0:00:11 > 0:00:14Hello, I'm Ricky with your Monday morning Newsround.
0:00:14 > 0:00:17First, thousands of people in central Italy have spent
0:00:17 > 0:00:20the night sleeping in cars, tents and shelters after
0:00:20 > 0:00:24the country's most powerful earthquake in almost 40 years.
0:00:24 > 0:00:26These aerial pictures show the damage caused
0:00:26 > 0:00:29by yesterday's tremors.
0:00:29 > 0:00:32Around 20 people have been injured, but thankfully no-one has died.
0:00:32 > 0:00:36It's the fourth quake to hit the area in three months and there
0:00:36 > 0:00:38are warnings of aftershocks.
0:00:38 > 0:00:42BBC reporter Jenny Hill is in the town of Norcia.
0:00:42 > 0:00:45It's a really miserable morning for people waking up here in Norcia.
0:00:45 > 0:00:47They've spent the night in tents.
0:00:47 > 0:00:49Thousands of people in emergency accommodation.
0:00:49 > 0:00:51They don't know what's coming next.
0:00:51 > 0:00:53Many of them don't have homes to go back to.
0:00:53 > 0:00:57There are huge question marks over the future, and one of those
0:00:57 > 0:01:02question marks, Perhaps the biggest one of all,
0:01:02 > 0:01:03question marks, perhaps the biggest one of all,
0:01:03 > 0:01:06is how on earth do you protect a country like Italy,
0:01:06 > 0:01:08a region like this, which is notoriously vulnerable
0:01:08 > 0:01:10to seismic activity, from further damage?
0:01:10 > 0:01:11Moving on.
0:01:11 > 0:01:12Time for a quick sports round-up.
0:01:12 > 0:01:15Andy Murray is one step closer to becoming tennis world number one
0:01:15 > 0:01:19after beating Jo-Wilfried Tsonga to win the Vienna Open title.

0:01:25 > 0:01:28not make the final.
0:01:28 > 0:01:31Lewis Hamilton's hopes of winning the Formula One World Championship
0:01:31 > 0:01:34are still alive after winning the Mexico Grand Prix.
0:01:34 > 0:01:38He's now 19 points behind Mercedes team-mate Nico Rosberg
0:01:38 > 0:01:40who leads the title race.
0:01:40 > 0:01:44And Chelsea are keeping the pressure on the Premier League title race
0:01:44 > 0:01:47after a 2-0 win over Southampton.
0:01:47 > 0:01:50Goals from Eden Hazard and Diego Costa mean that the Blues
0:01:50 > 0:01:52are fourth in the table, one point behind the
0:01:52 > 0:01:57leading three teams.
0:01:57 > 0:01:59Well, I'm sure you know it's Halloween today,
0:01:59 > 0:02:02that time of year when we go trick-or-treating, carve
0:02:02 > 0:02:09petrifying pumpkins and get frightened for fun!
0:02:09 > 0:02:12But how do our bodies change when we feel fear and why
0:02:12 > 0:02:13does it happen?
0:02:13 > 0:02:15Martin, Jenny, Leah and I have been finding out the science
0:02:15 > 0:02:19behind being scared.
0:02:20 > 0:02:22Right then, what movie have we got?
0:02:22 > 0:02:27Well, it's Halloween, Jen, isn't it, so we've got a scary movie.
0:02:44 > 0:02:46I can't believe you guys were scared of that.
0:02:46 > 0:02:49Nothing like that ever scares me ever.
0:02:49 > 0:02:52Come on, Leah, I can tell you were scared.
0:02:52 > 0:02:53No.
0:02:53 > 0:02:54Yes, it's in the science.
0:02:54 > 0:02:55Look.
0:02:55 > 0:02:57Science can tell us when we're scared.
0:02:57 > 0:03:00We can see it in the way our body reacts.
0:03:00 > 0:03:04The thing that you might feel first of all is your heart beating very,
0:03:04 > 0:03:06very quickly, sending blood around the body in order to react
0:03:06 > 0:03:08to the danger.
0:03:08 > 0:03:11Something else might be that you start to get sweaty.
0:03:11 > 0:03:15You might also see the hairs on your skin start to stand up.
0:03:15 > 0:03:18If we were furry creatures that would make us look much bigger
0:03:18 > 0:03:22and perhaps scarier than the thing which is scaring us.
0:03:22 > 0:03:25But we don't have lots of fur, so we see little lumps
0:03:25 > 0:03:27and bumps on our skin.
0:03:27 > 0:03:28Goosebumps.
0:03:28 > 0:03:31Your muscles also become very, very tense.
0:03:31 > 0:03:33They're ready to do something which means you might
0:03:33 > 0:03:37grip on to something really, really tightly.
0:03:37 > 0:03:41And the pupils of the eyes may dilate, so that your eyes look very
0:03:41 > 0:03:44wide, letting in lots of light so that we can make sense of what's
0:03:44 > 0:03:46going on in the surroundings.
0:03:46 > 0:03:47But there's nothing wrong with being scared.
0:03:47 > 0:03:50It's a natural process and when we're with friends
0:03:50 > 0:03:53in the right situation, being a little scared can be
0:03:53 > 0:03:56great fun but I'm sorry, Leah, we really can tell
0:03:56 > 0:04:00when you're scared.
0:04:00 > 0:04:02No, guys, I'm not convinced.
0:04:02 > 0:04:05There isn't anything that scares me.
0:04:05 > 0:04:09Aaargh!
0:04:09 > 0:04:12Next, one celebrity's biggest fears were realised when they were voted
0:04:12 > 0:04:14out of Strictly on Saturday night.
0:04:14 > 0:04:19Look away now if you don't want to know.
0:04:19 > 0:04:21Anastacia became the sixth celeb to leave the show along
0:04:21 > 0:04:23with her partner Brendan Cole.
0:04:23 > 0:04:26She faced Daisy Lowe in the dance off, but her jive didn't impress
0:04:26 > 0:04:33the judges and they all voted for Daisy to stay.
0:04:33 > 0:04:35And over on X Factor, there was a huge shock
0:04:35 > 0:04:37as Gifty Louise was voted off the show.
0:04:37 > 0:04:40The singer lost out to girl band Four of Diamonds after she failed
0:04:40 > 0:04:43to impress judges in the sing off.
0:04:43 > 0:04:44That's all from me.
0:04:44 > 0:04:47Newsround's back right here in half an hour when we'll be
0:04:47 > 0:04:51taking a look at some of your petrifying pumpkin pictures.
0:04:51 > 0:04:54Go online now to send us yours if you haven't done so already
