Continually Updated: We’ll update this post as we hear more about who is heading to Hispaniola, either the Dominican Republic or Haiti (if the airport is reopened) to cover yesterday’s 7.0 earthquake.

Anderson Cooper is the first anchor on the ground and is already reporting.

CBS “Evening News” and NBC “Nightly News” are planning to broadcast from the region tonight. Katie Couric arrived in Santo Domingo just before 12pmET, and in Port-au-Prince at 2:30pmET.

ABC’s Diane Sawyer heads there from Afghanistan, so she likely won’t be on air from Haiti until tomorrow.

FNC WH correspondent Wendell Goler was first on Hispaniola because…he was already there. Goler was on vacation in the Dominican Republic when the earthquake struck. He reported for “FOX Report” via phone last evening.

At 2:54pmET, Brian Williams did a live phone interview from Haiti. We’ve also learned that “Nightly News” will be one hour tonight.

On Thursday, Sawyer will anchor “World News” and Robin Roberts will anchor “GMA” from Haiti. George Stephanopoulos will anchor “World News” this evening from New York, which is as previously scheduled due to Sawyer’s Afghanistan trip.

Couric will anchor an hour-long broadcast of “Evening News” for CBS this evening.

ABC “World News” will also be one hour.

> Wednesday Evening Additions: FNC’s Greta Van Susteren will head down during the day Thursday and will host “On the Record” from Miami Thursday night.

After last weekend’s criticism over a lack of U.S. cable news coverage of the post-Iranian election protests, at least two of those networks – CNN and Fox News – have been going wall-to-wall with coverage today.

CNN’s Fredricka Whitfield anchored much of the afternoon coverage getting reports from correspondents Christiane Amanpour in London, Susan Candiotti at a protest in New York at Ivan Watson at the “Iran Desk” in Atlanta. Why Atlanta? Watson explained: “It’s because we received this fax – our team in Tehran – from the Iranian government, banning us from working in Iran. From sending any dispatches without prior approval of the Iranian authorities.”

Fox News also remained in continuing coverage through the afternoon preempting taped programs “Fox News Watch” and “Journal Editorial Report” during the 2pmET hour. And weekday anchor Shepard Smith was in to host the Saturday edition of his Fox Report at 7pmET.

With a multitude of new YouTube videos from today’s protests in Tehran in favor of Mir-Hossein Mousavi, and up-to-the-moment Tweets (reliable information or not) the cable networks were able to keep the Iran protest programming going.

Smith summed up how this story has changed how networks report what’s going on. “The Associated Press is reporting at least one dead in Iran today,” said Smith. “And I’m sad to say that we’ve seen videos of at least three dead people. So for us to go forward and say ‘one dead’ would really not be as close to the truth as what we’ve seen.”

MSNBC stayed with its afternoon taped programming, producing bottom-of-the-hour updates on the protests.

> Update: Smith, still anchoring live at 8:42pmET says, “This is Fox News Channel – proud to be the only network of news in America with live and continuing coverage of a seminal moment of…what could be a seminal moment in world history. Fox News Channel is live tonight for you. The competitors are not.” CNN is airing a “Money Summit.” MSNBC is airing “Lockup.”

> Update 2: CNN’s Christiane Amanpour anchored a live hour at 9pmET while Geraldo Rivera anchored from 9-11pmET and included guest Mike Huckabee whose FNC show was preempted.

First on TVNewser: Ivan Watson will be joining CNN as an international correspondent based in Istanbul, Turkey, according to an internal memo obtained by TVNewser.

Watson previously was a producer at the network, based in Moscow. He most recently was a correspondent for NPR.

“You can ‘see’ his reports on radio, and now we will be able to watch him do his excellent storytelling on CNN,” writes Parisa Khosravi, senior vice president for international newsgathering, in the note to staff.
