Earthquake occurrence reveals magma ascent beneath volcanoes and seamounts in the Banda Region

Popis výsledku v původním jazyce

Characteristic seismicity patterns beneath the volcanic arcs of the Banda region, SE Asia, suggest that magmatic processes have recently occurred beneath submarine portions of the arcs, forming yet-unrecognised submarine volcanoes. We have found that almost 50 % of earthquakes spatially associated with the Banda and Ambon volcanic arcs occurred in sequences with epicenters often concentrated in a small area and foci distributed in vertically elongated domains. The most pronounced occurrence of such earthquake series and swarms was observed in the area of the Manipa submarine basin (latitude 3.75 degrees S, longitude 127.5 degrees E, ESE of Buru Island), the remarkable morphology of which resembles a huge caldera (60 km in diameter) with a distinct coneseamount in its center, reaching almost 3000 m above seafloor. Another candidate for an unrecognised submarine volcano is an area between volcanoes Banda Api and Manuk, with a huge 1973/74 earthquake swarm.
