Geological Summary

The 5-km-wide island of Moti, also known as Motir, is part of a roughly N-S-trending chain of islands off the western coast of Halmahera Island. Moti is located north of Makian volcano and south of Mare and Tidore islands and is surrounded by coral reefs. The truncated, conical island rises to 950 m and contains a crater on its SSW side. Moti was mapped as Holocene in age by Apandi and Sudana (1980). An insignificant eruption was reported in 1774 or shorter before, but Gogarten (1918) indicated that this event was confused with the October 1773 eruption of nearby Gamalama volcano, which could have dropped ash on Moti.

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.
