Northern Mariana Islands History

The Northern Mariana Islands, together with Guam to the south, compose the Mariana Islands.

The southern islands are limestone with level terraces and fringing coral reefs; the northern islands are volcanic, with active volcanoes on Anatahan, Pagan and Agrihan. The volcano on Agrihan has the highest elevation in the islands at 3,166 feet. About one-fifth of the land is arable, another tenth is pasture. The primary natural resource is fish, some of which are endangered species, which leads to conflict. Also, development has created landfills which have contaminated groundwater on Saipan, which might contribute to disease.

Anatahan Volcano is a small volcanic island 80 miles north of Saipan and is about 6 miles long and 2 miles wide. Anatahan began erupting suddenly from its east crater on May 10, 2003, at about 6 p.m.. Since then it has continued to alternate between eruptive and calm periods. On April 6, 2005, approximately 50,000 cubic meters of ash and rock were ejected, causing a large, black cloud to drift south over Saipan and Tinian.

The islands have a tropical marine climate moderated by seasonal northeast trade winds. There is little seasonal temperature variation; the dry season runs from December to June, and the rainy season from July to November and can include typhoons. The Guinness Book of World Records has cited Saipan as having the most equable temperature in the world.
