Map shows lava flows erupted 1983-November, 2002

Map shows lava flows erupted during the 1983-present activity of Pu`u `O`o and Kupaianaha (see large map). Lava from the Mother's Day flow (red flow on west side of flow field) reached the sea at West Highcastle early on July 19, at Wilipe`a early on July 21, and at Highcastle on August 8. From near the southwest base of Pu`u `O`o, the Mother's Day flow passes along the west side of the flow field and into the forest, where it started a large wildfire in May that continued into late July. By June 10, the Mother's Day flow had reached the base of Paliuli, the steep slope and cliff below Pulama pali and just above the coastal flat. At the base of Paliuli, the Mother's Day flow abruptly spread laterally in a series of small budding flows to cover an area nearly 2 km wide, gradually moving seaward until the West Highcastle and Wilipe`a lobes finally reached the ocean and started building benches. Activity at West Highcastle ended in early August, but entry began soon thereafter at Highcastle, eventually burying tiny kipuka of the Chain of Craters Road. The Wilipe`a entry died away slowly and had ended by mid-August. Highcastle and neighboring Highcastle Stairs entries ended on about August 23. For a time there were no active entries. Then Wilipe`a was reactivated on September 3 and remains active as of November 25. West Highcastle likewise renewed its activity on September 16-17, died away during the night of September 18-19, and returned soon thereafter to continue to time of mapping. East arm of Mother's Day flow branched from Highcastle lobe in late October and sent three fingers into ocean at Highcastle on November 15, West Lae`apuki on November 19, and Lae`apuki on November 20. Of these, only Lae`apuki (the eastern of the two entries labeled "Lae`apuki" on map) was still active on November 25, but it had stopped by November 29.
