Top panel: temperature evolution at four different horizontal locations at x = 1, 2, 3.14, and 4.7 Mm all at the same height y = 4 Mm. The shaded region between t = 7 to 38 min represents the eruption phase, where several MFRs leave the domain. The vertical dashed line at t = 42 min marks the time when the upper coronal part again settles down to around 1 MK. The dashed line at t = 64 min represents the onset of a thermal runaway process, which occurs first at the central x = 3.14 Mm location. Bottom panel: temperature evolution in the central (x, y) = (3.14, 4) Mm location. The temperature drops between t = 42 and 50 min with a decay rate of 156 K s⁻¹, as represented by the dashed red line.
