  abstract = {{T}he basaltic effusive eruption at {M}t. {F}agradalsfjall lasted from 19 {M}arch to 18 {S}eptember 2021, ending a 781-year repose period on {R}eykjanes {P}eninsula, {I}celand. {B}y late {S}eptember 2021, 33 near real-time photogrammetric surveys were completed using satellite and airborne images, usually processed within 3-6 hr. {T}he results provide unprecedented temporal data sets of lava volume, thickness, and effusion rate. {T}his enabled rapid assessment of eruption evolution and hazards to populated areas, important infrastructure, and tourist centers. {T}he lava flow field has a mean lava thickness exceeding 30 m, covers 4.8 km(2) and has a bulk volume of 150 +/- 3 x 10(6) m(3). {T}he {M}arch-{S}eptember mean bulk effusion rate is 9.5 +/- 0.2 m(3)/s, ranging between 1 and 8 m(3)/s in {M}arch-{A}pril and increasing to 9-13 m(3)/s in {M}ay-{S}eptember. {T}his is uncommon for recent {I}celandic eruptions, where the highest discharge usually occurs in the opening phase.},
