvellir). The area from Hveravellir and south into the ocean of the Reykjanes ridge is all just one big rift valley. Far as I know a period of high earthquake activity can happen in this area, last time this happened sometimes around the middle of 19th century with possible activity sometimes in the 20th (early) century. Since then it has been mostly quiet.<\/p>\n<p>In the year 1789 (<a href=\"http:\/\/timarit.is\/view_page_init.jsp?pageId=4271251\" target=\"_blank\">source<\/a> in Icelandic, 1973) the area around \u00deingvallavatn lake dropped around 63 cm (that estimate is not accurate and it is estimated that it was far more) in a earthquake swarm. When this is going to happen next time is impossible to know.<\/p>\n<p><strong>Donations<\/strong><\/p>\n<p>Please remember to support my work with donations.
