Looks really really silic blue....

Looks almost pretty enough to be worth the tropical climate.
(Actually one of my Profs did a pile of work in Vanuatu decades ago -
so if I ever got the chance to go, I'd know where to get hand's-on
climate and equipment advice.)

Lake Vui turns to mud-brown...

FTFA:
Ambae Volcano (Vanuatu)
15.38 S, 167.83 E,, summit elevation 1496 m, Shield Volcano
Sunday 8th January 2006
Displaced people living in the relocation centres on Ambae
Island have began returning home over the past two weeks. The
waters of Lake Vui have changed from their normal aqua blue to
a muddy brown. Eruptions at Ambae volcano continue at low levels
with mainly phreatic activity. The volcano remains at level 2
alert. A cone is building inside the lake, forming a small
island. There are two active vents, one ejecting water, rocks
and mud, and the other is producing a tall column of steam and
gas (up to 8,000-10,000 feet). Villagers no longer fear the
volcano, and are admiring the beautiful sand beach which has
formed in the lake. They are hopeful the volcano will attract
more tourists to the island.

Hmmm, that does put a number of new contexts around the original
report.

Hey, no one's commented on my idea for why the water is red.
