Question: Where is the new island forming in the state that voluntarily joined the US as a colony in 1898?

full_context: Document 1: History of Puerto Rico: Located in the northeastern Caribbean, Puerto Rico formed a key part of the Spanish Empire from the early years of the exploration, conquest and colonization of the New World. The island was a major military post during many wars between Spain and other European powers for control of the region in the 16th, 17th and 18th centuries. The smallest of the Greater Antilles, Puerto Rico was a stepping - stone in the passage from Europe to Cuba, Mexico, Central America, and the northern territories of South America. Throughout most of the 19th century until the conclusion of the Spanish -- American War, Puerto Rico and Cuba were the last two Spanish colonies in the New World; they served as Spain's final outposts in a strategy to regain control of the American continents. Realizing that it was in danger of losing its two remaining Caribbean territories, the Spanish Crown revived the Royal Decree of Graces of 1815. The decree was printed in Spanish, English and French in order to attract Europeans, with the hope that the independence movements would lose their popularity and strength with the arrival of new settlers. Free land was offered to those who wanted to populate the islands on the condition that they swear their loyalty to the Spanish Crown and allegiance to the Roman Catholic Church.
Document 2: Republic of Cuba (1902–1959): After the Spanish -- American War, Spain and the United States signed the Treaty of Paris (1898), by which Spain ceded Puerto Rico, the Philippines, and Guam to the United States for the sum of $20 million. Cuba gained formal independence from the U.S. on May 20, 1902, as the Republic of Cuba. Under Cuba's new constitution, the U.S. retained the right to intervene in Cuban affairs and to supervise its finances and foreign relations. Under the Platt Amendment, the U.S. leased the Guantánamo Bay naval base from Cuba.
Document 3: Latin America–United States relations: As unrest in Cuba escalated in the 1890s, the United States demanded reforms that Spain was unable to accomplish. The result was the short Spanish -- American War of 1898, in which United States acquired Puerto Rico and set up a protectorate over Cuba under the Platt Amendment rule passed as part of the 1901 Army Appropriations Bill. The building of the Panama Canal absorbed American attention from 1903. The US facilitated a revolt that made Panama independent and set up the Panama Canal Zone as an American owned and operated district that was finally returned to Panama in 1979. The Canal opened in 1914 and proved a major factor in world trade. The United States paid special attention to protection of the military approaches to the Panama Canal, including threats by Germany. Repeatedly it seized temporary control of several countries, especially Haiti and Nicaragua.
Document 4: Capture of Guam: The Capture of Guam was a bloodless event between the United States and the Kingdom of Spain during the Spanish -- American War. The U.S. Navy sent a single cruiser, the USS Charleston, to capture the island of Guam, then under Spanish control. However, the Spanish garrison on the island had no knowledge of the war and no real defenses. They surrendered without resistance and the island passed into American control. The event was the only conflict of the Spanish -- American War on Guam.
Document 5: Spanish–American War: The Spanish–American War (Spanish: Guerra hispano-americana or Guerra hispano-estadounidense; Filipino: Digmaang Espanyol-Amerikano) was an armed conflict between Spain and the United States in 1898. Hostilities began in the aftermath of the internal explosion of USS Maine in Havana harbor in Cuba, leading to U.S. intervention in the Cuban War of Independence. The war led to emergence of U.S. predominance in the Caribbean region, and resulted in U.S. acquisition of Spain's Pacific possessions. That led to U.S. involvement in the Philippine Revolution and ultimately in the Philippine–American War.The main issue was Cuban independence. Revolts had been occurring for some years in Cuba against Spanish rule. The U.S. later backed these revolts upon entering the Spanish–American War. There had been war scares before, as in the Virginius Affair in 1873, but in the late 1890s, American public opinion was agitated by reports of gruesome Spanish atrocities. The business community had just recovered from a deep depression and feared that a war would reverse the gains. It lobbied vigorously against going to war. President William McKinley ignored the exaggerated yellow press and sought a peaceful settlement. The United States Navy armored cruiser USS Maine mysteriously exploded and sank in Havana Harbor; political pressures from the Democratic Party pushed McKinley into a war that he had wished to avoid.
Document 6: Military history of the United States: The Spanish–American War was a short decisive war marked by quick, overwhelming American victories at sea and on land against Spain. The Navy was well-prepared and won laurels, even as politicians tried (and failed) to have it redeployed to defend East Coast cities against potential threats from the feeble Spanish fleet. The Army performed well in combat in Cuba. However, it was too oriented to small posts in the West and not as well-prepared for an overseas conflict. It relied on volunteers and state militia units, which faced logistical, training and food problems in the staging areas in Florida. The United States freed Cuba (after an occupation by the U.S. Army). By the peace treaty Spain ceded to the United States its colonies of Puerto Rico, Guam, and the Philippines. The Navy set up coaling stations there and in Hawaii (which voluntarily joined the U.S. in 1898). The U.S. Navy now had a major forward presence across the Pacific and (with the lease of Guantánamo Bay Naval Base in Cuba) a major base in the Caribbean guarding the approaches to the Gulf Coast and the Panama Canal.
Document 7: Hawaiʻi Volcanoes National Park: Hawai ʻi Volcanoes National Park, established on August 1, 1916, is an American National Park located in the U.S. state of Hawaii on the island of Hawaii. It encompasses two active volcanoes: Kīlauea, one of the world's most active volcanoes, and Mauna Loa, the world's most massive shield volcano. The park delivers scientists insight into the birth of the Hawaiian Islands and ongoing studies into the processes of volcanism. For visitors, the park offers dramatic volcanic landscapes as well as glimpses of rare flora and fauna.
Document 8: Wake Island: With the annexation of Hawaii in 1898 and the seizure of Guam and the Philippines during the Spanish -- American War that same year, the United States began to consider unclaimed and uninhabited Wake Island, located approximately halfway between Honolulu and Manila, as a good location for a telegraph cable station and coaling station for refueling warships of the rapidly expanding United States Navy and passing merchant and passenger steamships. On July 4, 1898, United States Army Brigadier General Francis V. Greene of the 2nd Brigade, Philippine Expeditionary Force, of the Eighth Army Corps, stopped at Wake Island and raised the American flag while en route to the Philippines on the steamship liner SS China.
Document 9: Ninole Hills: The Ninole Hills, also known as the Ninole Volcanic Series, are steep eroded hills of shield basalts on the south side of the Island of Hawaii. Recent data suggests that these hills are either the remnants of large escarpments that pre-date the Mauna Loa volcano (the largest active volcano in the world), or uplifted blocks from the oldest parts of the Mauna Loa fault system.
Document 10: Teide: If measured from the ocean floor, it is at 7,500 m (24,600 ft) the highest volcano in the world base - to - peak outside of the Hawaiian Islands, and is described by UNESCO and NASA as Earth's third - tallest volcanic structure. Teide's elevation makes Tenerife the tenth highest island in the world. Teide is an active volcano: its most recent eruption occurred in 1909 from the El Chinyero vent on the northwestern Santiago rift. The United Nations Committee for Disaster Mitigation designated Teide a Decade Volcano because of its history of destructive eruptions and its proximity to several large towns, of which the closest are Garachico, Icod de los Vinos and Puerto de la Cruz. Teide, Pico Viejo and Montaña Blanca form the Central Volcanic Complex of Tenerife.
Document 11: Lōʻihi Seamount: Lōihi Seamount (also known as Lōʻihi) is an active submarine volcano about 35 km (22 mi) off the southeast coast of the island of Hawaii. The top of the seamount is about 975 m (3,000 ft) below sea level. This seamount is on the flank of Mauna Loa, the largest shield volcano on Earth. Lōihi, meaning ``long ''in Hawaiian, is the newest volcano in the Hawaiian - Emperor seamount chain, a string of volcanoes that stretches over 5,800 km (3,600 mi) northwest of Lōʻihi. Unlike most active volcanoes in the Pacific Ocean that make up the active plate margins on the Pacific Ring of Fire, Lōʻihi and the other volcanoes of the Hawaiian - Emperor seamount chain are hotspot volcanoes and formed well away from the nearest plate boundary. Volcanoes in the Hawaiian Islands arise from the Hawaii hotspot, and as the youngest volcano in the chain, Lōihi is the only Hawaiian volcano in the deep submarine preshield stage of development.
Document 12: Samoa: The Samoan islands have been produced by vulcanism, the source of which is the Samoa hotspot which is probably the result of a mantle plume. While all of the islands have volcanic origins, only Savai'i, the western most island in Samoa, is volcanically active with the most recent eruptions in Mt Matavanu (1905–1911), Mata o le Afi (1902) and Mauga Afi (1725). The highest point in Samoa is Mt Silisili, at 1858 m (6,096 ft). The Saleaula lava fields situated on the central north coast of Savai'i are the result of the Mt Matavanu eruptions which left 50 km² (20 sq mi) of solidified lava.
Document 13: Guam: The United States took control of the island in the 1898 Spanish–American War, as part of the Treaty of Paris. Guam was transferred to U.S. Navy control on 23 December 1898 by Executive Order 108-A. Guam came to serve as a station for American ships traveling to and from the Philippines, while the Northern Mariana Islands passed to Germany, and then to Japan. A U.S. Navy yard was established at Piti in 1899, and a marine barracks at Sumay in 1901.:13 Following the Philippine–American War, Emilio Aguinaldo and Apolinario Mabini were exiled on Guam in 1901.:vi
Document 14: Geography of the United States: The West Coast of the continental United States and areas of Alaska (including the Aleutian Islands, the Alaskan Peninsula and southern Alaskan coast) make up part of the Pacific Ring of Fire, an area of heavy tectonic and volcanic activity that is the source of 90% of the world's earthquakes.[citation needed] The American Northwest sees the highest concentration of active volcanoes in the United States, in Washington, Oregon and northern California along the Cascade Mountains. There are several active volcanoes located in the islands of Hawaii, including Kilauea in ongoing eruption since 1983, but they do not typically adversely affect the inhabitants of the islands. There has not been a major life-threatening eruption on the Hawaiian islands since the 17th century. Volcanic eruptions can occasionally be devastating, such as in the 1980 eruption of Mount St. Helens in Washington.
Document 15: Alaska: With its myriad islands, Alaska has nearly 34,000 miles (54,720 km) of tidal shoreline. The Aleutian Islands chain extends west from the southern tip of the Alaska Peninsula. Many active volcanoes are found in the Aleutians and in coastal regions. Unimak Island, for example, is home to Mount Shishaldin, which is an occasionally smoldering volcano that rises to 10,000 feet (3,048 m) above the North Pacific. It is the most perfect volcanic cone on Earth, even more symmetrical than Japan's Mount Fuji. The chain of volcanoes extends to Mount Spurr, west of Anchorage on the mainland. Geologists have identified Alaska as part of Wrangellia, a large region consisting of multiple states and Canadian provinces in the Pacific Northwest, which is actively undergoing continent building.
