Lovatnet (also Loenvatnet) is a lake in the municipality of Stryn in Vestland county, Norway.

Landslides into the southern end of the lake from the mountain Ramnefjellet caused two major tsunamis in 1905 and 1936.

The waves destroyed the villages of Bødal and Nesdal near the southern end of the lake, killing 61 people — half their combined population — and 261 farm animals and destroying 60 houses, all the local boathouses, and 70 to 80 boats, one of which — the tourist boat Lodalen — was thrown 300 metres (328 yd) inland by the last wave and wrecked.

At the northern end of the lake, a wave measured at almost 6 metres (20 ft) in height destroyed a bridge.

[2] Geologists studied the 1905 event and concluded that little risk existed for future disasters like it, so the towns along the lake were rebuilt.
