How did the viewers of the 1959 eruption protect themself from the heat

it seems i'm maybe to late but, the answer ish(u sorry if im wrong, lm.ao, this ish all i know about dish, lm.a) Earthquake swarms & summit tilt precede eruption.

Three months before the Kīlauea Iki eruption, between August 14 and 19, 1959, a swarm of deep earthquakes was recorded on the seismographs at the Hawaiian Volcano Observatory. The earthquakes were located about 55 km (35 mi) below the volcano. By October, tilt surveys of the caldera, using the new water-tube tiltmeter network, indicated that the summit reservoir of Kīlauea was beginning to inflate with new magma. Scientists later concluded that magma began its upward journey during the August swarm from about 55 km (35 mi) below the volcano.

Another series of earthquakes—shallow tiny events beneath the caldera—began in mid-September near Halema‘uma‘u Crater. By November 1, more than 1,000 tiny earthquakes were being recorded per day. Scientists conducted another caldera tilt survey during the second week of November and discovered it was swelling at least three times faster than during the previous months. Magma was moving into the summit reservoir at a high rate.

During the afternoon of November 14, earthquakesbeneath the caldera suddenly increased about tenfold in both number and intensity. For five hours, the entire Kīlauea summit region shook as seismic tremor signaled magma was forcing its way from the summit reservoir toward the surface.
