Aloha! Last night’s tours were successful with both of our groups safely getting up to some surface lava. The tiltmeter, which can be found on the Hawaiian Volcano Observatory website, measures the inflation/deflation of the magma storage areas beneath the caldera or Pu’u O’o. An inflation would indicate that more lava is being produced. The tiltmeter was on a deflation, then changed to inflation, and is now back to deflation. The amount of lava was not as much as the past days, but we were still able to find some surface lava. This is in response to the deflation that happened for two days. We will be having tours going out tonight, but we will be keeping an eye on the tiltmeter. Until next time, Aloha!
