This is already an island building up around the vent as the volcanic tephra piles up.
2
While the tephra has gradually washed away over the years, the hard lava core has proved far more resilient.
3
They are constructed of loose piles of volcanic debris (tephra) and lava flows on relatively steep slopes.
4
It consisted of roughly two-thirds tephra (rock fragments thrown up during an eruption) and one-third rapidly cooling lava.
5
Vigorous eruptions of steam and tephra were accompanied by an enhancement of the normal fine-weather potential gradient, and lightning was often observed.
Uso de ejecta en inglés
1
Not the meteorite itself, but ejecta: shrapnel hurled out from the impact site.
2
Calderas marched across his view, the terrain tortured and broken with faults and ejecta.
3
This ejecta would thrust the asteroid in the opposite direction.
4
An ejecta of lava spew shot back and hit the underside of the lander.
5
New island chains, frequently arc shaped, had been created by ejecta and by volcanic activity.
6
The solar ejecta is set to hit Earth in the early morning hours in North America.
7
Some of the ejecta crap's fouling the scaffold.
8
Lots of carbon comes up with kimberlite ejecta, but most is vaporized or turns to graphite.
9
The ejecta, the ejected material from that impact was bigger around than the diameter of the earth.
10
The criss-crossing lines are made up of mounds of "ejecta" thrown up by whatever struck the planet.
11
They included a strenuous 1.3-kilometer trek through the hummocky ejecta blanket surrounding 300-meter-wide Cone Crater.
12
The thought barely registered with her when she realized that these weren't snowflakes, but was instead ejecta from the impact.
13
The ejecta contain more calcium than observed in other types of supernovae and probably large amounts of radioactive (44)Ti.
14
Her head swam at all that had happened and she kept her eyes squinted as the ejecta still drifted around her.
15
The observed radio emission can be explained by either a collimated ultrarelativistic jet, viewed off-axis, or a cocoon of mildly relativistic ejecta.
16
But we can't send humans -way too expensive, besides it's a fifty-yearrun even if we go for short-periodKuiper ejecta.
