| Abstract | The 1859 eruption of Mauna Loa, Hawaii, resulted in the longest subaerial lava flow on the Big Island. Detailed descriptions were made of the eruption both from ships and following hikes by groups of observers [1, 2]; the first three weeks of the eruption produced an ‘a‘ā flow that reached the ocean, and the following 10 months produced a pāhoehoe flow that also eventually reached the ocean [3]. The distal por-tion of the 1859 pāhoehoe flow component (Figure 1) Figure 1. Map of the distal pāhoehoe component of the 1859 Mauna Loa flow. Contours are derived from topography shown in USGS 1:24K maps. Image base is mosaiced air photos from Google Earth. Green lines show local flow directions inferred from both field observations and the regional topography. Purple lines identify discreet flow lobes recognized in the field. . 3. Map produced by LSC. Red line shows location of DGPS data in Fig. 2. Blue line shows location of DGPS data in Fig 3. includes many distinctive features indicative of flow inflation [4, 5]. Field work was conducted on the distal 1859 pāhoehoe flow during 2/09 and 3/10, which al-lowed us to document several inflation features, in or-der evaluate how well inflated landforms might be de-tected in remote sensing data of lava flows on other planets. |
