Yes, seismologists experiencing an earthquake do look at their watches to time the shaking. It’s one of those cute scientist quirks.

Utah!  Mountains!  Mill Creek!  Looks cold.

Ulexite, also known as TV Rock.

It has unique optical properties caused by reflections along twinned fibers. The light internally reflects repeatedly and then displays like a TV!

Stuff of catalytic converters.  Not that I’d suggest using specimen grade platinum, y’understand. 

San Francisco earthquake, April 18, 1906. Photographer Arnold Genthe said it shows “the results of the earthquake, the beginning of the fire and the attitude of the people.” It was taken the morning of the first day of the fire. Shows Sacramento St. at Miles Place near Powell St.

The many views of Sakurajima

23rd March 2019

Sakurajima is Japan’s most active volcano. It has been consistently erupting since 1955. It used to be an island but an eruption in 1914 connected it to the main land. 

Our first view of Sakurajima was not promising.

Shrouded in cloud we we couldn’t even see the top.

By the next evening it was slightly more visible.

The ash that regularly spews from the southern peak can be seen as a dirty cloud on the righthand side of the volcano.

The third day of viewing Sakurajima was the day we were going to get a closer look, by cycling the 36km around it. Here is the story of that fun, intense and long bike ride. 

After we had recovered from that ‘adventure’, we spent our final morning in Kagoshima viewing the majesty of the volcano from some different spots.

Our first visit was to Shiroyama Park that gave us stunning views with the city in the foreground.

We also visited the Sengan-en a residence used by a noble family from the 1600s. The gardens are famous and have a lovely view across Kagoshima Bay.

Our final view of Sakurajima was perhaps one of its most dramatic. 

From the aeroplane we could really see the ash cloud prominently rising into the atmosphere. 

We had an absolutely brilliant time in Kagoshima and hope to return to Kyushu to explore further.

Sandia Mountains at Sunset Albuquerque NM - February 2018 http://michael-massa-micon.tumblr.com Sandia means “Watermelon.” The Spanish who settled Albuquerque called the mountains to the east of the city The Watermelon Mountains. There are a couple interesting aspects of geology and geography which causes this. One, the Sandia Mountains are relatively reflective. There is a lot of granite and other reflective rock in addition to the snow cap which is visible on the mountain during the winter months. Secondly, there is another set of mountains - actually a volcanic ridge flow - on the west side of the valley. This means that the sunlight is obstructed by the western ridge before sunset. If you stand in the valley near the western ridge and look over at the Sandias near sunset, you can watch the shadow of the western mountain ridge slowly flow across the valley toward the eastern (Sandia) mountains. Just as it reaches the base of the mountain, the Sandias turn a deep shade of red. That color, and their long shape, make them look like a giant slice of watermelon sitting on the desert floor. This effect is caused by the fact that red light bends slightly over an obstacle. This is what causes many of our splendid red sunsets. There is a thin band where most of the light is already blocked by the mountain ridge, but the red light is just enough to illuminate the Sandias and give them their watermelon color. Obviously, it takes a lot of patience and a bit of luck to actually capture this watermelon effect. It is also much more impressive in person than can be captured in any image, but this image does show the watermelon color fairly well. MWM

Reminiscing about studying for mineralogy…so glad it’s summer!

Important, basic stuff.  And it was fun.  I remember it like it was yesterday, but my mineralogy lab was in 1973.  Cleavage and analogues of cleavage become important again when selecting sand and gravel to use in concrete. 

California needs more of these signs.

The whole world needs more of these signs.
