NHK: "It is getting dark – please be careful but do not give up. Do not approach rivers or go to the coastline to check the present situation. Continue evacuating to higher ground; if you have already reached a safe area, do not go back and do not let your guard down."

"Dinner time approaches," says the NHK, "but please remain mindful of aftershocks," – as the automatic aftershock warning tone sounds – "especially if you use gas."

Reports coming in of the next series of tsunami surges. Nothing above 50cm so far, but NHK announcers repeatedly warn in no uncertain terms that sudden floods can hit at any time. "Do not let your guard down, continue evacuating", they keep repeating.

Earthquake damage reports coming in: A few collapsed buildings, some people trapped, a few areas have lost power, and a few fires have broken out.

Japanese Twitter/Xitter user @fcbliebe1900 offers helpful otaku advice together with an example concert penlight power consumption chart: "For those who are suffering from power outage due to the earthquake and are using concert penlights/glowsticks as flashlights, if you use white or purple, they will discharge quickly. Even if you feel anxious and want to turn on a brighter color, please be patient."

"Cheap penlights have 3-color LEDs and RGB (red, green, and blue) to create colors by combining multiple colors (the three primary colors of light), so the batteries of the mixed colors will drain faster. However, penlights with LEDs of three or more colors are different from this graph; some white ones have long battery life, but LEDs are highly directional, so do not stare at them when they are lit."

Examination of the 1.2m tsunami measured earlier shows a flat line after the 1.2m peak. "The natural world is never that stable; we think the sensor failed after that 1.2m point, so we don't yet know that peak's true height," comments their expert.

Analysis of sea levels at various tsunami-affected points shows movement consistent with tsunami activity, though NHK notes that the normal evening tide is presently coming in as well, muddying the analysis somewhat.

The NHK continues to urge people to not return home based on calm-looking images; aftershocks may continue for several days which may push OK-looking buildings past the point of collapse, and these may yet cause a larger earthquake in the coming days.

Various warnings about keeping warm, carbon monoxide poisoning, and so forth are also included.
