Activity for 2/3-2/4:
At the Summit:
At Halema`uma`u crater lava was visible through 3 openings in the bottom of the crater. The glow from the lava is more intense than it has been recently. Nine earthquakes were able to be located below Kilauea last night. Small background earthquakes also occurred, but only the larger earthquakes are able to be located. Pieces of ash were carried out of the crater by the gases leaving the vent.
TEB Vents: Lava continues to flow out of the TEB vents and down the flow field.
Click here and look at recent pictures of Kilauea. Specifically, be sure to look at the February 3rd pictures of aa lava. Then, search for on the internet or look in a book to read about characteristics of aa lava. Respond to this post by describing some characteristics of aa lava (what is aa lava like?).

Aa lava is rough and moves in a roller-like way. It is basaltic lava.It is made up of broken lava blocks called clinkers.Aa lavaI flows slower then Pahoehoe lava because it has a greater viscosity then it.

The aa lava is chunkyand rough. It moves much slower than pahoehoe. nine earthquakes have occured becauseof the constant erupting of Kilaeua

Aa Lava is a flow that can be identified as a dark flow. Aa looks jagged,ragged,and billowy. Aa is pronounced “ah-ah.” Aa flows are emitted from a vent at high rates ranging to 50 km an hour. Aa has a very high viscosity, which makes it very slow. This is a video about Kilaeua and a Aa flow. This is the URL: http://www.youtube.com/watch?v=iyIV5fd1Aww.

Unlike pahoehoe lava, aa lava is not smooth and billowy, but rough and jagged. Pahoehoe and aa are made up of different combinations of gasses and heat. Aa lava flows slowly, due to it's high viscosity.
-McKenna R(A1)-
Pahoehoe is much faster flowing then aa, meaning aa has more viscosity than pahoehoe.
Aa lava is block like and has a higher viscosity than pahoehoe lava. Aa lava flows slower than pahoehoe lava.

Aa lava has a black color. It is also very rough and moves very slow. When it stop and starts hardening it hardens into a rough round shape like rock. It has a high viscosity, and it also made up of lava chucks that are compressed together.
Aa has a high level of viscosity, which means it moves slowly, unlike pahoehoe. Aa is slow and clumpy, while pahoehoe is fast and smooth. Aa lava also is a dark color.

pahoehoe travels fasteer than aa lava, So Aa lava has more viscosity. aa lava is rough and jagged, while pahoehoe is smooth and puffy.
Aa lava is cooler and moves slower than pahoehoe.Aa has higher viscosity and when it hardens it is rough and jagged.

Aa lava has much more viscosity than Pahoehoe lava meaning that Aa lava flows much slower than Pahoehoe. Aa lava is very thick,and has more viscosity.

Aa lava is characterized by a rough surface composed of broken lava blocks. Aa lava is very thick. Aa lava has more viscosity than Pahoehoe. The more viscosity, the slower the lava flows.
I think that the Aa Lava looks just like an explosion of little bright orange pebbles. It is the slowest kind of lava. It looks very dangerous and probably has a pillow- like texture.
Aa lava is rough also it is basaltic lava. Aa lava flows slower then Pahoehoe lava because Aalava has a greater viscosity then pahoehoe. Another is that it is very solw ,and lastley when it hardens it is jagged and clumpy pebbles.
Aa lava is rough and jagged lava. It flows slowly because it has greater viscosity. Pahoehoe flows faster because of this. When it hardens it forms jagged and lumpy pebbles.
Aa lava is very slow, which it means it has a high viscosity. Aa lava hardens into chunks that are jagged and rough. It is very dark when it hardens. When it hardens, it has the appearance of rock.
Aa lava is rough and runs at a very slow pace. It is solidified and clinkery. The surface is sharp and broken down into many different pieces of magma. Since Aa lava is slow, it has a higher viscosity than Panhoehoe which has a lower viscosity.
-Kensi Olson
Aa lava has a high viscosity. That means that it flows slowly. Aa lava is very rough and jagged. It hardens but then cracks again. When it hardens for good, it willform lumpy rocks and peebles
Aa lava is really slow. Pahoehoe is faster than Aa lava, therefore Aa has higher viscosity. Aa lava means "stony rough lava" or "burn or blaze" in Hawaiian. Check out this video of Aa lava.----http://www.volcanovideo.com/Movies/Aa&PhhCU.mov.
(The Aa lava is on the right side) It really really slow!
Aa lava is basaltic lava with a rough surface. Aa lava has a high viscosity level;it is slow moving. Aa is black colored.

Aa lava has a rough surface with sharp edges. Aa lava is basaltic lava. Aa lava is slow which causes it to have a high viscosity. Aa is a black colored lava.
Aa lava is very rough, jagged and chunky. Aa lava moves very slowly.Aa lava is aldo very drak in color like a black or a dark brown. Aa lava is balsaltic lava wich gives it it's high viscosity.
-Bridget F.
Aa lava is a basaltic lava that is rubbery.
