Laplace 1 (L1), located in Sinus Iridum, has a diameter of 7.6 ± 0.3 km, height of 230 ± 20 m with an average slope of 3.40° ± 0.3°. The edifice volume is determined to 5.5 km3. Laplace 1 belongs to class B1.
Laplace 5 (L5), located in Sinus Iridum, has a diameter of 9.0 ± 0.5 km, height of 125 ±15 m with an average slope of 1.60° ± 0.10°. The edifice volume is determined to 3.7 km3. Laplace
5 belongs to class B2. Rheologic modelling indicates that it was
built by lava of moderate viscosity of 2.4 x 105 Pa s, erupting at a
high effusion rate of 110 m3 s-1 over a period of time of
1.2 years. The second elongated dome, named Laplace 6 (L6), with a low average
slope of 0.7° ± 0.10° is considered a putative intrusive dome, and modelling
results indicate it belongs to class In2.
