The diameter is 2 km (1.2 mi), an it is locatit 24 km (15 mi) from Koblenz, 8 km (5.0 mi) from Andernach an the Rhine river, an 37 km (23 mi) from Bonn. Its last volcanic eruption, which wis a Plinian eruption, wis aroond 11,000 B.C., wi a Volcanic Explosivity Index (VEI) o 6, havin the same magnitude as the Plinian eruption o Munt Pinatubo in 1991. It is pairt o the Eifel region, an the East Eifel Volcanic Region, which wis formed after the collision o the African an Eurasian continents millions o yeirs ago.[3][4][5] Bubbles o odorless CO2 gas called mofettas are released from the loch, which means that the volcanae is dormant. Tae the west o the loch is the Maria Laach Aibey, built in 1092 by Henry II o Laach, Coont o the Hoose o Luxembourg.
