Parieutin - page 6 
June 13 - eontd 
The flow was advancing to the east, at the foot of the cone at 15 meters 
per hour, into the destroyed pine forest. 
Made a circuit of the cone. The south side entirely intact. Remarkably 
how few bombs collected at the base of the cone, the talus not more than one 
to three meters high. 
noticed many flat slivers of compact basalt in the ash. Also large bombs 
with trains shooting out of crater. The bombs, upon impact also yielded such 
slivers. Perhaps due to disintegration of the compact bombs, during flight. 
4 PM - Arrived at Parieutin and found the lava advancing on the village. 
Only about 80 meters from the first house, advancing at rate of 21 meters per 
hour. Many houses being dismantled and moved. After passing through the 
narrow valley, the flow spread, advancing but little to the north, more to the 
west, but mostly northwest, 
6 HI - A slow column of smoke rising from the cone, with low surf sound 
and continuous slow locomotive puffs, perhaps the latter from north crater. 
Beautiful bright red cascade of lava from mouth alongiside pyramidal peak. 
Dense steam from fumaroles drifting to the east. 
Eruption rather quiet all day, increasing about 9 PM to normal display.

Went to Parieutin in the morning. The west side of the flow was within 
20 meters of the first house. The advance was greater to the northwest 
toward San Juan, but its advance in all directions was slow. A number of 
weak fumaroles were already formed (24 hours after flow) yielding thin white 
yellow and orange crusts. Parieutin was being dismantled and evacuated. 
In the afternoon plant some sublimate tubes. 
Later went to east flow. This has spread between the old flow and the 
hills to the east. In general the flows follow the slope but they override 
small ridges by flowing up hill. The east flow is thicker than the west flow 
and is advancing more slowly, 5-10 meters per hour depending on the slope. 
It is a viscous lava, bulging out in breadcrust fashion, or rolling boulders 
off its face. No odor, little fumes, no noise except that of sliding rock. 
Evening. Magnificient display from crater and flow. The latter tiro 
cascades of brilliant orange from the boca to the base, then a myriad of 
lights along the flow front, like looking upon a city from a distant hill. 
The hummocks with glowing cracks like outlying villages. 
9:50 - The boca of the flow began to spurt with locomotive like sound. 
Lava bubbles, estimated as 5 meters high formed and burst, sometimes accom- 
panied by increased flow of lava from boca, throwing hot gobs 50 meters high. 
During this period, the north crater resumed weak activity, throwing out small 
rocks and incandescent dust, accompanied by much black smoke at intervals or 
sometimes a thin wisp of smoke. It appears that the north crater is being 
rapidly filled up by ejectamenta from the south crater. 
The west wall of the break is being built up, the east wall much in its 
original condition. Very few rocks now fall on east slope.
