Geological Summary

The triangular-shaped Easter Island, renowned for its dramatic megalithic statues of hand-carved basalt, sits atop the Sala y Gomez submarine ridge, which trends eastward from the East Pacific Rise. Easter Island, also known as Isla de Pascua or Rapa Nui, forms the westernmost territory of Chile. The island is composed of three principal volcanoes and more than 70 subsidiary vents. Rano Kau, which contains a flat-bottomed, 1-km-wide crater, and Poike volcano form the SW and east tips of the island, respectively, and are of Pleistocene age. The youngest and largest volcano, Terevaka, is a broad shield volcano of Pliocene-to-Pleistocene age at the northern leg of the triangular island, which is capped by many pyroclastic cones. The last stage of activity consisted of eruptions from multiple rift zones extending along the axes of the island and radially from them. The latest lava flows, at Hiva-Hiva near the west-central coast, are thought to be less than 2000 years old.

The Global Volcanism Program is not aware of any Holocene eruptions from Easter Island. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Easter Island page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

Waves lap against the northern coast of Easter island. This view looks from Obahe to Mahatua with Volcán Poike, a shield volcano forming the eastern tip of the island, on the horizon. The trachytic lava domes of Tea-Tea are the small peaks on the left horizon. The triangle-shaped Easter Island, renowned for its dramatic megalithic statues of hand-carved basalt, sits atop the Sala y Gómez submarine ridge, which trends eastward from the East Pacific Rise. The island is composed of three principal volcanoes, Poike, Rano Kau, and Terevaka.

MODVOLC - HIGP MODIS Thermal Alert System Using infrared satellite Moderate Resolution Imaging Spectroradiometer (MODIS) data, scientists at the Hawai'i Institute of Geophysics and Planetology, University of Hawai'i, developed an automated system called MODVOLC to map thermal hot-spots in near real time. For each MODIS image, the algorithm automatically scans each 1 km pixel within it to check for high-temperature hot-spots. When one is found the date, time, location, and intensity are recorded. MODIS looks at every square km of the Earth every 48 hours, once during the day and once during the night, and the presence of two MODIS sensors in space allows at least four hot-spot observations every two days. Each day updated global maps are compiled to display the locations of all hot spots detected in the previous 24 hours. There is a drop-down list with volcano names which allow users to 'zoom-in' and examine the distribution of hot-spots at a variety of spatial scales.
MIROVA Middle InfraRed Observation of Volcanic Activity (MIROVA) is a near real time volcanic hot-spot detection system based on the analysis of MODIS (Moderate Resolution Imaging Spectroradiometer) data. In particular, MIROVA uses the Middle InfraRed Radiation (MIR), measured over target volcanoes, in order to detect, locate and measure the heat radiation sourced from volcanic activity.
