The 2018 lower East Rift Zone eruption (LERZ) at Kilauea Volcano, HawaiModified Letter Turned Commai, was the largest event of the last 200 years at the LERZ. Here, we present a lava discharge rate estimation of this eruption by combining a joint analysis of multi-sensor infrared (IR) satellite remote sensing imagery of the Moderate Resolution Imaging Spectroradiometer (MODIS) and the Visible Infrared Imaging Radiometer Suite (VIIRS) with laboratory measurements of lava properties. The time-averaged discharge rate (TADR) based estimation of the erupted lava volume resulted in circa 9.24 x 10(8) +/- 4.62 x 10(8) m(3) for the subaerial part of the 2018 LERZ eruption. The lava effusion at the LERZ began on 3 May 2018, with relatively low mean output rates of 2.82 +/- 1.41 m(3) s(-1), which then almost doubled after 12 May to 4.94 +/- 2.47 m(3) s(-1), increased after 19 May to 64.97 +/- 32.48 m(3) s(-1) and from 28 May onwards until beginning of August 2018 up to 137.67 +/- 68.83 m(3) s(-1).
